Abstract: Abstract:Through the adjustment experiment of the coal mill system, the relationship of the coal fineness and the energy consumption of the mills with the opening degree of the splitter, the loading force, the output and the air volume was investigated. The operation parameters of the mills were optimized. The equilibrium of the coal-air ratio of the mills and the pulverized coal fineness were improved. The experiments of changing primary air flow, changing oxygen, changing secondary air and tertiary air and changing the burner air distribution mode were carried out, and according to the experiment results, the influence of the boiler operation parameters on the boiler efficiency were studied. Based on above experiments results, the operation parameters of the unit were optimized and adjusted. The problems of the unit in its operation, which include high combustible matter content in fly ash and the high exhaust gas temperature, were solved. The safe and stable operation of the unit was ensured.
