FIELD: thermal engineering; thermal power plants; blowers, pumps, and compressors. SUBSTANCE: part of saturated steam is additionally extracted from waste-heat recovery boiler to off-line boiler, additionally evaporated, and reheated in the latter and in waste-heat recovery boiler, and then steam is fed to steam turbine; exhaust gases of off-line boiler are conveyed to waste-heat recovery boiler or to atmosphere. Hot steam coming from waste-heat recovery boiler is mixed up with that produced in off-line boiler by separation process. EFFECT: improved economic efficiency and power capacity of combined-cycle plant at same capacity of gas-turbine unit due to joint evaporation of feedwater both in waste-heat recovery boiler and in off-line boiler. 2 cl, 3 dwg

Изобретение относится к теплоэнергетике и может быть использовано на тепловых электростанциях и нагнетательных установках. Изобретение позволяет повысить экономичность парогазовой установки и увеличить ее мощность при неизмененной мощности газотурбинной установки путем совместного испарения питательной воды как в теплоутилизационном котле, так и в автономном котле. Это достигается тем, что дополнительно осуществляют отбор части насыщенного пара из теплоутилизационного котла в автономный котел, его доиспарение и перегрев в последнем и теплоутилизационном котле и подачу пара в паровую турбину, причем выхлопные газы из автономного котла направляют в теплоутилизационный котел газотурбинной установки или в атмосферу. При этом смешение нагретого пара теплоутилизационного котла с генерируемым в автономном котле осуществляют посредством сепарации.The invention relates to a power system and can be used in thermal power plants and injection plants. EFFECT: invention makes it possible to increase the efficiency of a combined cycle gas turbine unit and increase its capacity with the unchanged power of a gas turbine unit by co-evaporation of feed water both in a heat recovery boiler and in a stand-alone boiler. This is achieved by the additional selection of a part of the saturated steam from the heat recovery boiler to an autonomous boiler, its evaporation and overheating in the last and heat recovery boiler, and steam supply to the steam turbine, and the exhaust gases from the autonomous boiler are sent to the heat recovery boiler of a gas turbine plant or to the atmosphere. In this case, the heated steam of the heat recovery boiler is mixed with that generated in the autonomous boiler by means of separation.
