First Experiences with the New Chalmers Gasifier

摘要: During summer 2007 a 2–6 MWth indirect gasification section was integrated into the loop of existing 82➀2 circulating fluidized bed boiler at Chalmers University. With help particle distributor unit is connected to after cyclone. Hot material entrained from so transferred gasifier providing heat for production nearly nitrogen free product gas. Non-gasified char returned together with and converted. Biomass can be fed both sections; gasifier. The separated via two seals distributer, directing particles either back or section. For that reason CFB operated even retrofit independently, just like before, in combined combustion/gasification mode. This possibility keeps risk low. As, furthermore, investment costs integration are considerably lower than standalone units size, an easy way extend potential Boiler towards bi- tri-generation (heat, power, fuel) enter new markets.
