Collaborative Optimization for the Regenerative Heating System of a Steam Turbine Unit Considering the Steam Sources of Deaerator and Feed Pump Turbine

Abstract:

Based on the flow stages structure of steam turbine, the collaborative optimizing model for selecting turbine extracting openings and steam sources of deaerator and feed pump turbine has been established by means of stages combinational-searching. Taking a 600MW steam turbine unit for example, the validity of the model has been illustrated, and various optimization schemes have been obtained with different steam sources of deaerator and feed pump turbine. The results show that the standard coal consumption rate can be decreased by up to 0.78069g/kW·h when the extracting openings are fixed. And the standard coal consumption rate can be decreased by up to 0.93342g/kW·h when the extracting openings are optimized collaboratively. The optimization method has referenced value for optimizing and designing the regenerative heating system.
