SLIGHTLY PRESSURIZED FUEL GAS TURBINE

摘要

PURPOSE:To eliminate the need of especially disposing a gas compressor so as to reduce the expenditure for installing an apparatus by owing compression of slightly pressurized fuel gas to the shaft power of a gas turbine and using its revolution and drive power. CONSTITUTION:A gas supply chamber 7 having an air intake port is disposed at the air supply side of a compressor 2 and a slightly pressurized fuel gas pipe 12 is connected thereto via a flow control valve 11. Air is thereby carried from the intake port 6 to the gas supply chamber 7 by the compressor 2 which is driven by a gas turbine 1 and is compressed along with the slightly pressurized fuel gas which is fed from nozzles formed in ejecttion pipes 9 and 10 in the form of mixture gas, which is squeezed to be sent into a combustion chamber 3 and ignited to be burnt therein. The need of independently installing a special gas compressor is therefore eliminated so that the expenditure for installing an apparatus may be reduced extremely.
