Practical Exploration of Ash Transportation Intelligent Control Platform in Large-scale Thermal Power Plants
Based on the problems in the programmed control of the ash transportation system in a large-scale thermal power plant,this paper analyzes the large variations in unit load operation and the correlation between ash quantity in ash hoppers and the ash transportation system.By exploring the low-voltage working principle of the ash transportation system,an implementation plan for the intelligent control platform's supporting equipment is proposed.Specific improvement practices are carried out in four aspects:ash hopper level control,bin pump level control,unit interlock control,and automatic start/stop of air compressors.The analysis of the improvement effects shows that the system has achieved satisfactory operational results through the modifications,with improvements in both economy and safety.
