Description Coke producers are facing a tough challenge to produce good quality metallurgical coke at reasonable price due to decreasing availability and increasing cost of good quality hard coking coal.The use of alternative carbon source like non-coking bituminous coal, heat altered coking coal (Jhama), petcoke can be a way to address the problem. In this article, the effect of preheating and stamp charging of coal on coke quality parameters were studied and compared with the properties of coke produced in top charging and stamp-charging process. The effect of coal preheating before compaction on the properties of resulting cokes has been studied using five different types of coals. Five coal samples with different coking properties have been selected for the study. The Coal samples have been preheated to their tarification level and then stamped for compaction to higher bulk density before carrying out high-temperature carbonization. The most significant differences between cokes from preheating then compaction were observed in terms of CRI and CSR value. Significant differences of properties have been observed between coke samples produced in preheating followed by stamp-charging and the coke samples produced in top charging and normal stamp-charging technique.
