Analysis and Treatment of Low Ammonia Pressure in 330 MW Boiler Denitrification System
Reasons of frequently occurred low ammonia pressure at the inlet of evaporator during the operation of 330MW Boiler SCR denitrification system in Guohua Huizhou power plant,are analyzed,which reduced the efficiency of denitrification.Measures to solve the problem by the operation manipulation are proposed,which resumed the ammonia pressure at the inlet of denitrification evaporator to its design value.Control measures has been made and executed based on the analysis of impurity's chemical component and occurrence reason in the evaporator,which guaranteed the stablilty operation of denitrification system.
