Boiler hearth device

Structurally, the Ochag boiler is designed in such a way that it can fit into any heating system. The front door is re-hinged according to need and opens either from the left or from right side. Two return lines, on the side and at the back, make it possible to supply the coolant from a convenient mounting side.

The Ochag boiler consists of:

Boiler body
Control automation
heat exchanger
Second circuit (if the boiler is double-circuit)
Safety system

In the lower part of the body, there is a combustion chamber, closed on the side and behind by sections of the water jacket. A heat exchanger is located above the combustion chamber. The high efficiency of heat transfer and heat exchange between the flue gases and the heat carrier is carried out due to the developed convective part of the heat exchanger, consisting of “flame” pipes.

In the upper part of the heat exchanger there is a smoke collector with a built-in draft stabilizer. In the front part of the smoke box there is a draft sensor, in the upper part of the smoke box there is a boiler outlet pipe. When installing the boiler into a chimney, it is necessary to coordinate the diameter of the outlet pipe with the cross section of the chimney. The technical parameters of the chimney must correspond to the technical parameters specified in the operation manual.

In the middle part of the smoke collector, there is a blocking plate to ensure stable operation of the device, regardless of weather conditions. The heat exchanger, complete with a smoke box, provides efficient work boiler without user intervention and without requiring manual adjustments. Stabilizer thrust contributes to the stable operation of the boiler with unstable draft.

A gas burner is installed in the combustion chamber of the apparatus Russian production Service Gas company. It consists of a front panel, burner pipes, safety sensors (flame sensor and draft sensor), and a SABK AT control unit.

Below, under the burner pipes, an easily removable distribution grate is mounted. Designed to supply secondary air for combustion

It is very important when installing the boiler in the room to ensure Free access air through the lower part of the boiler through the distribution grate to the burner pipes.

The boiler must be installed with a clearance at the height of the leg relative to the floor. The Ochag boiler is connected to the gas pipeline both on the left and on the right side. This allows you to make a block design. A temperature sensor is installed on the front panel, which indicates the temperature in the room.

The most common models

Buyers, most often, choose the following models of boilers "Ochag":

KST-16 M. This is a miniature model with one circuit (only heating needs are used). The power of the unit is 16 kW, it is designed for heating small houses with a total area of no more than 150 squares. Works on any kind solid fuel. If desired, the boiler can be retrofitted with electric heating elements. A feature of this model is the long breaks between refueling. Equipped with a system automatic control SABC, which is considered one of the most reliable and convenient.
KST-20 M. Single-circuit boiler, designed for space heating up to 200 square meters. This model is volatile, but it is distinguished by high functionality and ease of use.
KST-31.5 M. Single-circuit boiler recommended for use in rooms up to 300 square meters. It can work on all types of fuel (subject to the installation of additional equipment). When using solid fuel, the interval between loads is at least 8 hours.

KSTV-20 M. This is a double-circuit equipment used for both space heating and hot water. The models use steel heat exchangers. Can work on various types fuel. This model has a power of 20 kW, recommended for rooms of no more than 200 square meters.
KSTV-31.5 M. Double-circuit powerful unit with an open combustion chamber and steel heat exchangers. Suitable for use in rooms with an area of about 300 squares, it can work both on coal or wood, and on gas (after installing a gas burner).

How to understand labeling?

Heat generators "Ochag" are marked with digital and alphabetic designations. The numbers indicate the power of the boiler, that is, the KST-20 M model has a power of 20 kilowatts. Letter designations are deciphered as follows:

K - boiler (this letter is present in the marking of all models).
C - steel is used for the manufacture of the model, both the heat exchangers and the boiler casing are steel.
T - the model is designed to work on solid fuel.
G - the model can be used to work on gas, provided that a special burner is installed.
B - this letter is used to designate double-circuit models, that is, which work not only for heating, but also for supplying hot water.
M - modified models that allow the installation of electric heating elements.

A feature of parapet heating boilers is that they do not require the installation of an expensive chimney. The flue pipe comes with the heater. The device must be hung on the wall, after making a hole in it for the chimney pipe. Accordingly, the installation of the heater is possible only on the wall that borders the street. The chimney is designed in such a way that the wind does not blow into it.

Pay attention to the design of the chimney. .

There are two models in this line:

KSGZ - single-circuit;
KSGZV - double-circuit.

