Pyrolytic gasification

Pyrolytic gasification is a thermochemical process through which a combustible gas mixture is extract from biomass.

The gas mixture (syngas) contains hydrogen, carbon monoxide and methane, has low carbon content and the process produce a solid waste (biochar) containing all the remaining carbon.

Internally developed Downdraft Open Core micro-gasifier.

• Low CO2 emission
• Biochar production - Excellent terrain improver, can be easily and advantageously disposed on the ground.
• Input biomass from agricultural, zootechnical or industrial waste - Typically wood micro-chips or pellet, can be obtained without resort to virgin wood, because the pyrolytic reactor is insensitive to ashes or other substances normally not tolerated from pellet stove.


Burner, as well as the whole system, works by sucked air from exhaust fan.

Depression generated in the combustion chamber let syngas and combustion air to flow in it.

Lean combustion controlled by Lambda sensor

  • Condensing exhaust gas
  • Combustion in porous media
  • Stirling heat exchange optimized combustion chamber design


Very low CO and pollutant emissions

  • Extremely low particular matter emission
  • Good heat input in Stirling engine
  • Good heat recovery
Stirling Engine

External combustion Stirling engine is particularly suitable for micro-CHP application because is absolutely insensitive to the kind of combustible to be used, and compared with traditional internal combustion engines, has lower noise emission, lower vibrations and higher efficiency in very low output power range.

External combustion let also to optimize fuel oxidation and obtain low pollutant and particulate matter emission.

1.0 kW free piston Stirling engine.

AC electrical power output suitable for both grid connection and island/hybrid installations.

  • Low noise
  • High efficiency
  • Simple construction
  • Easy maintenance
