The DCS of Waste Heat Power Generation of Cement Plant Based on Fuzzy Control

The heat source of waste heat power generation of cement plant is the waste heat gas of cement rotary kiln. Influenced by the impact of cement production, the control system is complex, so the existing control scheme cannot make the satisfactory effect. Based on a thorough analysis of the existing control scheme and the reference to manual operation experience of on-site skilled operator, the paper puts forward an improved fuzzy three impulses control scheme that comes from the drum level control of waste heat boiler. The scheme reflects the smoke temperature of the interference change in the heat source side and the exhaust fanpsilas rotational speed in the kiln inlet. According to the waste heat power generation technology and control characteristics, we design a set of advanced DCS with the redundancy controllers. The practice shows that the scheme has a satisfactory effect.
