Temperature Difference Calculation of Heater Affection and Its Affection on Cycle Efficiency

LI Ze-bo, ZHANG Shu-xia (Anhui Chizhou Jiuhua Power Plant, Guichi 247100, China; North China Electric Power University, Baoding 071003, China)  
This paper constructs the affection model of temperature difference of heaters of 300 MW units on cycle efficiency based on the equivalent heat drop method and the q-γ-τmatrix. It is proposed that affection on the cycle efficiency is different depending on the different heater' s position in thermal systems. It is not suitable to select same value for all heaters, or select the same values in both high pressure and low pressure heaters.
