| Abstract: | When the temperature of soot blowing steam is put into automatic mode,there are frequent fluctuations of spray control valve during the soot blowing process of 660MW Ultra Supercritical Boiler in a power plant and the spray control valve is seriously worn.This paper firstly analyzes the necessity of spray system design for the soot blowing system,secondly analyzes the reason of frequent fluctua・tions of spray control valve during the soot blowing when the temperature of soot blowing steam is put into automatic mode and spray control valve seriously worn,and the corresponding improvement meas-ures are proposed finaly. |
