The Optimization and Application Research on Power Plant Circulating Water Waste Heat Regenerative Thermal System

In the dissertation, the thermal efficiency of the power plant is improved when the waste heat and the condensate of the Power Plant Circulating Water (PPCW) is recycled and heated. However, the regenerative steam extraction system is deviated from the optimal design condition, which decreases the thermal efficiency. In order to achieve the maximum thermal efficiency- the maximum energy saving, the non-linear optimization method is applied by changing the ratio CC of the condensation water that goes into the heat pump and by altering the value of its refrigerant temperature rise At in the heat pump system, the methods of which reach the purpose of energy saving maximization for the thermal system. The above research methods and results cast light on the reformation and the operation of this thermal system applied by the thermal power units.
