Kholmov boiler design

The device’s operating principle dictates how the heating system is assembled. The vertical placement of the heat exchanger chamber and furnace compartment in the Kholmova shaft boiler permits natural convection of flue gases to the upper afterburning compartment. The firebox is positioned at the shaft’s maximum height. To load firewood, open the product’s upper hatch.

The components of the Kholmova long-burning boiler are as follows:

  • the body is metal;
  • fuel shaft;
  • spigots for connection to the chimney and heat supply system;
  • doors for solid fuel loading and chamber cleaning;
  • shaft, in which the heat exchanger chamber and convection chamber, grates are located;
  • safety devices – expansion compensators, safety valve, thermoregulator.

Additional parts can be added to Holmov boiler drawings, for instance, if the equipment is to be assembled manually or if operating safety is to be increased.

Differences by capacity

In serial production, the Kholmov boiler is modified in three main ways.

Capacity Features
10 kW model Used for heating small spaces such as a garage, a separate outbuilding or a workshop
12 kW model Provides additional power increase. Due to minor modifications, the weight of the Kholmova boiler reaches 255 kg. At the same time, the dimensions of the device allow to carry it through the doorway
25 kW model The most productive in the line of TKZ (Taganrog Boiler Works). Its power is enough to heat a group of rooms, the whole country house

Energy-dependent and non-volatile

The units’ modifications are chosen based on the operating environment. Boilers made by Kholmova that are energy-independent come with a smoke extractor. A unique controller and thermoregulator govern their operations. Additional safety-enhancing devices are incorporated into the design.

Energy-independent boilers made by Kholmova employ a more straightforward layout while maintaining the assembly concept, which prevents emergency scenarios. Do not need to be connected to the supply chain.

Safety in the design

A significant heating of the body part is a crucial stage in the operation of solid fuel boilers. The Kholmov boiler is designed with expansion joints to prevent both shell expansion and weld seam divergence. Because of this configuration, the installation’s shape is maintained for the duration that the mine system is in use.

The lower body, where the heating temperature is lower, is another area where the design’s safety is guaranteed. Installing a special screen is not necessary to place the boiler Kholmova on the surface; instead, the unit can be placed on the legs.

The principle of operation of the Kholmov boiler

The unit’s device enables the most efficient use of fuel energy. The Kholmov boiler works on two principles: first, heat is produced through the combustion of raw materials, and second, the coolant is further heated through the afterburning of released gases. This method extends the operation time on a single load, reduces waste, and optimizes the effect of heat generation.

Combustion process

The bottom layer of fuel must first be burned for the Kholmov long burning boiler to function. With a high concentration of smoke and other combustion products, the upper loading tier begins to smolder. The firewood produces the most heat at the end of the cycle. Gases keep building up in the afterburning chamber at the same time.

The term "controlled combustion" refers to the installation’s ability to regulate the amount of incoming air. The Kholmov boiler carries out this process in three ways:

  1. Adjustment of the damper position placed on the blower door.
  2. Organization of forced air supply to the lower and upper chambers
  3. Reduction of gas pressure in the afterburning chamber by mounting a smoke evacuator.

One method of managing the heating medium’s parameters is through mechanical draught regulation. For example, by closing the door, you can cut back on the air supply once the room or shaft temperature reaches its typical level. The regulator (sensor), installed at the coolant passage location and covered by a protective sleeve, takes over the control function.

The size of the sensing element grows or shrinks in response to variations in the heating intensity. Instant communication with the air damper is made possible by a rigid connection to the stem.

Upper and lower chamber

A partition wall made of steel divides the compartments apart. The convection chamber’s accumulated combustion products are heated through a gap in the plate. Efficiency (or coefficient of performance) is significantly increased by complete combustion.

The lower chamber produces the majority of the heat output. Almost all of the remaining energy is lost during the convection chamber process.

Gas accumulation in the upper compartment is done to keep the fuel smoldering process going. In circumstances where there is a shortage of oxygen, there is a stronger heat transfer concurrently with increasing pressure. The combustion process known as pyrolysis heats the compartment to temperatures between 800 and 100 degrees Celsius while actively replenishing the coolant circuit.

Which are the most affordable solid fuel boilers, and can you build the appliance yourself? Regarding everything on the link.

Looking to heat your home efficiently? Consider the Kholmova solid fuel boiler. It offers several advantages, such as cost-effectiveness and reliability. By burning solid fuels like wood or coal, it provides consistent warmth throughout your house, even during power outages. Plus, solid fuel is often cheaper than other heating options, saving you money in the long run. However, there are some downsides to consider. Solid fuel boilers require regular maintenance, including cleaning out ash and refueling. They also emit more pollutants compared to cleaner energy sources like natural gas. Despite these drawbacks, the Kholmova solid fuel boiler remains a popular choice for those seeking an affordable and dependable heating solution.

Choosing a solid fuel boiler, such as the Kholmova model, has pros and cons of its own when it comes to heating your house. Its efficiency and dependability in delivering steady heat is one of its main advantages, particularly in locations where alternative fuel sources might not be easily accessible. This can be especially helpful for homes that are off the grid or in rural areas.

Additionally, because they use locally sourced fuels like coal or wood, solid fuel boilers like the Kholmova model provide a degree of independence from fluctuating energy prices. Over time, this may save costs, particularly if these fuels are widely available and reasonably priced where you live.

But it’s crucial to balance these advantages with the disadvantages. Regular cleaning and maintenance are necessary for solid fuel boilers to guarantee maximum efficiency and security. Ash and soot buildup can decrease effectiveness and raise the possibility of chimney fires, so careful maintenance is required.

Moreover, one must take into account how burning solid fuels will affect the environment. Carbon dioxide and other pollutants are still released into the atmosphere during the combustion of wood and other biomass sources, despite their renewable nature. A portion of this effect can be lessened by employing fuel that is sourced sustainably and managing emissions through effective burning techniques.

In summary, the choice to purchase a Kholmova solid fuel boiler ought to be supported by a thorough assessment of your heating requirements, availability of fuel sources, readiness for routine maintenance, and thought for the environment. Although it has benefits like dependability and possible cost savings, it also needs constant maintenance and, if improperly handled, could worsen air pollution. In the end, balancing these advantages and disadvantages will enable you to decide whether a solid fuel boiler is in line with your heating needs and principles.
