Clogged heat exchanger, gas burner and chimney

Fuel consumption increases due to blockages in the gas boiler elements:

1. Scale accumulations in the heat exchanger of the unit. Lime deposits formed during operation prevent rapid heat exchange between the circuit and the coolant. As a result, in order for the liquid to reach the set temperature, the burner needs to heat the heat exchanger longer. To eliminate the problem, you need to remove the element, wash it with a solution and clean it with a brush.
2. Gas burner clogged. Gradually, the burner nozzles or its igniter become clogged with soot and soot, which subsequently prevents the passage of gas and maintaining a stable flame. As a result, the burner must burn more gas in order to heat the coolant to desired temperature. The problem can be solved by cleaning the boiler gas burner.
3. Chimney blockages. The soot and soot accumulated during the combustion process clog the pipe for removing combustion products, which disrupts the air supply to the burner, which disrupts the stable combustion process. Proper air supply and smoke exhaust reduces gas consumption. Lack of oxygen leads to a decrease in the amount of heat released during combustion and to the formation of soot.

These defects can have a long-term effect Negative influence and not be noticed by the owners. To prevent this, it is necessary to clean the boiler elements every year.

Has your house already been built? Thinking about choosing energy resources for autonomous heating? There are several sources of thermal energy: natural gas, firewood, coal, fuel oil, liquid fuel, electricity. The technical representative of the BAXI company in the Volga region, Sergey Nikolaevich Shipov, will talk about the use of liquefied petroleum gas as fuel.

The concept of liquefied gas

In Russia, liquefied petroleum gas is usually called hydrocarbon gases (LPG) based on a mixture of light hydrocarbons liquefied under pressure with a boiling point from -50 to 0 °C. The composition of such gas can vary significantly; the main components are propane, propylene, isobutane, isobutylene, n-butane and butylene. Today, for autonomous gas supply systems, mixtures of liquefied technical propane and butane (SPBT, petroleum gas, corresponds to GOST 20448-90) are used, rather than liquefied natural gas (methane). The latter is stored at low temperatures in special cryogenic vessels, requires additional evaporators and is economically justified only for heating a large group of houses.

Liquefied hydrocarbon gas (LPG) turns into a liquid state with a slight increase in pressure. Then it can be easily transported and stored. With a decrease in pressure or a slight increase in temperature, the “liquid” gas begins to evaporate and enters the gas phase, ending in saturation. The saturated vapor pressure depends only on the ambient temperature and does not depend on the amount of liquid.

One liter of LPG produces about 0.25 m3 of gas phase. In winter, gas pressure decreases and gas phase supply performance decreases. If vapors are taken intensively (for example, turn on the boiler at 100% power), then accelerated evaporation of the liquid will lead to its cooling and, therefore, to a decrease in productivity. To obtain the required volumes of gases, the number of LPG containers is increased. Propane has an optimal set of necessary properties. It steadily supplies the gas phase even in frosty conditions, but is relatively expensive and good only in winter. In summer, when it is hot, its vapor pressure reaches limit value, permissible for the walls of the vessel (1.6 MPa), so propane is diluted with cheaper and not intensively evaporating butane.

LPG is not recommended to be placed in basements and even basements if the window area in them is less than 1 m2. Because for complete combustion SPBT requires a lot of air, in boiler rooms it is necessary to provide good ventilation. In addition, the premises must be organized daylight, as well as install a gas leak detection sensor and an automatic shut-off valve with self-powered power.

Application area of ​​LPG

Due to its environmental friendliness (cleanliness of combustion) and relatively low production and processing costs, propane-butane gas has received wide application for production and economic needs population. The scope of application of liquefied petroleum gas is wide. For example, LPG is used as a source of heat, fuel for vehicles, raw materials for the production of aerosols, etc.

The use of LPG as a raw material for home heating retains all the advantages of autonomous heating using natural main gas, with the exception of current gas costs. But it often happens that even with a relatively close location of the main gas pipeline, the prospect of connecting to the “cherished pipe” remains far beyond the horizon. In this case, you should approach the choice of fuel with a calculator. For example, let’s consider heating a 300 m2 cottage with three types of fuel: liquid (diesel) (DT), mains electricity and LPG. On average, such a room consumes 80,000 kW of energy per year for heating. Based on this figure, we will make the following calculations:

Table 1. Economic comparison of heating costs for a cottage with an area of ​​300 m2

Prices are valid for June 2011. Average gas consumption is 0.86 kg per 10 kW.

