POWER GENERATING METHOD OF GAS TURBINE USING GASIFIED GAS OF RESIDUAL FUEL AS FUEL

摘要

PURPOSE:To perform gas turbine power generation with residual fuel by adsorbing the oxygen of part of the compressed air under the high pressure of oxygen adsorbing towers, desorbing it under decompression as an oxidizer for gasifying crude fuel, mixing high-pressure nitrogen gas with the combustion gas burnt with the gasified gas and the remaining compressed air, and driving a gas turbine. CONSTITUTION:Part of the high-pressure compressed air from an air compressor 1 driven by a gas turbine 23 is extracted and introduced into oxygen adsorbing towers 5a, 5b storing oxygen adsorbents 10a, 10b to adsorb oxygen, it is fed under high pressure, and the oxygen adsorbed under decompression is desorbed from the oxygen adsorbents 10a, 10b. The desorbed oxygen gas is pressurized to gasify crude fuel as an oxidizer, the gasified gas is burnt with the remainder of the compressed air from the air compressor 1, the high-pressure nitrogen gas passing through adsorbing towers 5a, 5b is mixed with the combustion gas generated by combustion, the mixture is introduced into a gas turbine 23, and the turbine 23 is driven for power generation.
