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

Wood Syngas
Uplinjanje biomase
Syngas CO, H2, CH4, CO2, N2
Air (Oxygen)
Biomass
Ash, Carbon
Cogeneration – heat and power
Thermal application process heat
200-650 oC

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