The presented table for estimating fuel consumption and costs shows a clear feasibility study for the use of LPG. Additional advantages of bottled gas, in contrast to diesel fuel and electricity, will be: the ability to organize various options preparation of domestic hot water (boiler or flow-through heat exchanger) and minimal emissions into the atmosphere, unlike diesel fuel. Only NOХ, CO2 and steam will be emitted with flue gases. When using condensing boilers as heat generators, harmful emissions are reduced significantly, and gas savings can reach 30%!

Autonomous LPG gas supply

Having chosen LPG, next step The question arises about the actual location of gas reservoirs and the gas supply to heat-generating installations.

Two types of containers are used: gas cylinders and gas tanks.

Gas cylinder - steel welded cylinder for liquefied hydrocarbon gases (propane) GOST 15860-84 is intended for transportation and storage of propane with various capacities of 50, 25, 12 and 5 liters ( operating pressure– 1.6 MPa).

Installation of gas supply using small containers should be carried out with at least 3 cylinders. This allows you to increase the evaporation surface and reduce the risk of freezing of the cylinders. It is important to use pressure regulators with the parameters required for a given boiler and type of gas. The use of regulators not intended for LPG is not allowed!

Gas holder – a reservoir designed for storage and regasification of liquefied hydrocarbon gas during gasification residential buildings, municipal and agricultural facilities. Gas holders are distinguished by volume (from 0.25 to 100 m2). Unlike cylinders, they provide a larger evaporation surface and a larger storage volume of LPG and, as a result, fewer refills.

In any case, to achieve safe use of LPG, you will need to design the gas supply at home. The complex and time-consuming process consists not only of developing optimal scheme gas supply to the home, but also includes receiving a number of permitting documents and registration of an autonomous gas supply system. In some cases, LPG is used as a backup fuel, but to transfer the boiler it is necessary to carry out a number of operations.

Application of LPG with boilers

When choosing a heat generator, you should pay attention to the possibility of its operation on LPG. Not all boiler manufacturers allow conversion to another type of fuel.

BAXI equipment running on natural gas, can also be used as a heat generator for LPG. To convert BAXI atmospheric boilers and water heaters to LPG (in instructions G31), the installer only needs to perform three important operations:
1. “Inform” the board that the boiler is now operating on G31 (LPG) (change a number of parameters F, or change the position of the jumper/toggle switch to GPL);
2. Replace the existing nozzles with nozzles with a smaller bore (purchased separately, see Table 2);
3. Reset the gas valve (according to parameters G31).

For condensing boilers, the operation occurs at no additional cost:
1. Replace the gas diaphragm located at the outlet of the gas valve (included in the kit);
2. Set parameters H using the control panel display;
3. If necessary, adjust the gas valve.

The use of LPG with condensing boilers not only reduces the level of emissions into the environment, but also significantly reduces gas consumption.

Table 3. Approximate consumption of liquefied gas for residential heating

Features of using LPG

Active use by owners of private houses and industrial enterprises Autonomous LPG gas supply system makes it possible to evaluate its advantages, advantages and reliability.

Low fuel consumption of excellent quality, convenient operation and long service life gas equipment– these are the undoubted advantages of autonomous gas supply. Complete independence from the main natural gas network and the ability to receive hot water and heat all year round attracts owners of private houses. Don’t forget about the possibility of quickly reorienting BAXI equipment from methane to propane and back. In addition, autonomous gasification is an economically viable LPG supply system compared to heating sources such as electricity and diesel fuel.

Gas technology has gained popularity due to the high efficiency that is generated during the combustion process. In addition, the exhaust gases contain a minimal amount harmful substances. At the time of buying heating equipment We want to get an efficient and economical device. Therefore, it is important to calculate in advance the actual gas consumption in the boiler.

What factors affect fuel consumption?

Years of use different types fuels have proven that gas is 30% cheaper than diesel and electricity. Most users connect to a common pipeline, since when using gas in cylinders, funds are spent on delivery.

Factors that should be taken into account when choosing a heating boiler to avoid high fuel consumption:

• Heat losses. The consumption of a gas boiler directly depends on heat loss through walls, windows, doors, and roof. Therefore, preliminary calculations power of technology. The area of ​​the room, the quality of insulation, and the purpose of adjacent rooms are taken into account.

