Application and Practice of All-factor Coal Blending Technology
The main characteristics of coking coal used in Yun-gui-chuan and Shanxi are analyzed,and the difference between the predicted value and the actual value of coke production is compared from five aspects,including coal type,coal blending characteristics,ash content,vit-rinite composition and coke quality,by applying the all-factor coal blending technology and traditional coking blending technology.The aver-age deviation of CRI and CSR is-0.31%and-0.02%,respectively.The all-factor coal blending technology can predict coke quality and guide coking production well.Through the analysis of the reflectance distribution diagram,the coal blending plan optimized by the all-factor coal blending technology can effectively control and stabilize the quality of the coal blending,realize the thinning of the coal blending,the sta-bility of coke quality and the reduction of coke production cost.After production verification and operation data modification,the all-factor coal blending technology has a wide range of adaptability in side-loading tamped coke ovens,and can accurately predict the thermal properties of coke and chemical product yield,which provides an important technical basis for scientific and convenient determination of coal blending scheme.
