Abstract
We are involved in a development of small-scale gasification and power generation system in order to constract a small scale dispersed power system suitable for the biomass circumstance in Japan. Our system has characteristics on gasification part and power generation part. Developed gasification process consists of two parts: pyrolysis part (rotary kiln) and char gasification part (downdraft gasifier) in order to handle various biomass with wide ranges in material size and shape 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 produced gas calorie is low and variable. We performed pilot tests with gasification and power generation system. This report provides a progress of gasification and power generation tests and issues to be solved for commercialization.
