Optimization and Application of TCA Cooling System for M701F4 Gas Turbine
This paper compares the advantages and disadvantages of air-cooled cooler,high-pressure feed-water pump combined water-cooled cooler,and independent TCA pump water-cooled cooler.An analysis was conducted on the cold end of the TCA cooling system of the Mitsubishi M 701 F4 gas turbine combined cycle unit from an energy-saving perspective.Based on the actual application of an independent TCA pump in a certain power plant,analysis and summary were conducted from the aspects of operation mode and e-conomy.The paper is thus of certain guiding significance for the design,installation,debugging and opera-tion of similar units in the future.
