Practice of Improvement Measures for Coal Charging Operation of 7 m Coke Oven in Bayuquan Branch of Ansteel
The current situation on the coal charging operation of the 7 m coke oven in Bayuquan Branch of Ansteel was introduced.And then in allusion to these problems such as excessive residual coal taken out by coal leveling during coal charging and coal-charging capacity being insufficient,the improvement measures of raising the coal leveling height of the coal leveling bar and optimizing the the particle size composition of blended were taken.After the measures were put into practice,the effective coal charging space of the coke oven increased by about 0.36 m3,the quantity of residual coal which was taken out by coal leveling decreased by about 30 kg each time,the proportion of blended coal smaller than 1 mm decreased by 3.860 percentage points,the bulk density increased by 15.04 kg/m3,the average coal loading in single-hole carbonization chamber increased,and the coal loading state of the coke oven was signifi-cantly improved.