• Settings system. Automatic installation includes sensors that record temperature external environment and configure the operation of the unit in optimal mode. This allows you to save on consumption.
• Type of equipment. When using a condensing unit, gas consumption is reduced by 15–20%. Unlike the conventional convection type, the condenser contains a separate heat exchanger to direct the energy of the combustion products to heat the system. This increases the coefficient of performance (efficiency) to 100%.

The presence of one or two circuits also matters. A single-circuit device works only for heating. Whereas double-circuit - for hot water supply (DHW) and heating. Consequently, its consumption will be greater.

Units with a closed combustion chamber consume less fuel than those with an open combustion chamber. Duration also affects heating season. After all, in winter the boiler works at maximum, while in summer it works at minimum, only for heating hot water.

Why do appliances consume a lot of gas? This is all due to poor insulation of the building and scale deposits.

The table shows an example of maximum consumption for 210 days.

Knowing how many cubes are consumed per hour, you can calculate the rate per day and per month.

How to calculate fuel consumption

To heat a private house or apartment, calculations are used that are based on two parameters: the power of the heating equipment and the area of ​​the room. An average calculation is taken - 1 kW per 10 m².

Many articles have been written on this topic, but few clarify that the unit of measurement kilowatt is thermal power, not electric. This misleads many users.

It would be more logical to measure work on natural gas in cubic meters (m³ per hour), and on liquefied gas in kilograms (kg/hour).

On average, 1 kilowatt of thermal power consumes 0.112 cubic meters per hour of main gas.

For example, let’s take the “” unit with a power of 17.4 kW. The passport data indicates the consumption of main fuel is 1.87 cubic meters, liquefied gas - 1.3 kg/hour. These values ​​are valid for continuous operation, but if the device is constantly running under wear and tear, then the parts will quickly fail. When choosing, add plus 20% to the indicated power.

“AOGV” in our example will be installed in a room of 140 m². Now take a look at the rates (approximately):

• Natural fuel: 3.9 rubles per cubic meter.
• For bottled gas, the calculation is based on the volume of the container. For 50 liters - 600 rubles. The cylinder is not completely filled with propane, approximately 80% (21 kg). This means: 600/21= 28.6 rubles. You can add shipping costs here.

The daily calculation for the main connection will be as follows: :

Day (24 hours) x 1.87 (cubic meters/hour)/2 = 22.4 cubic meters. To find out the cost: 22.4 x 3.9 (tariff) = 87.5 rubles.

Per month:

22.4 (daily consumption) x 30 (number of days) = 672 m³.

Per year (seven months - heating season):

7 x 672 (monthly norm) = 4,704 m³.

When working on propane per day :

24 (hours) x 1.3 (kg/h) /2 = 15.6 kg. To find out the minimum costs: 15.6 x 28.6 (tariff) = 446 rubles.

For a month (30 days):

15.6 (per day) x 30 = 468 kg. That means you use 22.3 propane tanks per month.

For a year (seven months):

7 x 468 (per month) = 3,276 kg or 156 cylinders.

Please remember that these calculations are for one model only. The meanings vary for each brand; you need to look them up in the documentation. See tables below:

And also for bottled gas:

Consumption is affected by the location of the device: floor or wall. Material of manufacture of the heat exchanger, type of gas burner, number of working days.

How to reduce costs

If you follow our recommendations in the domestic sphere, then you can save on using the boiler:

• Start with choosing a technique. It is considered the most economical. It saves up to 25% fuel, and efficiency reaches 100–110%. Of course, its cost is much higher, but, according to experts, it will quickly pay for itself. Pay attention to consumer reviews when purchasing. uses 20–25% more thermal energy. Therefore, if the room only needs heating, give preference to a single-circuit installation.
• Take care of wall insulation, install plastic double glazed windows. Heat loss through the roof can be easily determined by the build-up of icicles. The more heat goes away, the more icicles there are. In this case, close the roof, use special materials for insulation.
• Choose modern technology on automatic. It’s not for nothing that manufacturers install sensors, thermostats and regulators. This system works as a single organism, automatically regulating and adjusting the operation of the equipment to the conditions in the room. Timers and special modes allow you to maintain minimum values ​​during vacation or weekend. You can also select the “Winter - Summer” mode.
• Carry out routine maintenance once a year. Be sure to call a specialist for a technical inspection. Clean parts from blockages. Scale accumulations on the heat exchanger contribute to increased thermal energy use. Remove soot and soot from burner nozzles and clean the chimney in a timely manner.
• Install the heat accumulator (TA). This buffer capacity accumulates coolant and retains heat for a long time (like a thermos). Even when the boiler is turned off, the TA will supply liquid to the radiators. Using such a buffer allows you to save 20–30% of fuel.
• Don't choose maximum temperature. Set comfortable indicators, because against the backdrop of average monthly consumption, even 1–2 degrees matter.

