Product Description

Wood gasifying boiler BURNiT PyroBurn Alpha PLUS

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

Available sizes, kW: 20, 32, 40

Wood gasification

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.

Product Features


•  The built-in proportional-integral derivative controller monitors the burning process and controls the fan speed to achieve optimal yield and economy of fuel;
•  Fume extraction fan;
klapa
•  Fume extraction device on the upper combustion chamber keeps smoke from polluting the boiler room during reloading; 
•  Large firebox door ensures easy loading even with bigger logs (length of logs up to 50 cm);
•  Combustion chamber protected on all sides by ceramic plates;
•  Eyepiece for viewing the combustion process;


Safety devices

For a safe and reliable operation of the boiler, a number of safety devices are installed
 
- Upon reaching 95°С the controller turns the fan off and activates the pumps for domestic hot water and heating system. An independent STB thermostat shuts down the fan upon reaching 99°С
- Safety heat evacuator
- Pressure relief valve 3 bar
- Safety heat evacuator: a tap-water filled line passes through the uppermost part of the boiler body. In case of overheating it is triggered open by a thermostatic valve (not included) to evacuate the heat off the boiler.

Fuel

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 500mm. 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.
