Monitor, 2009), coal is “the most polluting fuel in terms of greenhouse gases and already accounts for 65% of India’s CO 2 emissions.” According to Couch (2002), India could “reduce CO 2emissions to nearly 45% of its present level using state-of-the-art technologies relating to coal quality , boiler/generator design, instrumentation and control, and high

DRY BENEFICIATION OF HIGH ASH NON- COKING COAL USING

Beneficiation of non-coking coals in India was not given due importance till last decade due to its low value or not being able to meet the cost of the process . About 73% of the non-coking coal is used by the thermal power plants containing high ash ranging from 40-50%. Recently, the Ministry of Environment and forest, govt. of India has made a regulation to use the coal having ash less than ...

Study of dry coal beneficiation in an Air pulsated ...

Thus, it is exigent to develop efficient dry beneficiation technology for coal. This paper presents a summarized assessment of performance of an Air Pulsated Stratifier with particular reference to Indian Coal. The study was carried out on coal samples having ash in the range of 30-33%. Response parameters considered for this study were ash reduction and yield of clean coal. Results are found ...
