PEAK POWER GENERATION PROCESS AND COMBINED-CYCLE PLANT FOR ITS IMPLEMENTATION Russian patent published in 1997 - IPC

FIELD: electrical and thermal engineering. SUBSTANCE: combined-cycle plant has inlet unit, compressor, combustion chamber, gas and steam turbines, all arranged in tandem; heat exchanger is placed at steam-turbine outlet in exhaust unit. Additional combustion chamber with steam superheater is installed between gas and steam turbines. Steam superheater is mounted inside it along its axis and made in the form of flame tube with conical nozzle at outlet. Contracting outlet of additional combustion chamber forms, together with conical nozzle of superheater, steam-gas ejector at inlet of steam turbine which is connected to load through shaft passed via exhaust unit. Combined-cycle plant is equipped with automatic-control system for fuel supply to injectors, main and additional combustion chambers, and water controller. EFFECT: facilitated power generation process. 2 cl, 3 dwg
