Coal preparation, or beneficiation, is a series of operations that remove mineral matter (, ash) from relies on different mechanical operations (not discussed in detail here) to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.
• The prime technology of coal beneficiation has not been widely appreciated either by the coal or the power producers because they view the economic benefits in isolation to their own sector. By lowering the ash content of input fuel there is a definite reduction in the cost of coal and ashhandling system of conventional boilers due
Coal gasification is said to have greater efficiency than conventional coalburning because it can effectively use the gases twice: the coal gases are first cleansed of impurities and fired in a turbine to generate electricity. Then, the exhaust heat from the gas turbine can be captured and used to generate steam for a steam turbinegenerator.