This is how the cost of heating a living space is calculated. If you are not sure of the accuracy of the calculations, contact a specialist. He will take into account all the nuances and help you with the selection of economical equipment.

Design and principle of operation of the Baxi Eco Four boiler

Functions, control and safety

As with all models of fourth generation Baksi boilers, on front side The wall-mounted unit “Eco Four 24 F” has a control panel with an LCD display, which displays and sets settings and parameters, temperature in the heating circuit and DHW. In addition, they appear on it when malfunctions or malfunctions occur during the operation of the boiler.

The heating circuit of the Baxi Eco Four boiler can operate in two modes:

- traditional (30-85 °C);
— warm floor (30-45 °C).

Like the boilers of the “Main Four” series, all “Baxi Eco Four” devices incorporate weather-dependent automation that helps the boiler operate depending on the temperature outside the window. All you need to do is buy a sensor outside temperature, install and connect it to the boiler.

Buying and connecting a room thermostat will also help save money, because the operation of the boiler, in this case, will depend on the set air temperature in the house or apartment.

Today we left a review of the popular dual-circuit wall model boiler for heating - technical characteristics, device according to the operating instructions. Reviews from owners and specialists are quite contradictory, but the undoubted advantage of the EcoFor series devices is the presence in them of two separate heat exchangers, a brass hydraulic group and a Grundfos brand pump. Let's watch the video.

Owners of private houses or other premises always feel the need to reduce heating costs.

Autonomous heating systems, which require certain initial investments, can pay for themselves in a fairly short time and bring significant savings.

At the same time, an important condition for the effectiveness of the system becomes right choice heating boiler, on which the operating mode and performance of the system, the amount of fuel consumed and total costs for heating.

One of good options The choice is the Baxi Eco 4S 24 F gas boiler, which is capable of providing complete heat and hot water supply to a room of the appropriate size.

Let's look at it in more detail.

The Baxi company was founded in 1929, and has been developing and manufacturing heating products for more than half a century. During this time, valuable techniques were developed, high-quality and reliable models of heating installations were created.

In 2009, Baxi merged with De Dietrich Remeha to form industrial group BDR Thermea. Since that time, the company's capabilities have increased significantly, which has significantly affected the quality of its products.

Boilers Baxi Eco 4S 24 F are gas installations, providing coolant supply to heating systems (or heated floors) with parallel supply of hot water for domestic needs. The units are different high quality work, resistance to external influences and loads.

Most of the company's products are manufactured taking into account the specifics of Russian technological lines and climatic conditions, therefore boiler models are adapted to work with low pressures gas, with interruptions in the supply voltage in the network and other unstable indicators.

A useful function that is present in the list of boiler capabilities is frost protection, which ensures increased coolant circulation (or heating water- OV) according to the system.

The units have compact dimensions; the wall mounting type allows them to be installed in any convenient location. The parameters and technical characteristics of the installation make it possible to widely use it both in private homes and in office or public spaces.

Model features

The Baxi Eco 4S 24 F boiler has a copper primary heat exchanger, which demonstrates greater efficiency compared to stainless steel units.

The secondary plate heat exchanger, which produces domestic hot water heating, is a typical stainless steel plate device.

A convenient feature of the boiler is the coaxial chimney. It does not require a complex and time-consuming procedure for connecting to the central chimney; it is discharged through the adjacent outer wall in a horizontal position.

Pipe-in-pipe design allows for simultaneous flow fresh air into the burner along the outer part and remove combustion products through the inner part. This promotes cooling outer surface chimney, eliminating the risk of fire.

What functions does it have?

