Optimization studies on a coal preparation plant

ABSTRACT

Large-scale diversion of Indian coking coal to the non-metallurgical sector has been pointed out by the authors and others on various forums. One of the principal reasons, indeed, is the lack of coal preparation facilities to treat the entire quantity of raw coking coal to make it suitable for coke making. However, the poor capacity utilization of the existing facilities and poor organic efficiency are the issues that, if addressed properly, can change the whole coal-washing scenario in India. Having carried out systematic studies on the performance of some of the coking coal washeries in Jharia coal field, authors are of the opinion that the problem cannot be solved entirely by focusing only on technical aspects. Meticulous resource planning, staffing, and change in management strategy are as important as optimizing operational efficiencies. Hence, the authors have delved into all the aspects of a working coal preparation plant and identified several measures to improve its performance.
