Abstract
Power generation with a gas turbine using a gasified fuel of inferior quality is accomplished with high efficiency by a method which comprises bleeding part of highly compressed air emanating from an air compressor driven by a gas turbine and introducing the part of highly compressed air into an oxygen adsorbing tower containing an oxygen adsorbent thereby causing the oxygen from the highly compressed air to be adsorbed by the oxygen adsorbent and, at the same time, allowing the nitrogen gas from the highly compressed air to flow in a highly compressed state through the oxygen adsorbing tower, desorbing the adsorbed oxygen from the oxygen adsorbent under a vacuum, compressing the oxygen gas resulting from the desorption and gasifying a fuel of inferior quality with the compressed oxygen gas as an oxidizing agent, effecting combustion of the gasified fuel of inferior quality with the remainder of the compressed air produced by air compressor, mixing the gas arising from the combustion with the highly compressed nitrogen gas having flowed through the adsorbing tower, and introducing the resultant mixture into the gas turbine thereby driving the gas turbine and inducing power generation.
