Systems and methods for de-icing of an entrance screen of a gas turbine, and for removing moisture of air inlet filters

摘要

It is a system for de-icing of a gas turbine is created. A branch line is connected to the invention with an intake screen. A first line is provided with a stage of the compressor and a first input of the mixer component. A second line is connected to the exhaust gas outlet and a second input of the mixer component. The second line is designed for the purpose of extracting exhaust gases, without to increase the pressure at the exhaust gas outlet. A third line is connected to the outlet of the mixer component and the branch line connected. A method for de-icing of a gas turbines - inlet screen comprises the determining a is - temperature at the entrance screen, and determining a desired - temperature at the entrance screen. If the is - temperature at the entrance screen is lower than the desired - temperature at the entrance screen, a first flow rate of an air - exhaust gas - mixture is calculated, which is necessary in order to screen the desired - inlet temperature to achieve. The method also includes the extracting an amount of exhaust gas from the turbine exhaust gas outlet - subsystem without increasing a pressure at the turbine exhaust gas outlet - subsystem, the extracting an amount of air from a compressor stage and the mixing of the amount of exhaust gas with the amount of air, so that an air - exhaust gas - mixture to be generated that is conveyed to the inlet screen.
