Woody biomass such as the thinned wood is widely distributed in the mountain-ringed region and the field, and it is difficult economically to collect and to transport it. Therefore, small-scale power generation is suitable in many cases to utilize woody biomass. Development of small-scale power system based on the biomass gasification is under going. But because of so complicated system and high cost, the commercialization is not progressing as expected. Small-scale system which has high thermal efficiency and low cost is requested. So, we are developing small-scale power system, in which stirling engine power system is combined with biomass combustion furnace. We aim at high thermal efficiency and low cost of the biomass power system through this development. In this paper, based on basic performance, durability, economical efficiency, etc. which were acquired through the verification test of the demonstration plant, it makes a comprehensive evaluation of the biomass power plant with 30kW-class stirling engine.
