Title:
GAS TURBINE GENERATING DEVICE
Document Type and Number:
Japanese Patent JP3778225
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas turbine generating device to perform intermediate cooling of a large quantity of heat without increasing an amount of cooling water to a value higher than an amount of supply water and achieve thermal efficiency higher than a conventional thermal efficiency.
SOLUTION: An intermediate cooler 14 consisting of a gas liquid heat- exchanger 12 and a steam generator 13 is arranged in the middle of a plurality of compressors 1a and 1b. Compressed air by a compressor 1a on the low pressure side is cooled by, in the order, of the steam generator 13 and the gas liquid heat-exchanger 12. Cooling water is preheated by the gas liquid heat- exchanger 12, at least a part thereof is then vaporized by a steam generator 13, and generating steam is fed to a turbine 5b. Further, a part of cooling water heated by the gas liquid heat-exchanger 12 is fed as boiler feedwater to a deaerating feedwater heater 15, a part of steam generated by the steam generator 13 is fed to the deaerating feedwater heater 15, and this constitution heats boilers feedwater to a saturation temperature for deaeration. A turbine to feed steam is a gas turbine or a steam turbine.
