Gas turbine system of high thermal efficiency by use of methanolic fuel

Abstract: PURPOSE:To obtain a high thermal efficiency by a simple and inexpensive system by providing a methanol carburator, a boiler, an endthermic reactor, a superheater, and a heater in a specified order so as to mix superheated steam with combustion gas for feeding the mixture to a turbine. CONSTITUTION:High temperature exhaust gas exhausted from a turbine 1 is discharged into the atmosphere through gas flues 4 and 4', however, waste heat of the exhaust gas is recovered by each of equipments on the halfway. In this case, No.1 waste heat recovery system which is composed of a steam superheater 5, and an endthermic reaction produced gas heater 6, and No.3 waste heat recovery system which is composed of a boiler 8 and a methanol carburator 9, are arranged in series in order along the flow line of turbine exhaust gas. And after steam which is extracted from the boiler 8 through lines 25 and 32, is superheated by the superheater 5, it is extracted as superheated steam by a line 33. And then the superheated steam is mixed with combustion gas of endthermic reaction produced gas so as to be fed into the turbine 1.
