Operational Characteristic And Heat Economy Analysis Of Boiler Feed Pump Turbine

Steam power plant is a complicated thermodynamic system, the economical efficiency of operation not only depends on unit efficiency, but also correlates with mode of operation, auxiliary equipments configuration and efficiency of thermodynamic system. In the thesis, efficiency calculation of the power plant feed pump driving steam turbine in the unit operation is mainly analyzed, concerning the variant working condition economical analysis of this turbine. In this paper, through the analyses for the system of boiler feed pump turbine, created a computation model of feed pump and boiler feed pump turbine to make calculation for them. Through the result of pump and turbine thermal parameters in variant working conditions, analyzed the relation between the parameters and unit load, and economical efficiency of boiler feed pump turbine with different modes of operation, it is useful to the optimizing operation for the power plant.