In one of our articles we have already explained principle of operation of a double-circuit boiler. The power of the units can be 10 and 12.5 kW. The boilers are equipped with SABK-AT automation, which is marked with the letters "AT", and Eurosit, which is marked with the letter "E". The combustion chamber of parapet boilers is of a closed type, while there is not a single volatile element in the design of the apparatus. Air for the flame enters through the smoke exhaust pipe from the street.

Due to the fact that the cross section of the nominal passage of pipes for connection to the heating circuit is 5 cm, the unit can operate in gravity system with natural circulation.

The casing of the boiler is insulated with mineral wool laminated with foil. At the same time, the housing can be easily removed so that you can get access to the heater elements for cleaning. The heat exchanger is protected from scale and salt, so it does not need to be cleaned, which greatly simplifies the operation of the unit. Sensors of draft and the presence of a flame on the wick are responsible for safety. The igniter of the unit does not need to be adjusted; it does not emit soot during operation. The efficiency is 89%. Warranty 2.5 years. How to clean the heat exchanger.

Solid fuel pyrolysis boiler Ochag

In this class of water-heating equipment, there is only one model with a power of 100 kW, which can heat 1 thousand square meters of space with a ceiling height of 2.7 m. Solid fuel boilers Hearth are marked with the letters KP. The main type of fuel is firewood with a moisture content of up to 30%, while wood trimmings and briquettes can be used as an energy carrier.

Solid fuel boilers Hearth is always white.

The furnace of the heater is large; logs 75 cm long are placed in it. On one full load, the device can work up to 8 hours. The design of the heater includes a fan and a control unit, which are powered by the mains. You can set the required temperature of the coolant, which will be maintained due to the intensity of the fan rotation. During the laying of firewood in the firebox, the fan automatically turns off.

Characteristics of the pyrolysis boiler Hearth:

Efficiency is only 85%;
the volume of water in the unit is 440 l;
furnace volume 240 l.

The heater weighs 1.4 tons without taking into account the coolant. Installed on the floor. It requires a conventional chimney with an internal section of 300 mm, since the diameter of the outlet pipe is 280 mm. The minimum height of the chimney is 5 m. To prevent the formation of condensate, the flue gas pipe must be insulated in areas that run in an unheated room and on the street.

Universal floor boiler Ochag

Universal heaters can operate on both solid fuel and natural gas. It can be fired with wood, briquettes and coal. This is convenient in areas where there are interruptions in gas supply. Also, these units are installed when there is still no central gas pipeline, but it should appear in the near future, and you need to heat the house now.

There are two modifications in the line - these are KSTG and KSTGS. They differ in the type of installed automation and the color of the case. The KSTG line is produced with SABKT-ZS-RD and SABKT-ZD automatics, the body is completely white. KSTGS models are equipped with SABK-8-50S-RD and SABKT-8-50T automatics, white casing with red inserts. All universal heaters are independent of the mains.

In fact, the temperature of the battery in the apartment according to the norms depends on the weather. The main thing is that the degree of heating of the air meets the standard.

About what is considered a normal temperature in an apartment in winter is written.

General specifications:

the presence of a DHW circuit;
Efficiency on solid fuel 73%, and on gas 87%;
the temperature of the coolant is regulated in the range from 50 to 90 degrees.

In addition to automation, the KSTG and KSTGS models, with equal power, differ in the volume of coolant in the boiler and the size of the furnace. For example, a 10 kW KSTG heater holds 34 liters of coolant, the volume of the furnace is 25 liters, and in a KSTGS - 40 liters and 31 liters, respectively.

A little about the installation of boilers

Installing solid fuel boilers is not the most difficult task. Basic system requirements:

It is necessary to ensure the removal of combustion products, that is, to connect the boiler to the chimney.

Advice! The boiler must be connected to a chimney made of two pipes, between which a heat-insulating material is laid. This is necessary to prevent the formation of condensation. The height of the pipe is determined depending on the power of the model (this parameter is indicated in the instructions).

Only water can be used as a heat carrier in a heating system with a solid fuel boiler. The use of other types of coolant is excluded.
An expansion tank should be provided at the top of the system circuit. The use of boilers of this type in closed systems is prohibited.

To install boilers with an open firebox, it is recommended to equip a separate room. As a rule, it is located in the basement or in the basement. The boiler room should be equipped in accordance with the requirements of fire and sanitary safety.

