The main elements of the KV-GM-4.65-150 boiler are: a pipe system that combines a combustion chamber and a convective heating surface and a gas-oil burner.

Boilers KV-GM-4.65-150 and KV-GM-7.56-150 have a single profile, and differ only in the depths of the combustion chamber and the convective flue. The combustion chamber has a horizontal layout, shielded by pipes Ø 60x3 mm, included in the collectors Ø 159x7 mm.

The convective heating surface, located in a vertical, fully shielded gas duct, consists of U-shaped screens made of pipes Ø 28x3.

The KV-GM-4.65-150 boiler is equipped with one gas-oil burner RGMG-4. The burner is installed on the air box of the boiler, which is attached to the shield on the front screen. Maintenance of the burner, its description and technical characteristics are given in the documentation supplied with the burner.

Oil-fired boilers are equipped with a gas-impulse cleaning device (GIP) to remove external deposits from the pipes of the convective heating surface. The principle of operation of gas-pulse cleaning is based on the impact on external deposits of directed shock and acoustic waves generated due to the explosive combustion of a gas-air mixture.

The boiler KV-GM-4.65-150 does not have a supporting frame. The pipe system has supports welded to the lower manifolds. The supports located at the junction of the convection and combustion chambers are fixed.

The KV-GM-4.65-150 boiler is made in a lightweight pipe lining and is supplied in one transportable unit or in bulk.

Technical characteristics of the boiler KV-GM-4.65-150

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

Deciphering 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 unit due to a significant difference in the design of boiler cells, modular boiler plants and, in general, the production process of hot water boilers looks different.
Let's start with collector-type water-heating water-tube boilers, the arrangement of these boilers is clearly visible in the drawings indicated above. Everything as usual, the combustion chamber passes into the convective part, etc. These boilers are interesting in that they are not included in the supervised list. pass both in terms of pressure (less than 0.6 MPa) and temperature (less than 115 `C), but at the request of the customer they allow to increase the data and characteristics.
Boilers of this brand are designed for heating and hot water supply of industrial, public and residential buildings. Operate on gas or liquid (diesel) fuel. Depending on the type of fuel, the boilers are equipped with gas, liquid fuel or combined burners.
Hot water 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.
Type of boilers - water tube, horizontal with forced circulation.

2. KV-GM boilers.

The boilers are designed to work in a closed heat supply 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 layout 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 of furnace and convection, supplied in bulk or as a set.
Type of boilers - water tube, horizontal with forced circulation.
KV-GM boilers, and indeed KV collector-type boilers, are distinguished by the following:
When supplied as an assembly or in blocks, the 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 their use on similar boilers
boilers are durable, maintainable, easy to maintain, have access for inspection, repair and cleaning of pipes

History 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 upsurge and the rapid development of housing construction began in the country. There was a need for a rapid increase in thermal capacities, both at existing thermal power plants and at the facilities of new heating plants.

The optimal solution to this problem was the installation of relatively inexpensive peak hot water 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 entire heating season and to cover the need for summer hot water supply.

To implement the task, a standard range of a series of peak cogeneration hot water boilers with a heat output of 30, 50, 100 and 180 Gcal/h for burning gas and fuel oil was chosen.

Technical and working projects were developed by VTI, the Moscow branch of the Institute "Orgenergostroy" 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 hot water boilers of the KV-GM type with a heat output 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 auxiliary boiler 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 and communal and industrial facilities. The boiler is a heat unit that heats the water of heating networks directly or through heat exchangers. The boiler is designed for heating water with temperature curves 95\70,115\70,150\70 with a constant water flow through the boiler in the load control range. The load regulation range is 30–100%. Boilers operate on natural gas, diesel fuel, fuel oil, 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. Boilers for the movement of flue gases are single-pass (span), two-pass, three-pass. The design of the boiler 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-in spacers, which ensure the gas tightness of the boiler for pressurized operation. The convective heating surface consists of a certain number of packages. Each package is assembled from horizontally or vertically arranged screens made of U-shaped pipes with a diameter of 28x3 mm. Drainages and air vents are made of pipes with a diameter of 28x3 mm. The design of the boiler provides the necessary hatches and peepers for the operation of the boiler. The gas-tight design of the boiler allows the use of light thermal insulation 50 mm thick with decorative trim. It is also possible to use boilers for operation with vacuum.

Technical characteristics of water-heating gas-oil boilers KVGM

Boilers of the KVGM type were once produced in the Soviet Union by the Dorogobuzh boiler plant in large series. These boilers are produced to this day by several enterprises.
This design has proved 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 power market.
However, boilers operating for a long time are exposed to corrosion and erosion, as a result of which it becomes necessary to replace their individual elements. In some cases, the 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 that carry out such work is presented.

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