Title:
MULTI-MODE COMBINED CYCLE POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2015/187064
Kind Code:
A3
Abstract:
This invention is intended for use in power plants with heat generation facilities. The design of a combined gas and steam power plant can also be used in the reconstruction of outdated cogeneration plants and in projected autonomous sources of heat and power. A heat-generating combined cycle power plant comprises at least one gas turbine having a waste heat boiler mounted in the exhaust gas duct thereof, a device for the supplementary firing of fuel outside the combustion chamber of the gas turbine, at least one steam turbine coupled to at least one waste heat boiler, and also a gas-fueled heater for heating condensate from the steam turbine, said heater being mounted in the gas pipe of the above-mentioned exhaust gas duct, downstream of each waste heat boiler. Characterizing feature: the device for the supplementary firing of fuel is configured in the form of two combustion chambers, one of which is mounted in the flue at the inlet to a waste heat boiler, while the other is mounted in the flue, downstream of the waste heat boiler and upstream of a gas-fueled condensate heater. The installation can operate in three modes: base mode; peak load shedding mode; and partial load mode. The invention provides improved flexibility, efficiency and reliability in the working of a cogeneration plant.
