Gasification solid fuel boiler Burnit PyroBurn Alpha Plus 20 for central heating of premises. Constructed for solid fuel burning - wood and briquettes.
A highly-efficient wood gasifying boiler, designed for economical and ecological heating of medium to large-sized premises.
The PyroBurn Alpha PLUS boiler provides intuitive operation interface, cleaning system and heat output regulation as well as sophisticated safety systems.
Owing to the wood gasification technology employed the PyroBurn Alpha PLUS boiler reaches efficiency of above 90% and saves fuel. The water mantle embraces the combustion chamber in full to utilize the emitted heat most efficiently.
Built-in high temperature ceramic plates ensure uniform heat distribution and protection of the water mantle from the extreme heat produced by wood gasification (up to 1200°C). A complex of safety devices ensures its safe operation.
Tested and approved according to EN 303-5, class 3
The wood in the primary burning chamber is fired in a low-oxygen environment reaching about 580°С. It starts degrading to a combustible gas of carbon compounds which is directed to the orifice of the secondary combustion chamber. There, the gas is enriched with secondary air and ignites to reach temperature of up to 1200°C.
Before leaving the boiler body, the gas passes through a flue with built-in spiral turbulators where it gives away its heat to the water mantle and cools down to 180°С. Thanks to the wood gasification principle the fuel is most efficiently consumed with minimum carbon emissions and ash.
The central heating boiler can operate with natural untreated wood, but also with coal and compressed solid fuel such as briquettes. Maximum length of the wood logs is 330mm. Fuel moisture should be 15% or lower.
In order to use the maximum caloricity of the fuel, the wood logs should be dried for a prolonged period of time. High moisture levels reduces caloricity and the output power of the boiler.
