The German Power Plant To Improve The Condensation Unit Economic Analysis Based On Water Temperature

The power industry is the basic energy industry which is related to the national economy and the people's livelihood.However,with the increasing energy crisis and the continuous progress of energy saving and emission reduction,how to further improve the economy of the power plant has been paid more and more attention.In order to improve the economy of Chengde thermal power plant,this paper analyzes the different methods to improve the temperature of condensate water.From two aspects of regenerative cycle system and flue gas waste heat utilization system,the effect of improving the condensate temperature on the economy of the thermal power plant is explained.According to the operating characteristics and structural characteristics of the unit in Chengde thermal power plant,the relevant data required for the regenerative cycle are arranged and calculated,and the effect of the regenerative cycle system on the efficiency of the unit is analyzed.On this basis,the design and selection of the regenerative cycle system of Chengde thermal power plant is carried out.The coal quality of the designed combustion products in Chengde thermal power plant is analyzed,and the influence of different flue gas waste heat recovery methods on the thermal economy of the thermal power plant is discussed.Finally,according to the different operating characteristics of the unit in summer and winter,the heat network side is calculated.The economic calculation and thermal economic calculation of the design and transformation of the Chengde thermal power plant are carried out respectively,and the factors affecting the equipment after adding the low temperature economizer are analyzed.
