ATMOSPHERIC PRESSURE GASIFICATION GENERATING DEVICE AND EMISSION CIRCULATION TYPE ATMOSPHERIC PRESSURE GENERATING DEVICE

摘要

PROBLEM TO BE SOLVED: To develop a technique suitable for recovering energy from atmospheric pressure and high temperature gas.;SOLUTION: In a turbine generating device, a combustor 12 is arranged at a front stage of a turbine 16 of a turbo machine, wherein the turbine 16 and compressors 20, 24 are connected with a shaft. Working fluid sequentially passes through the combustor 12, the turbine 16, and the compressors 20, 24 so as to generate axial output for generating power. This device comprises a gasification furnace 10 for gasification combusting various fuels, biomass and/or wastes; a regeneration heat exchanger 14 for heat-exchanging and cooling high temperature working gas from the turbine 16 with outside air, and preheating the outside air; and coolers 22, 26 for heat-exchanging the working gas with cooling medium at the inlet and intermediate of the compressors 20, 24 and cooling the gas. Combustible gas generated in the gasification furnace 10 is introduced to the combustor 12 as fuel, and the preheated air from the regeneration heat exchanger 14 is introduced to the combustor 12 and the gasification furnace 10.;COPYRIGHT: (C)2003,JPO
