GAS TURBINE DEVICE HAVING VAPORIZER FOR LPG-MIXED WATER

摘要

PURPOSE:To provide a gas turbine provided with an LPG mixture vaporizer which is designed to eliminate a need for another vaporizer to vaporize liquid LPG and an external heat source therefor and simultaneously generate steam having a pressure high enough to allow charge of it in the combustor of the gas turbine. CONSTITUTION:A gas turbine device having a vaporizer for LPG mixture water comprises a gas turbine (consisting of a compressor 20, a turbine 21, and a combustor 22) to use LPG gas as fuel; a boiler 25 to use exhaust gas from the gas turbine as a heat source; a mixer 34 to generate LPG-mixed water of liquid LPG 6 and water 9: a vaporizer 36 to vaporize the LPG-mixed water by using exhaust gas from the gas turbine as a heat source ; a steam separator 32 to separate mixture gas 11 of vaporized LPG gas and steam and hot water 10 from each other; a gas line through which separated mixture gas is fed to the combustor 22 of the gas turbine; and a hot water line through which hot water is fed to a waste heat boiler.
