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 gasification Downdraft gasifier

Wood Syngas Biomass Air (Oxygen) Uplinjanje biomase Syngas CO, H 2, CH 4, CO 2, N 2 Thermal application process heat 200-650 o C Cogeneration heat and power Ash, Carbon

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

Volter CHP frame for container

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

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

Power regulation and control Main logic processor Schneider M258 logic touch screen control panel Inverter (ABB ACS800)
