Evaluation of Coal Burning Attrition in Large Power Stations and Development Trends of Governance Technologies
The coal burning attrition in large power stations include quantity attrition and heat attrition.Dust,rainwater infiltration and erosion,and low-temperature oxidation cause significant losses and environmental pollution in coal mines.By conducting fuel balance tests to evaluate the coal yard attrition,the coal burning attrition situation can be comprehensively quantified.Based on actual evaluation results,the maximum quantity attrition can reach 10 million yuan/year,and the maximum heat value attrition can reach 59 million yuan/year,coal yard attrition cause huge economic losses.In view of the issue of coal yard attrition,physical and chemical methods are adopted,as well as the use of composite inhibitors for coal attrition governance,resulting in an attrition reduction rate of over 93%.Through the application of compound inhibitors in power plants,it brings considerable economic and social benefits for power plants.