The set of boiler functions includes:

• Supply of coolant to the heating circuit simultaneously with heating of the hot water supply.
• Full protection with indication of switching on, presence or absence of flame, and prevention of freezing of pipelines.
• Self-diagnosis system, safety valve, protection circulation pump from blocking.
• Possibility of modulation (auto-adjustment) of the flame depending on external conditions.

NOTE!

Only the most basic functions are listed. Full list too large and does not differ much from the capabilities of other Baxi boilers.

Technical characteristics of a gas boiler

Consider the table technical parameters boiler Baxi Eco 4S 24 F:

Advantages and disadvantages of the model

To the advantages Baxi models Eco 4S 24 F is usually referred to as:

• High quality units that meet all necessary European and Russian standards.
• Environmentally friendly equipment.
• The ability to simultaneously heat and supply hot water to a home.
• Fully automatic operation mode, simplicity and accessibility of boiler operation control.
• Availability of self-diagnosis systems and protection of the boiler from various undesirable factors.
• Virtually silent operation that does not disturb the peace of the house's residents at night.

The disadvantages of boilers of this series are considered:

• The relatively high price of both the boilers themselves and spare parts for them.
• The need for regular paid maintenance.
• Dependence on power supply parameters, requiring the use of a stabilizer.
• The need to use filters or water softeners.

Both the advantages and disadvantages of Baxi Eco 4S 24 F boilers are common to most gas units similar level and can be attributed to design or assembly features.

His device

The main components that make up the boiler design are:

• Closed gas heating pad.
• A fan for supplying air to the combustion chamber.
• Primary (copper) and secondary ( stainless steel) heat exchangers.
• Circulation pump.
• Expansion tank.
• Three-way valve.
• Safety valves that relieve the pressure of the heating water or domestic hot water in the event of emergency situations.
• A control board, a system of sensors that send signals to it in a continuous mode.

The boiler operates according to the usual method characteristic of all similar designs. Using a circulation pump, the coolant is supplied to the heat exchanger, where it is heated to the highest possible temperature.

At the exit it is fed into three way valve, diluting hot OM with colder reverse flow in a given proportion, determined established regime heating After this, the prepared coolant is sent to the heating circuit.

Hot water is heated in a secondary (plate) heat exchanger and supplied to the distribution points. Closed chamber combustion improves quality internal air indoors.

To organize combustion in the required mode, air is supplied using a fan, which takes the required flow from the external compartment of the coaxial chimney.

For which rooms is it best suited?

Wall-mounted gas boilers are optimally suited for use in private homes or other premises of the appropriate size.

The specificity and set of functions make it possible to provide thermal energy and hot water supply to areas of up to 240 sq. m., which corresponds in size to a medium-sized two-story private house, store or other office space, public building.

Such boilers are not recommended for use in industry, although it all depends on the specialization of the workshop and the operating conditions of the heating circuit.

Startup instructions

After delivery and unpacking of the boiler, it is installed on the wall in a pre-designated location. It is necessary to choose a convenient site with the possibility of supplying communications, ease of access for maintenance and repair.

Then all relevant pipelines must be connected:

• Water.
• Direct and return pipeline heating circuit.
• Gas supply.

For the initial launch, perform the following steps::

• Connect power supply.
• Open the gas supply valve.
• By pressing the corresponding button, set the “summer” or “winter” mode.
• Using the “+” or “-” buttons to the right and left of the display, set the temperature of the coolant and hot water.

The burner will start and heating of the heating agent will begin.

The burner may not start when first turned on due to the presence of air in the system. The boiler will be blocked and the corresponding error code will appear on the display. By pressing and holding the “R” button for 2-3 seconds, the error is reset and the procedure is repeated until the expected result is obtained. It may take several tries.

Basic faults and troubleshooting methods

The sensor system constantly monitors the condition of all boiler components, signaling to the control board if any failures occur. A specific code appears on the display indicating a particular malfunction.

The full list of codes is much wider, but there is no point in citing it in its entirety. When one or another code appears, press the “R” button and hold it for 2-3 seconds until the error is reset. If it appears again, you should urgently call a specialist.

Owner reviews about the model

Let's consider the opinions of the owners of boilers of this series. Such information will help you look at the quality and capabilities of the units more realistically and pragmatically, without advertising or excessive enthusiasm.
