The KChM boiler is a reliable, simple and popular piece of equipment. This equipment can operate on different fuels. The design feature allows for quick repairs - the damaged section is replaced with a new one. This is the main difference from steel boilers, which can be difficult to repair.

Who is the manufacturer

Cast iron boilers KChM are produced by Kirov Plant OJSC. This enterprise has been operating for more than two centuries. Currently, the plant is part of a production holding and produces cast iron products. And KChM heating boilers are one of the activities of the enterprise.

Decoding

The abbreviation KChM stands for modernized cast iron boiler. Let's consider, for example, the solid fuel boiler KChM-5-K-03 M(M1), its name carries the following information:

• K – combined;
• 03 – standard design;
• M - modernized with a single door for scooping and ash;
• M1 – modernized with different doors.

Construction of KChM boilers

This equipment is made of cast iron, which is durable and reliable, and this material is not afraid of corrosion and does not burn out like steel, from high temperatures. The weak point is sudden changes in temperature, as a result of which cracks can form.
Structurally, the heating surface is a package of sections made of cast iron. The chimney is attached to the last section and the boiler is connected to the heating system there.

On the front side there is an inspection hatch for cleaning the chimney and a number of doors (for loading fuel, for cleaning the ash pan and for screwing). To avoid heat loss, the unit is covered with thermal insulation, usually mineral wool, which can withstand high temperatures and does not pose a risk to human health.

A metal jacket coated with paint is placed on top. The draft is adjusted manually using slide valves. The boiler body is equipped with a number of instruments for monitoring operation. In the heating zone, for example, a thermometer is mounted to measure the temperature of the coolant.

Advantages and disadvantages

Boilers for solid fuel KChM have a number of advantages:

• material of manufacture – cast iron;
• wide range of heating output: from 21 to 80 kW, which is possible thanks to the sectional design;
• small dimensions, which is convenient when placed in a small room;
• possibility of modification to operate on other types of fuel;
• non-volatile;
• no special requirements for traction;
• easy operation and maintenance;
• unpretentious to fuel quality;
• possibility of restoration;
• Russian production, which is convenient when purchasing spare parts;
• long service life (over 25 years), which is ensured by high-quality parts;
• low cost compared to analogues.

However, it is worth noting the disadvantages:

• high fuel consumption;
• coefficient useful action on average about 78%, which is lower than that of analogues;
• low efficiency leads to increased waste generation and frequent cleaning;
• strict requirements for the quality of the chimney.

The efficiency depends directly on the quality of the fuel. It is most effective to use AM grade anthracite coal or damp firewood - up to 20%. Coal consumption is low.

Main settings

The technical characteristics of the KChM depending on the heat output are as follows:

Installation and operation rules

When installing a boiler, it is necessary to fulfill certain requirements related to fire safety. This will increase the service life of the solid fuel boiler and ensure safety and comfort.
When installing the boiler in a suitable room, it is important to maintain the distance from the unit to the walls: from the back surface to the wall at least 250 mm, to the side surfaces at least 100 mm.

To ensure access to the rear surface of the boiler during installation and maintenance, it is necessary to maintain a distance of at least 400 mm from one side. A free space of about 1 sq.m. is provided in front of the boiler to ensure easy loading of fuel and cleaning of the ash pan.

The heating installation is placed on a reliable base, finished with fire-resistant materials, or on a platform.
The fuel is placed at a distance of 400 mm from the boiler.
The coolant is used prepared, without impurities, to avoid the formation of deposits, which can reduce the service life.
The equipment is suitable for operation in systems with both natural and forced coolant circulation.

It is important to protect the boiler from overheating when the water temperature has reached the maximum value and the fuel continues to burn.

This phenomenon can be avoided by using: a thermostatic draft regulator, using a cooling heat exchanger, a switching valve or installing a heat storage tank.

Malfunctions

During operation, characteristic malfunctions of the CFM may be observed.

Why a solid fuel device?

A similar solid fuel boiler KCHM5 is sometimes also called a heat generator. It is these generators that are causing wild demand among owners of estates, dachas, private houses and cottages. In such buildings, most often there is no access to a central heating system, which means there is a threat of freezing.

