    Coal Drying Technology | Triple Innovation

    As a result, brown coal provides only 25% of the heating value of black coal, but has a low sulphur and ash content compared to black coals. Reducing the moisture content of brown coal by drying improves energy efficiency and reduces emissions ultimately producing a much more efficient black coal equivalent product.

    This is sent to a vacuum filter to recover most of the oil, then to a low-temperature evaporator to recover the remainder of the oil, leaving dry coal as the final product. The net result: additional recovered coal fines with lower ash and moisture content than has heretofore been possible. Here is a simplified schematic of the HHS process:

    What Is Clean Coal Technology? | HowStuffWorks

    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.
