Application of the integrated automation system at Geliping Coal Preparation Plant

In order to step up the intelligent development process of the coal preparation plant, and respond to the national call for energy enterprises to make intelligent construction for enhancing their core competitiveness and innovation capabilities, the control system of washing processes in current use at Geliping Plant is switched to an integrated automation system through upgrading, based on results of investigation, analysis and demonstration, and the present state of the washing and control systems in current operation. Field application of the integrated system shows that the successful use of the system has made it possible for the plant to fully realize intervention-free routine production operations and shift the post-area operation mode to a mode that puts all-plant operations under centralized control; and its use has led to rise of yield of clean coal, consistency of product quality, reduction of accident rate and cut of equipment accident breakdown repair time, bringing for the plant favorable social and economic benefits.
