The difference between single and double-circuit boilers
Combi boilers, which are called pyrolysis, characterized by the presence of an additional single-circuit furnace, whereby combusted gases are not emitted directly into the pipe and saturated with air and stays in the second chamber. This factor and the reason for this high efficiency. The solid casing of the heating equipment with a water circuit may be made of steel or cast iron.
Turbofan wall mounted boiler
Single-loop boiler provides only heating water for radiators. Its design is as follows:
- firebox - a chamber in which the combustion of the fuel;
- ashpan - box for waste resulting from combustion;
- chimney - system exhaust of burnt gases;
- shirt - water heat exchanger, placed directly in the furnace.
The operating principle of the solid fuel boiler
The principle of operation of the equipment is as follows: the furnace being laid firewood or coal. Burning, they produce heat. Due shirt heat accumulates and is transmitted to the heat carrier (water), which carries it throughout the system.

"Water jacket", which are equipped with some boilers is more efficient in terms of heat transfer. This complicated form of boiler water, in which all the double wall. In the space formed by the (3-5 cm) circulates coolant, which enables it to quickly warm up.
EXAMPLE work pyrolysis boiler water circuit
Water circuit made of steel tubes with a diameter of 5-6 cm, is considered to be no less effective than the previous embodiment. The curved profile of the tubular coil extends above and along the walls of the furnace, inside the water circulates slowly and provides heat to the room. The advantage of such models is that they are much easier to repair.

The circulation pump will maintain a solid fuel boiler in the winter from freezing. That is, if a working system pumpless leave for several days unattended fuel burn completely, no more water to circulate and freeze. In this situation, the pipe just burst with. But in the presence of the circulation pump such trouble does not happen. Slowly moving through the pipes in the winter does not freeze even cold water.
One of the important details of the heater - heating system is the pump
Rates long solid combustion boiler with a hot water loop is higher than in conventional furnaces. But this cost is justified. Water from the boiler can be used in a wide variety of needs.

Features pyrolysis boilers
As already mentioned above, pyrolysis boilers have two combustion chambers. The first fuel burns immediately and the other - the gases developed by this fuel. If the furnace put raw wood, which is quite possible, they begin to give off steam in the winter.
Several types of pyrolysis long burning boilers
The second chamber eliminates the negative effect on the combustion process. It enters the hot gas and moisture cures. On its way it saturates the gas with air, which contributes to further combustion. To separate chambers grate is used on which are cleaved. To operate the pyrolysis system needs forced blowing, it provides an induced draft fan.

How does pyrolysis system:
- Fuel is placed on the grate.
- Kindle boiler.
- Close the flap of the furnace.
- Start the induced draft fan.
- Combustion chamber creates a high temperature, resulting in formation of volatile products of combustion in the form of nitrogen and hydrogen.
- These formations enter the second chamber and mix with the air stream.
- Complete combustion, and the extracted heat back into the first chamber.
