B106 Gasification Performance of Solid Fuels Using High Temperature Air Blown Pebble Bed Gasifier

Abstract

A new distributed gasification system for solid fuels is proposed, which is named as MEET (the Multi-staged Enthalpy Extraction Tlechno]ogy) 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 faci]ity 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 tlow bed, High temperature air ef about 1,OOO℃ is used as a gas"ication 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 technicai feasibility of the MEET-II faci[ity.
