Overview of KVR boilers with technical characteristics

Selecting the ideal heating system for your house is essential for cost-effectiveness, comfort, and efficiency. KVR boilers are distinguished from other options by their dependability and efficiency. We’ll give you a general introduction to KVR boilers in this post and then dive into their technical details to assist you in making an informed choice for your insulation and heating requirements.

It is crucial to first comprehend what a KVR boiler is and how it operates. KVR boilers, sometimes referred to as combi boilers or combination boilers, are small appliances that can provide hot water and central heating on demand. KVR boilers are efficient and take up less space than conventional boilers because they heat water straight from the mains whenever it’s needed, as opposed to conventional boilers that store hot water in a cylinder.

The heating capacity and efficiency of KVR boilers are important technical factors to take into account. To accommodate different home needs, KVR boilers are available in a range of sizes and output ratings. The amount of heat the boiler can produce in an hour is indicated by the output rating, which is expressed in kilowatts (kW). To effectively heat your house without wasting energy, you must select a KVR boiler with the appropriate output.

Efficiency is yet another important consideration when choosing a KVR boiler. Boilers with higher efficiency levels produce more useable heat from the fuel they consume, which lowers energy costs and lowers carbon emissions. KVR boilers are generally rated between 90% and 98% efficient; newer models use cutting-edge technologies to optimize efficiency.

Apart from the heating capacity and efficiency, it’s crucial to take into account the features and controls that KVR boilers provide. With the help of sophisticated heating controls, wireless connectivity, and programmable thermostats, modern KVR boilers enable homeowners to maximize energy efficiency and comfort. For added convenience and peace of mind, certain models also come equipped with frost protection and weather compensation features.

Ensuring optimal insulation of your home is crucial for optimizing energy efficiency and reducing heat loss when installing a KVR boiler. Sufficient insulation contributes to heat retention in your house, which lessens boiler workload and lowers heating expenses. You can save money and lessen your carbon footprint while creating a warm and cozy living space with a KVR boiler and efficient insulation.

Since they are all based on the standards of the former Soviet Union, KVr boilers are produced by numerous manufacturers in Russia and the CIS countries; they are nearly identical.

The most well-known producers of KVr boilers are the following: TD "Energomash," Barnaul Energy Chemical Plant, Biysky Boiler Plant, Boiler Plant of Siberia LLC, Novokuznetsk Boiler Plant, Khabarovsk Boiler Plant "Energoprom," and PJSC "Khimmash" (Ukraine).

Boilers in the KVr and KVm series share a common marking and are not under the supervision of Russia’s Gosgortechnadzor.

  • KV – water-heating, for heating of water coolant;
  • P/M/TS/TSV – fuel type and furnace chamber parameters;
  • P – manual fuel loading,
  • M – mechanical fuel loading, for example, KVM 1;
  • TS – layer furnace chamber;
  • TSV – layer furnace chamber with air heating.

Boiler device

The developed convective heating surface and furnace chamber of KVr boilers allow the coolant to circulate while absorbing heat from the flue gases.

The boiler’s design determines the efficiency of heat transfer from flue gases to water and guarantees high efficiency. Large dimensions are used in the furnace chamber to ensure that the combustion process is organized properly. A convective bundle of boiler tubes closes the chamber’s vault and side walls.

By adding specific plugs and baffles to the collectors, one can achieve multi-pass coolant circulation through screens and panels while controlling the internal circuit’s circulation speed. The units function in conjunction with specific pumping machinery to keep the coolant flowing at the proper speed, preventing convective pipe scaling and overheating. to avoid the possibility of a pipe burst and the unit’s emergency stop.

Appropriately setting up the boiler’s draught-blowing mode is crucial for the thorough burning of fuel. Gas exhaust is done through the chimney. The system of smoke channels is installed for this reason; it offers the lowest indications of coal underburning, both mechanically and chemically, increasing efficiency and lowering harmful emissions into the atmosphere.

  1. The fuel is fed manually through the furnace door to the ash pan grate.
  2. In the process of coal combustion, volatile substances are formed, which burn, releasing heat energy and non-combustible residue in the form of slag.
  3. Uniformity and completeness of combustion is ensured by forced air supply with the help of blowing fan through the ventilation box.
  4. Combustion products, wash the festoon and pass to the convective part, where they are cooled by the coolant, circulating through the pipes.
  5. Cooled boiler gases enter the gas duct, the process of movement is regulated by a gate valve.
  6. Inspection and cleaning of the convection bundle is performed by means of hatches.
  7. The rear cladding on the body is made removable to increase maintainability.
  8. Blower fan is connected to the gas duct.
