What is biomass gasification?
Thermal decomposition of biomass:
Thermal process of
biomass
Oxygen proportion
(reaction)
Drying 0,0-0,0
Pyrolysis 0,0-0,1
Gasification 0,1-0,4
Combustion 1,0-1,3

Biomass heat and power (CHP)
Volter 40 kWe / 100 kWth
Dry wood chips
Heat ( hot water) 100 kWth
Electric power 40 kWe
Volter unit CHP

Wood chips transport and gasifier
• Fuel is fed from the silo by
screw and chain
conveyors
• Rotating feeder prevents
from free airflow to the
reactor. It also protects
from back fire

Syngas cooling and cleaning
1. Cooling before the filtering phase (heat recovering 1)
2. Dry filtering system (dust filter)
3. Control washing of Syngas (no running water needed)
4. Cooling to the final product gas temperature (heat recovering 2)
5. Cooled and filtered gas to motor

Heat and power from syngas
• Gas is fed to engine
• Heat is recovered from engine
and exhaust gas
• Engine turns the generator which
produces clean electricity
•“Agco Sisu Power” adapted diesel
engine with electric generator
