1979 to sweeten the coal blends. It resulted in a decreased coke rate and higher blast furnace productivity in all SAIL plants. Since then there has been a gradual increase in the use of imported coals in coal blends of SAIL plants. In India, indigenous coking coals are divided in two broad categories, namely Prime Coking Coals (PCC) and Medium,12.2 Coke Production - US EPA,three major subprocesses: coal preparation and charging, thermal distillation and pushing, and byproduct recovery. 220.127.116.11 Coal Preparation And Charging For By-Product Coke Ovens - The coal that is charged to the ovens is usually a blend of two or more low, medium, or high volatile coals that are generally low in sulfur and ash.Selection of Coal for inclusion in Coal Blend in Coke,,The procedure described above for the selection of coal for inclusion in coal blend in coke making explains that there is a necessity to achieve a balance between the requirements of throughput, high coke quality, battery life, cost efficiency, and overall economics with an assurance of a consistent supply of the coals.
