Application and Optimization Control of GCH System
In view of energy saving and emission reduction,the GCH used in reconstruction project of thermal power plant could recover the waste heat from boiler flue gas.Based on the case study of the 300MW unit in one power plant,this paper outlines the GCH reconstruction project with the designed GCH system control function.In combination with the DCS logic configuration and the on-site commissioning work of GCH control system,covering cold test,hot commissioning and optimal adjustment test,the problems of the reconstruction project are analyzed,and the GCH system flue gas temperature regulation is optimized.Thereupon,the cascade PID control combined with fuzzy control is explored into.The obtained research results have important significance and engineering reference value for improving the performance of GCH control system.
