Wood gasifying boiler BURNiT PyroBurn LAMBDA

A highly-efficient wood gasifying boiler, designed for economical and ecological heating of medium to large-sized premises.

The boiler  PyroBurn LAMBDA provides:
- intuitive operation interface
cleaning system (manual)
- heat output regulation
- sophisticated safety systems
- Thanks to the integrated lambda sensor the combustion process is optimized to such an extent that boiler efficiency exceeds 91%, and exhaust gas emissions conform to strictest EU standards. 
- 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 ensure its safe operation.

Tested and approved according to EN 303-5, class 5

Available sizes kW: 22 up to 27, 27 up to 32

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 150°С. Thanks to the wood gasification principle the fuel is most efficiently consumed with minimum carbon emissions and ash.

Product Features

  • The microprocessor control is able to control operation of buffer tank and one DHW circuit through the built-in terminals for connecting circulation pumps and DHW sensor.
  • Lambda sensor for accurate combustion process management.
  • Cleaning system (manual).
  • Fume exhaust fan.
  • Exhaust gas sensor.
  • Open door sensor and fume extraction opening chamber keeps smoke from polluting the boiler room during reloading. Open door sensor detects when boiler door is open and activates fume extractor fan on full speed (100%). Fume extractor fan draws smoke from the chamber to the chimney via back-side upper chamber opening.
  • Actuator-driven air flaps for air intake management.
  • 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

- 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.
