#0183;#32;1. RATIONALE FOR COAL BENEFICIATION. The intrinsic quality of Indian coal, along with the dominant practice of open cast mining, has meant that run of the mine (ROM) Indian noncoking coal contains a huge share of ash and other minerals. ROM coal typically has high ash content from 3050 percent and low calorific value (2,5005,000 kcal/kg).
Coal in India and South Africa is essentially similar, and therefore the Indian coal sector can benefit from the experience gained in the South African coal sector, Tuckey says. He adds that the Indian coal sector will now have to focus on fine coal beneficiation, a development that took place in the South African coal some time back.
The IEA Clean Coal Centre is delighted to announce its First Workshop on Coal Quality. The two day workshop is being cohosted by the Coal Preparation Society of India (CPSI) in the beautiful city of New Delhi, India, on 910 November 2016 at the famous Habitat Centre.
This webinar examines technical developments in coal beneficiation covering densemedia and dry coal treatment, and upgrading various technologies. Amid a global trend to use low quality, inexpensive coal, it is now recognised that feedstock quality is a
#0183;#32;Beneficiation of noncoking coal is gaining ground in India. It not only reduces the volume of inert content to be transported to the power plant and also lowers the wear in the boiler houses. For special applications such as the fuel for integrated gasification combined cycle plant (IGCC), the ash content in the coal should preferably be below 15 %.
#0183;#32;Coal beneficiation is the process of putting coal through a technical separation mechanism to reduce its ash content, and improve sizing, consistency and overall quality. This policy is anchored primarily on environmental considerations, and will have to be balanced with economic considerations to create a greater impact.
A noncoking coal sample of vitrinite type from India was ground to 44 #181;m (d80) and subjected to column flotation to improve its quality. The noncoking coal analyzing % ash, % volatile
Thermal coal, which is the mainstay of India''s power generation, contains as high as 50% ash. To meet the rapidly growing demand for thermal power, the transportation facilities need to be significantly expanded. Major routes of Indian Railways are currently saturated. Creation of transport infrastructure is expensive. Beneficiation of coal is known to improve its quality and consistency.
The coal quality is judged by measuring the gross calorific value, or the capacity of the coal to produce energy. Earlier, gross calorific value...

#0183;#32;Owing to its drift origin, Indian coal is of poor quality and often contains 3050 per cent ash when shipped to power stations. Over time, the ash content of Indian coal has increased with the depletion of good quality coal reserves, expansion in surface mining and mechanisation in coal mining.
