Abstract:

This paper described coal blending with coking coal,1/3 coking coal,fat coal,lean coal and long-flame coal,with bulk density of 0.7g/cm3 and 1.0g/cm3 and analyzed the impact to coke behavior under different bulk densities and different adding amount of low rank coal by using 2kg testing coke oven for analysis of cold strength and thermal property of coke.The results show that the cold strength and thermal performance of coke get worse after blended with low\|rank coal,and it changes less when blended with low\|rank coal less than 5%,but it can be improved by increasing the bulk density of blended coal.