When installing the boiler, the following rules must be observed:

They put the boiler on a solid, even base (most often they use a concrete screed).
The boiler must not be placed close to the wall. The distance from the wall to the back wall should not be less than half a meter, the distance from the front wall should be more than 1.25 meters.
The floor and walls in the boiler room should be treated with a vapor-and-gas-tight coating with a fire resistance index of at least three quarters of an hour.
A hole should be made in the ceiling or wall of the boiler room for the chimney to exit. The inner diameter of the chimney pipe must be equal to the size of the boiler outlet.

So, the solid fuel boiler hearth is a modern heat generator, which, if necessary, can be converted to run on gas. The equipment is distinguished by its quality factor, the boiler is convenient to use, since the intervals between fillings of fuel are quite large.

general information

Modern solid fuel boilers have gone far from their "ancestors". Today, a boiler is a device that provides long-term combustion of fuel through the use of the pyrolysis effect. Thanks to this, it was possible to significantly increase the efficiency of fuel technology.

In addition, modern boilers are equipped with a device for adjusting the heating power and combustion intensity. Thanks to this, the owners have the opportunity to choose the optimal temperature regime in the house, saving fuel.

Principle of operation

The boiler is divided into two parts:

the upper compartment is used for laying fuel (coal or firewood);
the lower compartment is a combustion chamber, into which air and gaseous products of the pyrolysis reaction are supplied, passing in the upper chamber.

Combustion of fuel takes place at extremely high temperatures, this process ensures the release of gas from organic fuel, as well as a large amount of heat.

Floor standing gas boilers Ochag KChG

Description

Heating household boilers cast iron KCHG are designed for heating residential buildings with a total area of up to 700 m2 with a ceiling height of 2.7 m. These heating boilers operate on low-pressure natural gas in automatic mode according to the temperature of the coolant.

When using KCHG cast-iron gas boilers with a cast-iron heat exchanger in heating systems, the following is achieved:

energy saving (gas consumption is reduced by up to 30%) due to the built-in gas pressure stabilizer;
reduction of harmful emissions into the atmosphere;
increasing the accuracy of temperature control in the room.

Household cast-iron gas boilers KCHG operate in automatic mode according to the specified temperature of the coolant in the heating system, have 5 degrees of protection in case of emergency:

when the coolant overheats in the heat exchanger;
when the flame goes out on the pilot burner;
in the absence of traction;
when the gas pressure in the network drops below the minimum allowable value;
at elevated coolant pressure.

These floor standing cast iron boilers use a high efficiency cast iron heat exchanger with an acicular convective heating surface, heat resistant slotted stainless steel main burners. The gas pressure stabilizer built into the gas block ensures uniform combustion of the gas-air mixture on the main burners with a constant heat output, regardless of the gas pressure in the network, without requiring adjustment.

The draft chopper (draft stabilizer) equalizes the air pressure in the suction zone into the ejector of the main burners and near the exit of the gas-air mixture from the slotted grooves with the main burners open, ensuring stable combustion of the gas-air mixture at a constant vacuum in the furnace without adjustment, and also excludes blowing out of the pilot burner during short-term overturning traction.

The main burners are placed evenly under the heat exchanger, creating a uniform thermal field in the furnace volume, which eliminates the formation of local overheating zones of the heat exchanger and its destruction.

Advantages of cast iron boilers KCHG:

The design and small dimensions of the heating boiler allow it to harmoniously fit into any interior of the room.
Modern design and technological developments used in this cast-iron boiler make it easy to maintain and operate.
Complete energy independence of the domestic boiler from external sources of electricity.
Possibility of work at the lowered (up to admissible limits) pressure of gas.
The increased strength of the heat exchanger eliminates mechanical damage to the cast iron gas boiler when used in closed heating systems (with membrane expansion tank).
To heat water for domestic needs, a boiler is connected to the heating boiler.
Does not require adjustment for atmospheric changes.

Choosing a gas boiler Hearth

Finally

Before purchasing this or that model of heating equipment, you should consider whether you need hot water in addition to heating in the house. The design may be volatile or independent of the supply of electricity. Some installations have a chimney or are devoid of this unit.

The best gas boiler "Ochag" is the one that is quiet, economical, convenient and easy to use, as well as safe. More in demand today are dual-circuit options. Wall-mounted have a smaller heating area, but are more compact. Before you buy a gas boiler "Ochag", you must calculate its power. This parameter should be taken with a margin, because then the equipment will not work for wear.

