Abstract

PURPOSE:To decrease consumption of a power and to facilitate installation, by a method wherein an oxygen enriched air, sucked by a turbo blower driven by a gas turbine, is guide to a heat exchanger through an oxygen enriching film, and is heated through heat exchange with high temperature exhaust gas from the gas turbine. CONSTITUTION:An air from a gas turbine 1 is guided to a combustion chamber 5 through a line 4 by means of a compressor 3 after flowing through a line 2. Exhaust gas from a combustion chamber 5 drives a turbine 8 at a high speed. The turbine drives a compressor 3. Exhaust gas from the turbine 8 is guided to a heat exhanger 10 through a pipeline 9 and further to a heat exchanger 12 through a pipeline 11. With the aid of the turbine 8, the vane of a turbo blower 13 is driven at a high speed to suck the air through a pipeline 15 from the heat exchanger 12 and an oxygen enriching film 14. The passage of the air through the heat exchanger 12 results in an increase in the temperature of the air fed to the oxygen enriching film 14. Consecutively, an oxygen enriched air is further heated in the heat exchanger 10, and is fed to a burner 18 through a pipeline 17.
