| Abstract: | In order to improve the economy of running a direct air-cooled system,based on the thermodynamic model of an air-cooled system,the optimal back pressure has been analyzed theoretically with consideration of both the steam turbine power output and the fan power consumption.A parametric analysis has been conducted to investigate the influence of some key parameters on the optimal back-pressure,including the flow rate of exhaust steam in a turbine,the ambient temperature,and the current back-pressure.Thus,the results provide helpful guidance for the cold-end optimization and economical running of the direct air-cooled thermal power plants. |
