PTVM boilers with capacity: 30; 50; 100 MW.

Water heating boilers PTVM are intended for installation in heating boiler houses as the main source of heat supply to obtain hot water temperature 150°C, used in heating systems, hot water supply of industrial and household use and at the thermal power plant.

Technical characteristics of PTVM-30 boilers

The boiler is a direct-flow boiler with a U-shaped closed arrangement of heating surfaces. The boiler furnace is completely shielded by pipes 060x3 mm, located with a pitch of S = 64 mm, and is equipped with six gas-oil burners MGMG-6, installed counter-clockwise on the side walls.

Convective heating surfaces are located in a convective flue with side walls, shielded pipes 083x3.5 mm, which are risers of convective sections made of pipes 028x3 mm. The rear wall of the convective flue is shielded with 60x3 mm pipes. The pipe system of the PTVM-30 boiler rests on a frame frame at an elevation of 5.14 m.

The range of boiler load regulation is 30 -100% of the nominal output. The heating output of the boiler is changed by changing the number of operating burners. The water flow through the boiler must be maintained constant; when the heat load changes, the difference in temperature of the water at the inlet and outlet of the boiler changes.

By agreement, boilers can be equipped with any foreign or domestic gas burners corresponding performance.

Boilers operating on fuel oil can be equipped with a gas pulse cleaning device (GCP) to remove external deposits from the pipes of convective heating surfaces.

Convective heating surfaces located in a convective flue with side walls, shielded pipes Ø83x3.5 mm, which are risers of convective sections made of pipes Ø28x3 mm. The rear wall of the convective flue is shielded with pipes Ø60x3 mm.

Pipe system of the boiler PTVM-30M rests on the frame frame at 5.14 m.

Load control range boilers% of rated output. The heating output of the boiler is changed by changing the number of operating burners.

Water flow through the boiler must be maintained constant; when the heat load changes, the temperature difference between the water at the inlet and outlet of the boiler changes.

Oil fired boilers, can be equipped with a gas-pulse cleaning device (GCP) to remove external deposits from convective surface pipes for heating.

Technical description of hot water boilers PTVM-50, PTVM-100, PTVM-120

Boilers PTVM-120 (KV-GM-139.6-150) have a tower layout: above a vertical combustion chamber rectangular shape the convective heating surface is located.

The combustion chamber is screened with pipes Ø60x3 mm with a pitch of 64 mm and is divided in two by a double-light screen made of pipes Ø60x3 mm with a pitch.

The convective heating surface of the PTVM-120 (KV-GM-139.6-150) boilers consists of eight packages, assembled from U-shaped screens from 28x3 mm pipes. The side walls of the convective flue are covered with pipes 83x3.5 mm, with a pitch of 128 mm, and are also risers for convective half-sections.

The pipe systems of the PTVM-120 (KV-GM-139.6-150) boilers are suspended from the frame by the upper collectors and expanded downward.

The design of the PTVM-120 (KV-GM-139.6-150) boilers allows semi-open installation - only the lower part of the boiler is enclosed in the room, where the burners, fittings, automation and blower fans are located, which significantly reduces the cost of constructing the heating station building and creates conveniences for summer repairs.

For boilers PTVM-120 (KV-GM-139.6-150) it is possible to install them both with steel chimney, directly resting on the boiler frame, or with a free-standing reinforced concrete or brick chimney.

The PTVM-120 (KV-GM-139.6-150) boilers are equipped with sixteen MGMG-8 gas and oil burners, located in pairs on the front and back walls eight pieces on each side. Each burner is equipped with an individual blower fan.

By agreement with Biysk Boiler Plant OJSC, PTVM-120 (KV-GM-139.6-150) boilers can also be equipped with foreign and domestic gas burners of appropriate capacity.

To clean the convective part of PTVM-120 (KV-GM-139.6-150) boilers, it is washed with network water using special nozzle-type nozzles. Water consumption depends on the boiler operating mode: in winter period A 4-way water circulation scheme is used, in summer period- two-way (peak). With a 4-pass scheme, water from the heating network is supplied to one lower collector and sequentially passes through all elements of the heating surface of the boiler, performing lifting and lowering movements, after which it is discharged through the lower collector to heating network. In a two-pass mode, water enters simultaneously into two lower collectors and, when heated, is removed into the heating network. In this case, almost twice as much water is passed through, because it enters the boiler with more high temperature: 110°C instead of 70°C.

PTVM-120 (KV-GM-139.6-150) boilers have lightweight lining and frame thermal insulation. Masonry and insulating materials are not included in the plant’s supply.
