COMBINED CYCLE GAS TURBINE POWER TRANSFORMER BASED ON SETTING HEAT steam injection into the gas path AND METHOD FOR ITS OPERATION

摘要

1. A method of operating a combined cycle plant with steam injection into the gas path, comprising: supplying compressed in a multistage air compressor to the combustion chamber (CC) GTU burning fuel into the CS feed gas mixture (ASG) of the gas turbine in a waste heat boiler (PKU ), and the generated steam - for injection into the gas path of a gas turbine and a steam turbine (PT) feeding the exhaust steam from the steam turbine for injection into the gas path of a gas turbine, further, after the FCCH, ASG over the surface heat exchanger-condenser (PTC) . hlazhdenie and condensation in the PTC contained in the ASG water vapor collection, diversion, handling and feeding the condensate to the FCCH, removal of ASG into the atmosphere, heat removal by the air capacitor, for example, cooling towers, characterized in that the cooling and condensation ASG is produced in a surface heat exchanger -capacitor (PTC), which is incorporated in a closed refrigerating circuit evaporator lithium bromide absorption heat transformer (ABTT) circulating through heat removal at this hladonositelyu.2 circuit. . A method according to claim 1, characterized in that in the summer include external heat dissipating path ABTT capacitor - absorber - cooling tower and adjust ABTT to work in chiller mode (ABHM) from the water-refrigerant temperature in the evaporator loop 12/7 ° C and temperatures water in the external circuit of the machine 28/36 ° C (± 5 ° C) (input / output), 3. The method of claim. 1, characterized in that in winter, during the heating season, include external heating circuit ABTT with independent heat exchangers for heating, in general, condensation of the PTC heating water and fuel gas and is adapted ABTT for Mode the heat pump (ALBHP) with
