Pyrolysis boilers

Pyrolysis boiler

— a solid fuel boiler (see the relevant paragraph) uses the phenomenon of pyrolysis during operation. Pyrolysis is called the release of combustible gas from the fuel when heated to high temperatures. This gas in pyrolysis boilers is also burned in the firebox. Due to this the efficiency is significantly increased. Another advantage of such boilers is less waste. On the other hand, such models are not cheap; they require electricity to operate, and the fuel must be as dry as possible.
