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.

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 rear 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. At the same time, it is missed almost twice more water, 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 insulation materials are not included in the factory supply.

PTVM series boilers are designed to produce hot water with a temperature of up to 150 `C in free-standing boiler houses for use in heating, ventilation and hot water supply systems for industrial and domestic purposes and at thermal power plants.
  Hot water heating boiler PTVM- peak heating water heating gas and oil, i.e. can be used to cover the peak portion of the heat load curve.
  Initially it stood for “peak heating water heating with fuel oil”, but later in Moscow all these boilers were switched to gas.
  PTVM series boilers have the following modifications: PTVM-30, PTVM-50, PTVM-60, PTVM-100, PTVM-120 and PTVM-180, according to the increasing heat output (Gcal/hour).
  All PTVM boilers are basically similar in design, have a tower layout and are made in the form of a rectangular shaft, in the lower part of which there is a completely shielded chamber firebox.
  Boilers are assembled either from the same or from similar elements, which ensures the unification of their production. The design of these units allows semi-open installation. In this case, only the lower part of the boiler is enclosed in the room, where burners, fittings, automation and blower fans are located. This reduces the cost of constructing a heating station building and creates convenience for summer repairs.
  For all boilers except PTVM-180, it is possible to install them both with a steel chimney directly supported by the boiler frame, and with a free-standing reinforced concrete or brick chimney.
  PTVM-30 And PTVM-50 are installed at district thermal stations (RTS). PTVM-50 are the main equipment of the RTS of the Moscow fuel and energy complex (at least until 2000). More powerful PTVM-100 and PTVM-120 are installed at both RTS and CHP plants. And finally, powerful PTVM-180 only at thermal power plants.
