  • Power from coal where to remove impurities, IEACR/82

    There is a lack of reliable and published data for making overall recommendations based on costs. It is also difficult to generalise, since coals vary widely in their properties. However, advanced cleaning technologies are likely to play only a limited role in optimising the removal of impurities from coal when used for power generation.

    Coal breakers also remove impurities from the coal (typically slate) and deposit them into a culm dump. The coal breaker is a forerunner of the modern coal preparation plant. Coal tipples typically were used at bituminous coal mines, where removing impurities was important but sorting by size was only a secondary, minor concern.

    18-07-2007· Some clean coal technologies purify the coal before it burns. One type of coal preparation, coal washing, removes unwanted minerals by mixing crushed coal with a liquid and allowing the impurities to separate and settle. Other systems control the coal burn to minimize emissions of sulfur dioxide, nitrogen oxides and particulates.
