Economic Analysis of De-superheating Spray System Based on Thermal Economic State Equation

WANG Yan-jun,ZHANG Chun-fa,WU Yan-kun,HUANG Hai-dong(School of Energy and Power Engineering,North China Electric Power University,Baoding 071003,China)  
Taking introduced 300 MW generate sets for example,the effect on generating sets produced by super-heater and re-heater de-superheating spray is analyzed by utilizing the thermo-economy system state equations.According to the digital analysis,the effect on generating sets of super-heater spray de-superheating when the water from feed pump is not strong,and the super-heater spray de-superheating may be widely used in practice.While the effect on generating sets of re-heater spray de-superheating is much stronger than the effect of super-heater spray de-superheating,and the thermal efficiency will decrease obviously.It is found that the use of re-heater spray de-superheating should be avoided during operation.
