Abstract
CRIEPI has been conducting R & D activities on development of "High-efficiency Biomass/Waste Carbonizing Gasification Power Generation System". This system can use various fuels by integrating the carbonizing technology as a pretreatment equipment with the entrained-flow gasification technology. This system can obtain high thermal efficiency because the fuel such as biomass and waste is fed into the gasifier after pyrolyzed in the carbonizer by using the exhaust gas from the power generation system such as the gas engine. As a result of gasification tests of wood biomass, it was clear to be able to achieve a high efficiency by the carbonizing gasifier.
