Coking Coal Produced by Coal India Ltd
“Coal being a very important source of energy for industries like steel, cement, fertilizers and chemicals, it has an increased value in modern days. In order to satisfy the growing demand for coal, coal washing has become an integral part of the industry that is required to produce less moisture and ash-based coal to abide by strict environment regulations” says Padmesh Gupta , MD, Gupta coal.
In Regard to Thermal Coal
Thermal coal constituents nearly 87 percent of the total coal reserves of 264.5 billion tons the country is bestowed with. However, nearly 65 percent of it falls under E,F & G categories which would need washing before it can be efficiently fired in pulverized fuel power stations. The washing of Indian thermal coal poses many challenges and this paper highlights some of them and what are the technical solutions available to mitigate these.
Technology for washing-Padmesh Gupta
“While selecting the ‘water based technology’ we must keep the ease or difficulty of separation bases on the NGM of the coal at the separating density. The Bird’s Scale of Classification, given below, can be used to guide the selection process.The analysis of the Float and Sink data provides the relevant information on the NGM at the density of cut to achieve the desired product ash.
