Optimization of Coal Flow Control System in Coal Preparation Plant and Research on Customized Coal Blending Application
In response to the problems of low automation level,Large error in coal feeding amount,and large fluctuation of ash content index in the coal flow control system of Licun Coal Preparation Plant,an optimization plan for the coal flow control system was studied,and industrial tests were conducted on site to stabilize the concentrated coal index.The accuracy of coal blending can be controlled within about 1%of the detection accuracy of the ash analyzer(the range of blended coal ash content is 18%to 35%),reducing the labor intensity of workers and improving the concentrated coal yield,Furthermore,it has improved the economic and social benefits of the coal preparation plant.
