Abstract
Utilization of biomass and effective use of its energy are important issues from the viewpoint of preventing global warming (reducing greenhouse gases) and resource recycling. Generation by biomass-based waste is expected to become a stable power source that is not affected by weather and other such factors. In order to disseminate compact, dispersed power generation using biomass with regional characteristics, high efficiency power generation technology is required for small- and medium-sized facilities. Power generation using a gas engine is not influenced by facility size. Fluidized bed gasification is a technology expected to produce gaseous fuel for gas engines and is considered important in the accumulation of information to influence material and gasification conditions on synthesized gas compositions. Unfortunately, till now, realization of MSW disposal facilities generating electricity using gasification and gas engines is still limited. A woody biomass power generation facility that uses gasification combustion has, however, been running stably since April 2016. Operating at a low total air ratio under 1.2, boiler efficiency has exceeded 90 % and a power generation efficiency rate of 29 % has been made achieved.
