METHOD OF WORK combined-cycle plant

摘要

1. CCP work method consists in the fact that air is compressed by air compressor with intermediate cooling, which is fed to the combustion zone of the combustion chamber into which fuel is fed simultaneously formed combustion gases are mixed in the mixing zone of the combustion chamber with the secondary cooling water with steam to give the outlet of the combustion chamber gas mixture that as the working fluid is directed at turbine combined cycle in which the gas-vapor mixture flow energy is converted into mechanical energy of rotation of the rotor Turbie us, more water vapor is partially condensed in a vacuum condenser, a vacuum which is created a vacuum compressor, the discharging is not condensed gaseous combustion products, condensed water is heated in the primary and secondary heat exchangers of the intermediate cooling air, and also in heats up the cooling heat exchanger the gas-vapor mixture leaving the high turbine pressure exchanger and cooling the exhaust gases, the cooling heat exchanger reheated vapor mixture at the outlet of the turbine High pressure is in the form of two series-mounted exchangers: the heat exchanger hot gas mixture and a heat exchanger cold-vapor mixture, in a further heat exchanger of the intermediate cooling air is fed only part of the water output from the heat exchanger cooling the flue gas, the remainder of the water is fed to the input of the heat exchanger cold-vapor mixture, and the input of the heat exchanger the hot vapor mixture fed to the heated water / steam from the outputs of the primary and secondary heat exchange