Heat generators are a device that can be used literally in any room; the quality of heating in it will be the same, regardless of the fuel:

• Coal;
• Firewood;
• Wood processing waste (solid fuel), that is, pellets;
• Peat briquettes;
• Fuel pellets.

Main gas pipelines are accessible only to some houses and streets, while the rest have to use similar solid fuel boilers KCHM-5. This will cost the owner much less than connecting to shared network, and technically it is much easier to do.

Liquid fuel and electric boilers KCHM are not entirely economically profitable, this fuel is constantly rising in price, and who knows how much electricity or diesel will cost in 2-3 years. Better be sure tomorrow and install a really high-quality and reliable solid fuel boiler KCHM-5.

Design and diagram of the heating device

The solid fuel boiler KCHM5 is known for being made from special cast iron sections. Cast iron as a material is the most durable and resistant to temperature changes. It was chosen as the main one due to its high strength qualities and resistance to corrosion. The heat capacity that cast iron has is also high, meaning it can hold heat for a long time. These properties are perfect for efficient work solid fuel boiler KCHM-5.

It has long been established that solid fuel boilers KCHM 5, the construction of which is made of cast iron, serve without problems for 50 years. But it should be noted that although it is the strongest material, it still has weaknesses - too sudden and frequent temperature changes make it fragile and susceptible to corrosion. Proper use and operation of solid fuel heating equipment is the key to long and efficient home heating.

Another important nuance is that this unit is called solid fuel, because it can operate on two main types of fuel:

• Natural gas;
• Diesel fuel.

The internal design and system of such a device is presented below with all the smallest elements.

Which solid fuel boiler to choose?

Solid fuel boilers KCHM 5 can have different designs and structures, but there are two most common types of such generators that you should pay attention to:

• Solid fuel boilers KCHM micro;
• Solid fuel boilers KCHM-5.

The cast iron solid fuel boiler is manufactured in Kirov at the famous Kirov Plant OJSC. Its advantage is that it uses water as a coolant, and all thanks to the fact that its base is cast iron. This allows you to use water for many years without damaging the condition of the device.

Its power can be different and ranges from 20 to 80 kW, such indicators make a solid fuel boiler universal, because the area that it can heat with such power is 200-800 square meters. In addition, for large areas the plant produces a special cast iron solid fuel boiler called “Universal”.

Solid fuel boilers KCHM micro are a modern and reliable type of device that have a power of about 14-17 kW and can heat large areas.

Advantages of solid fuel boilers KCHM

One can talk forever about the advantages of these types of heat generators.

But the most outstanding advantages are the following:

• The quality guarantee of solid fuel boilers KCHM micro and KCHM-5 is at least 25 years.
• The models have a draft regulator, which sets the necessary air intake into the firebox.
• Heating area standard model– up to 800 square meters.
• Long burning solid fuel, economy and efficiency.
• Modern design.
• Ease of use.
• Easy to install, repair and configure.
• Decent power, not inferior to competing companies.
• Possibility of switching to another type of fuel.
• Efficiency is about 77%.

These are just a few of the advantages of micro and KCHM-5 cast iron boilers.

It is also worth noting the possibility of switching to another fuel. To switch to natural gas from additional equipment, you only need a burner and SABC devices. You can also buy a diesel burner for a solid fuel unit. Switching will take no more than 20-30 minutes, you can do the setup yourself, because operating the equipment is quite simple.

The solid fuel boiler KCHM-5 is produced in series with sections ranging from 3 to 9, while the micro boiler KCHM has 3-4 sections. It is designed for smaller areas and has a comparatively lower heating power. But if the consumer needs equipment that will work on large territory, then sections can be added to order; the power can increase on the KCHM-5 model to 110 kW.

Installation of a solid fuel boiler

>There are several important factors that must be taken into account after purchasing a solid fuel boiler KCHM 5:

• It is necessary to carefully check each structural element for defects and other things; if even one part has a flaw, the unit will not serve for a long time.
• Installation must be carried out by highly qualified craftsmen.
• Proper installation of the chimney is no less important than the installation of the KCHM device itself.

The consequences of improper assembly or installation of a solid fuel boiler KCHM 5 will be:

• The device will begin to “smoke”;
• There will be a “knocking out” of smoke into the house;
• Poor quality room heating;
• Excessive overheating of the room;
• Fuel boiling;
• Failure of a cast iron unit;
• Problems occurring in the control system.

