Based on the average clean coal production rate, hourly samples represent 458 tons of coal, a daily composite (6.4 hr) represents 2,932 tons, and a Weekly composite is equivalent to 14,663 tons of clean coal. Results For much of the data acquired in this study, strong autocorrelation was indica- ted.
· The total estimated operating cost is $9.00/ton of feed coal including the cost of feed coal, chemical supplies, maintenance, and labor. A financial model was constructed using a spreadsheet to evaluate the project''s financial viability.
· The clean-coal industry''s bigger hurdle may be finance, which is drying up quickly in Europe and the U.S., mainly because the projects are so costly and complex. Investment in Coal …

· Hyderabad: The coal mining industry, like other industries in the country, produces waste which has adverse impact on the environment. The Singareni Collieries Company Limited (SCCL), however, continues to make key changes and investments in cutting edge technologies to modernise existing practices to address environmental concerns across the company areas.
COAL If we as a nation are to benefit in the future from our enormous, low-cost coal reserves, a variety of efforts are necessary to (1) develop and demonstrate new "clean coal" technologies; (2) reduce uncertainty over environmental regulation and allow electric power
Typical crushing and breaking devices are feeder breakers, rotary breakers, hammer mills, and roll crushers. Sizing. Different cleaning processes are used on different sizes of coal. Therefore raw coal entering the plant will be screened (sieved) into three or four sizes. Clean coal is rarely sized, except for some industrial markets.

The output is a calibrated model with informed discrepancy from reality and quantified uncertainty.
· With a current-sensing relay (CR), the operation of the crusher can be improved. In this case, when the crusher motor becomes overloaded, CR''s setpoint is exceeded, and 2M (the feeder conveyor''s starter) is temporarily de-energized. When the crusher processes the material, the current level drops, and CR restarts the feeder conveyor.
