A new distributed gasification system for solid fuels is proposed, which is named as MEET (the Multi-staged Enthalpy Extraction Technology) system. In order to realize this system, a demonstration plant of commercial scale, the MEET-II, was constructed. The capacity of the MEET-II is 200kg/h. MEET-II facility consists of a pebble bed slagging-gasifier, a gas clean-up system, a high temperature air generator and a gas engine. The pebble bed slagging-gasifier contains a fixed ceramic ball bed under an entrained flow bed. High temperature air of about 1,000℃ is used as a gasification medium in order to obtain higher calorific value syngas. Gasification and power generation tests at the MEET-II facility were conducted using powdered wood biomass as fuels. These tests demonstrated technical feasibility of the MEET-II facility.
