WASTE HEAT RECOVERY SYSTEM, GAS TURBINE PLANT PROVIDED WITH SAME, WASTE HEAT RECOVERY METHOD, AND INSTALLATION METHOD FOR WASTE HEAT RECOVERY SYSTEM

摘要

The present invention is provided with: a compressor (11) that compresses air (A); a combustor (21) that combusts a fuel (F) in the compressed air (A) and generates a combusted gas (G); a plurality of cooled air coolers (54) that extract air (A) from a plurality of tubular sites on the compressor (11), which is on a gas turbine (10) that has a turbine (31) that is driven by the combusted gas (G), the plurality of tubular sites having different pressures, and that cool the air (A) extracted at each location and generate cooled air (CA); and a waste heat recovery device (51) that recovers waste heat from at least two of the cooled air coolers (54) from among the plurality of cooled air coolers (54).
