We are involved in a development of small-scale gasification and power generation system in which biomass can be converted into energy with high efficiency. Our system has characteristics on gasification part and power generation part. Our gasification process consists of two parts: pyrolysis part (rotary kiln) and char gasification part (downdraft gasifier) in order to handle a relatively wide range of feed material shapes and to produce gas with little amount of tar. Meanwhile, in our power generation part, we tried to apply a mass-manufactured automobile engine with our own control system and to secure high generation efficiency even though the calorie of the produced gas generated by biomass gasification is low and variable. We performed fundamental experiments of the above-mentioned two parts and pilot tests with gasification and power generation system (50 kW electricity output). This report provides a summary of fundamental experiments and progress of gasification and power generation tests.
