The principle of operation of TCD

Long-term combustion in the tcdg furnace can be provided in 2 ways::

  • The principle of top combustion. In the combustion chamber, fuel does not burn, but smolders with limited oxygen access. The cylindrical firebox is located in the upper part of the unit and has a cylindrical shape. The gas released during smouldering enters the afterburner chamber, where oxygen is supplied to the air for its complete combustion. As a result, almost complete combustion of fuel occurs with the active release of thermal energy.
  • Pyrolysis principle. The furnace chamber is located in the lower part. There is also an active smouldering of fuel with limited oxygen access. The combustible gas rises up and reaches the second chamber, where, being enriched with oxygen, it is completely burned.

Advantages and disadvantages

Advantages of the considered boilers:

  • high efficiency exceeding 90%%;
  • affordable and fairly cheap fuel;
  • easy to install, manage and operate;
  • almost complete combustion of combustion products;
  • increased durability;
  • affordable price.

It should also be noted that there are some disadvantages of the tcdg:

  • need for a separate room for installation;
  • the need for periodic cleaning of the ash;
  • arrangement of a storage room for fuel reserves.

In budget designs, fuel is loaded manually, which can also be attributed to the disadvantages of such equipment.

TOP-10 best long-burning solid fuel boilers: rating of 2021 models with a water circuit and wood for home heating

Water outline

To provide Autonomous hot water supply, in addition to the heating system, tcdgs with a water circuit or double-circuit boilers are installed. These units have 2 independent circuits for water circulation. An additional heat exchanger acts as a boiler and is intended only for heating water.

If the water pump is connected to the water supply network, then water circulation through both circuits is provided without forced supply, i.e. due to pressure in the water supply system. When there is no centralized coolant supply, a storage tank is required. It contains the necessary supply of water to meet the need.

The tank is usually installed above the boiler. In a number of models of units, a built-in expansion tank is provided. Forced water supply is provided by a circulation pump.

How is the boiler power selected?

The exact calculation of the required boiler capacity for heating a house is quite complex. A simple method is usually used: 1 kW of thermal energy is needed to heat an area of 10 m2.

For unforeseen cases, a reserve of 10-15% capacity is created. When using a water circuit or installing an additional boiler, additional energy is required in the order of 25-30%.

Climatic conditions make their own adjustments. In cold regions, where the air temperature can drop below minus 30 degrees, tcdg is selected at the rate of 1.6-2 kW per 10 m2 of room area. For the southern regions of the country, the requirement can be reduced: 0.8-0.9 kW per 10 m2 .
