Study of Feedforward Cascad Control of Boiler Superheated Steam Temper-ature Based on Radiant Energy Signal

Meng Xia

Abstract

The paper studies dynamic characteristic between the radiant energy signal in the furnace of plant boiler and superheated steam temperature. It puts forward a feedforward-backforward control system of superheated steam temperature based on radiant energy signal. By amending the spray control of cooling water and quality of superheated stream, the efficiency and security of thermal power can be improved.