Floor-standing heating boilers of the KSG / KSGV "LUCH" series are modern, efficient and safe equipment that will allow you to organize a reliable, non-volatile heating system in any premises ranging from 80 to 500 m². Russian-made gas boilers "LUCH", depending on the configuration, can operate on both natural and liquefied gas.

Floor-standing gas boilers "LUCH" are equipment with an open combustion chamber, operate in open and closed heating systems, maintain natural circulation of the coolant, operate in heating networks with forced circulation, do not require additional installation of smoke exhausters and fans.

Depending on the purpose, the series is divided into:

Single-circuit gas floor boiler (KSG marking). This type of equipment is intended only for organizing a heating system for a house (apartment, summer cottage, garage, industrial premises, etc.). Hot water preparation requires additional equipment (gas instantaneous water heaters, boilers, indirect boilers).
Gas floor double-circuit boiler (marking KSGV). This type of equipment will allow not only to heat the house, but also to organize a system for preparing hot water for domestic needs. The design provides for two heat exchangers: for the heating system and hot water separately.

Gas burner device (GGU)

The boilers of the TGA plant are equipped with one of the most reliable GGUs; in terms of reliability, the KSG / KSGV “LUCH” gas burner device is superior to its counterparts. Before being fed to the burner, the gas passes through the automatic filter mesh. The filter allows you to trap particles of dust and debris, protecting the burner jets from clogging. The non-volatile gas boiler "LUCH" is equipped with a low-flame carpet-type burner - one of the most efficient. The number of jets in it is increased, and the diameter, on the contrary, is reduced. This allows to reduce gas consumption and at the same time ensure uniform heating of the combustion chamber and heat exchanger, which increases the efficiency of work and increases the reliability of the boilers of the TGA plant.

Automation control and security

Russian-made gas heating boilers "LUCH" are equipped with non-volatile, reliable, modern automation. All automation elements use mechanical drives that are triggered by changes in gas pressure, water, temperature, and the state of safety sensors. The automation used has a built-in regulator, which allows you to smoothly and accurately modulate the fuel supply to the burner and instantly stop it under certain conditions. In addition, the regulator allows you to compensate for pressure drops in the main gas, which are not uncommon in real operating conditions.

Automation allows you to implement 5 levels of security. Safety shutdown is activated in the following cases:

Blockage or lack of traction;
Flame extinction on the pilot burner;
Stopping the gas supply;
Overheating of the coolant in the system;
Attempt to restart.

Floor-standing boilers of the TGA plant are produced in a wide range of capacities. In the product line, you can find boilers from 8 to 50 kW, which allows you to choose the best option for heated areas of various sizes. Depending on the power, gas heating boilers "LUCH" are equipped with safety automatics of the following types:

8-20 kW - TGV307 (similar to EUROSIT630);
25-30 kW - 710 MINISIT;
40-50 kW - 820 NOVASIT.

In models with low power, the thrust sensor is located on the front panel. Due to this, it was possible to reduce the length of the electrical circuit, and, consequently, the energy loss to overcome the resistance. The production of gas boilers is constantly being improved, changes are made to the design to improve efficiency, safety, ease of use and maintenance.

Design features

Russian boilers "LUCH" KSG / KSGV 8-50 operate on the principle of natural draft. Good, stable traction in any weather throughout the season was achieved thanks to the traction stabilizer and the chipper in the design of gas heating equipment. The stabilizer with a baffle is located in the upper part of the boiler above the heat exchanger.

In powerful models (25-50 kW), the flue is brought back. The flue outlet on the gas duct can be installed both upwards and backwards for ease of installation and compact placement of the boiler. If necessary, the cover with a nozzle can be easily removed and installed in the desired position. The diameter of the chimney complies with GOST and the power of the unit, which allows you to maintain the efficiency of the equipment at a high level and extend its service life.

Any of the boilers of the KSG/KSGV "LUCH" series can be switched from natural gas to liquefied gas and vice versa. To do this, you only need to purchase a translation kit, supplied separately. The procedure for transferring from liquefied gas to natural gas (and vice versa) is carried out with minimal intervention in the design: the jets, the igniter tube are replaced and the automation is adjusted.

It must be remembered that any work on the installation, maintenance and re-equipment of gas boilers should be carried out only by certified gas service specialists.
