Reformation of second air control system of boiler

Abstract

Abstract:

Abstract:Taking the second air control system of a 300MW unit boiler of Huadian International Laicheng Power Plant as example, aiming at the requirement of lowNOx combustion, the system was optimized. According to the problems occurred in operation process, the actuator of second air valve was reformed, and the control strategy of the reformed second air valve control system was adjusted. The result in this paper can be used as reference for lowNOx combustion reformation of similar unit.

Key words: Key words:second air, control system, lowNOx combustion, intelligent positioner, control strategy
