1. KVA boilers (unsupervised).
2. KV-GM boilers (power from 4.65 MW).
3. Boilers KVE, DSEV, DEV-boilers of the E, DSE, DE series manufactured in hot water mode.

Explanation of the designation:
KV - hot water boiler
GM - type of fuel - gas, fuel oil, liquid. fuel.

KVA series boilers - liquid fuel boilers of this series are separated into a separate block due to significant differences in the design of boiler cells, modular boiler systems, and in general the production process of hot water boilers looks different.
Let's start with water-heating water-tube boilers of the collector type; the structure of these boiler units is clearly visible in the drawings indicated above. Everything is as usual: the combustion chamber goes into the convective part, etc. These boilers are interesting because they are not included in the supervised list because pass both pressure (less than 0.6 MPa) and temperature (less than 115 `C), but at the request of the customer they allow you to increase these characteristics.
Boilers of this brand are intended for heating and hot water supply of industrial, public and residential buildings. They operate on gas or liquid (diesel) fuel. Depending on the type of fuel, boilers are equipped with gas, liquid fuel or combined burners.
  Water heating boilers of the KVGM series are designed to produce hot water with a pressure of 0.6 (6.0) MPa (kgf/cm2) and a nominal temperature of 95 -115 `C.
  Boiler type: water-tube, horizontal with forced circulation.

2. KV-GM boilers.

Boilers of the KV-GM series - water-heating gas-oil boiler.
Boilers of the KV-GM (KV-GM) series are designed for heating, industrial and technological needs and the production of hot water with a nominal temperature at the boiler outlet of 150°C, used in industrial and domestic facilities. The boilers are designed to operate in a closed heating system with forced water circulation.
Boilers KV-GM-4.65-150 (KV-GM-4-150), KV-GM-7.56-150 (KV-GM-6.5-150) These are water-tube boilers of a horizontal arrangement of a collector type consisting of a pipe system.
Boilers KV-GM-11.63-150 (KV-GM-10-150); KV-GM-23.26-150 (KV-GM-20-150), KV-GM-35-150 Boilers of this type consist of two blocks, combustion and convection, supplied in bulk or assembled.
  Boiler type: water-tube, horizontal with forced circulation.
KV-GM boilers, and indeed KV collector-type boilers in general, are distinguished by the following:
When supplied assembled or in blocks, installation time and cost are reduced, and when supplied in bulk, additional technological openings are not required;
interchangeable components and parts used in this factory series of boilers allow them to be used on similar hot water boilers
boilers are durable, repairable, easy to maintain, have access for inspection, repair and cleaning of pipes
The boiler design is designed to operate in the Far North and areas with seismicity up to 9 points inclusive.

Historical reference

The Biysk Boiler Plant has mastered the production of boilers of the KV-GM series with a capacity of 4.0; 7.56; 11.63; 23.26 and 35 MW and pressure 1.0; 1.35 and 2.25 MPa since 1959.

In the late 60s and early 70s of the 20th century, a sharp industrial rise and rapid development of housing construction began in the country. There was a growing need to quickly increase thermal capacity, both at existing thermal power plants and at the construction of new heating plants.

The optimal solution to this problem was the installation of relatively inexpensive peak water heating boilers, included in the heating network and designed to cover short-term peaks in heating load, as well as as the main source of heat supply throughout the heating season and to cover the need for summer hot water supply.

To achieve this task, a standard size range of a series of peak heating hot water boilers with a heating capacity of 30, 50, 100 and 180 Gcal/h for burning gas and fuel oil was selected.

Technical and working designs were developed by VTI, the Moscow branch of the Orgenergostroy Institute and BiKZ. Since 1959, the Biysk Boiler Plant began producing boilers with a capacity of 100 and 180 Gcal/h. Subsequently, the production of this series of boilers was transferred to other boiler plants of the USSR, as well as to Czechoslovakia and Romania.

Simultaneously with high-power boilers, according to the patent of BiKZ, TsKTI and DKZ, a series of water heating boilers of the KV-GM type with a heating capacity of 10.0 was developed; 20.0; 30.0; 50.0 Gcal/h. The boilers were mass-produced and produced in large quantities.

Currently, the Biysk Boiler Plant produces boilers of the KV-TS, KV-GM and PTVM series, as well as boiler and auxiliary equipment for them: fans, smoke exhausters, economizers, water treatment equipment.

Water-heating water-tube boilers of the KV-GM series are designed for heating and hot water supply of housing, communal and industrial facilities. A boiler is a heating unit that heats water from heating networks directly or through heat exchangers. The boiler is designed to heat water with temperature curves of 95\70,115\70,150\70 with a constant flow of water through the boiler within the load control range. The load control range is 30–100%. Boilers operate on natural gas, diesel fuel, fuel oil, and solid fuel.

Design

The KV-GM boiler is a water-heating water-tube gas-tight boiler, with a horizontal or vertical arrangement of heating surfaces. According to the movement of flue gases, boilers are single-pass (span), two-pass, three-pass. The boiler design includes a combustion chamber and a convective heating surface located behind the combustion chamber. The combustion chamber of the boiler and the convective part are shielded by membrane panels assembled from pipes with a diameter of 51x4.0 mm, with welded spacers that ensure gas tightness of the boiler for operation under pressurization. The convective heating surface consists of a certain number of packets. Each package is assembled from horizontally or vertically located screens made of U-shaped pipes with a diameter of 28x3 mm. Drains and air vents are made of pipes with a diameter of 28x3 mm. The boiler design provides the necessary hatches and peepholes for operating the boiler. The gas-tight design of the boiler allows the use of lightweight thermal insulation 50 mm thick with decorative cladding. It is also possible to use boilers for working with vacuum.

Burner devices

KV-GM boilers are used with modern automated burner devices from leading European and Russian manufacturers, approved for use by the boiler manufacturer.

Advantages

  Apparently the KVGM boiler is a further development of the boiler PTVM. At least it is newer, since in Moscow the PTVM has been installed since 1958, and the KVGM since 1972.
  It would be interesting to watch the discussion among specialists on the comparative characteristics of the PTVM and KVGM boilers.

Boilers of the KVGM type were once produced in the Soviet Union by the Dorogobuzh Boiler Plant in large series. These boilers are still produced today by several enterprises.
  This design has proven its right to life both from a technical point of view and from the point of view of the possibility of its implementation in the heat and energy market.
  However, boilers operating for a long time are exposed to corrosion and erosion, resulting in the need to replace individual elements. In some cases, modernization and reconstruction of boilers of this type makes it possible to extend their service life for an indefinitely long time.
  On the page Repair and modernization of PTVM and KVGM boilers a list of organizations performing similar work is presented.

An even more advanced series of boilers of this type are boilers of the brand
