Abstract
This report introduces five biomass gasification power generation plants in Europe, three nations, Swit-zerland, Austria and Germany, where the author visited November 2004. PYROFORCE in Switzerland used fixed bed gasification system with 200kW GE-Jenbacher gas engine. This gasification system promotes very little tar even as a fixed bed gasifier because of optimization of shape of reactor and airflow. Gassing in Austria uses internally circulating fluidized-bed gasification system. Characteristic of this system are to promote medium calorific gas because of using steam and to use combustion heat efficiently for gasification. This plant is equipped with 2000kW GE-Jenbacher gas engine. Electricity is sold for homes and factories, heat is supplied to regional heating system in the city. Future Energy GmbH and CHOREN GmbH in Ger-many operate the entrained bed gasification system. In Future Energy, there are three type entrained bed gasification systems for fuel types. CHOREN has established Carbo-V system with entrained bed with the charcoal fire pit. All of plants use woody biomass. Thus, the author thinks it difficult to transfer European techniques to Japan without modifications because of different surroundings. It is also needed to develop not alone technology, but policy to adopt biomass generation in Japan.