That is why extensive experience in installing boiler equipment and professionalism should be your main criterion when choosing an organization to help with the installation of equipment.

Solid fuel boilers KCHM 5 are used both for heating residential buildings, apartments, offices, and for heating industrial workshops, service stations, warehouses or production premises.

Circulation can be either forced or natural; the KChM 5 solid fuel boiler can cope with any task. In addition, these heat generators are equipped with thermostats, these devices help maintain the temperature automatically, and in combination with the ability to work at different types fuel, this allows us to talk about the versatility and indispensability of such a device in any enterprise or in a private home.

In addition to thermostats, such equipment can be equipped with thermometers or other sensors that allow you to constantly monitor the condition of the equipment.

Autonomous systems It would not hurt to install a solid fuel generator in the house, because it is not dependent on electricity. The main thing is to choose the right power for the unit, that is, the number of sections. If you approach this issue incorrectly, you can create two problems - when you sort out sections for a room, there will be an overconsumption of solid fuel, and if the sections are assembled too low, the room will not heat up.

Let's take a closer look at what parts the KChM-5 boiler consists of:

• We have already mentioned that the heat exchanger consists of sections. At the bottom of the near section there is a pipe for connecting the return line of the heating system, and at the top of the far section there is a pipe for connecting the direct line.
• There are three doors on the front panel: the loading door, the scooping door and the ash pan door. The loading chamber has holes for access of secondary air. By adjusting the amount of opening of the ash pan door, you can regulate the intensity of combustion. This process is performed either manually using an adjusting screw or using a draft regulator.
• On the rear wall of the boiler there is a chimney pipe with a smoke damper. Thanks to it, you can regulate the output of combustion products.
• The entire body of the KChM-5 is insulated with a special material to prevent heat loss and increase operating efficiency. The outside of the body is coated with wear-resistant paint.
• To prevent boiling and control the water temperature in the heating system, a thermometer is provided. It measures the water temperature in the middle section and displays the readings on the front panel.

Let's look at the main technical characteristics from the manufacturer's official website:

As you can see, KChM-5 stands out from the general mass of solid fuel boilers. Let's move on to analyzing its advantages and disadvantages.

Advantages and disadvantages

So, what advantages does the KChM-5 boiler have in comparison with its solid fuel counterparts? Let's look at them in order:

• Thanks to the use of cast iron, proven design and quality of workmanship, the KChM-5 will serve you for at least 25 years.
• One of the main advantages over others solid fuel boilers Its versatility should be noted. With the help of easily installed additional equipment, it can be converted to another type of fuel, such as gas, diesel, fuel pellets.
• The simplicity of the design of the KChM-5 boiler greatly simplifies its maintenance. The device is easy to clean and eliminate minor problems that inevitably arise during the operation of any unit.
• The use of a sectional heat exchanger made it possible to create an impressive range of different capacities from 20 to 80 kW.
• Design features, as well as the presence of thermal insulation, made it possible to achieve an efficiency of at least 78 percent when working with wood and coal.

Advice: The most preferred fuel for which the best efficiency is achieved is anthrocyte coal with a diameter of 40-60 mm. Firewood should be used with a humidity of at least 20%. With wetter fuel, the boiler efficiency will decrease significantly.

Installation and connection features

When installing KChM-5 with your own hands, you must comply with a number of mandatory requirements. Compliance with these rules will significantly extend the service life of the solid fuel boiler, and will also make its use convenient and safe. Let's take a closer look at the installation requirements:

1. The KChM-5 boiler must be installed so that the distance from the rear wall of the boiler to the wall of the boiler room is at least 250 mm. The distance between the side walls and the walls of the boiler room is at least 100 mm. To provide access to the rear, a passage of at least 400 mm wide must be provided on one side. A space of at least 1 m² must be provided near the front of the boiler for ease of loading and cleaning.
2. Installation is carried out on a floor made of non-combustible material or on a special plinth. There should be no flammable materials around at a distance of at least 400 mm. It is also prohibited to store fuel at a distance of at least 400 mm from the boiler. It is better to store it generally in a separate room.
3. The heating system must use clean, non-hard water without foreign impurities. High hardness water causes scale formation and significantly reduces the service life of a solid fuel heating boiler, as well as the entire heating system as a whole.
