Abstract
It is fluctuant with a varied scope in coal-fired power plant as the different response characteristics of leading and retarded control, and economical efficiency and steady operation of unit plant can be affected directly by steam temperature. Through analyzing the influence factors and specialty of superheated steam, a new control strategy on introducing Radiant Energy Signal into circuitry of steam temperature is put forward. Simulation and in-suit operation has been carried out in a 300MW pulverized boiler power plant.
