Abstract

In the face of dwindling reserves of scarce prime coking coals there is an escalating demand from the expending iron and steel industry for supply of metallurgical coke of stringent specifications for large capacity blast furnaces. This paper stresses the need to ensure adequate crushing of component coals and thorough blending of matching coals for the production of good quality coke. Results of investigations carried out in the Central Fuel Research Institute on the scope and effect of blending, extent of improvement in coke quality that can be obtained by adoption of finer crushing, selective crushing, stamp charging, dry charging have been discussed. The advantages of partial briquetting and preheating of the coal charge have also been described. Results of recent blending tests carried out with indigenous coals from newer sources as well as blends using imported coals have also been presented.
