equipment for the processing of brown coal

Pros & Cons Of Clean Coal Technology - Better Meets Reality

Some reports say that the future of clean coal might include gasification at one stage of the coal-for-energy process, which can help make electricity from coal more efficiently compared to pulverised coal (so, emissions aren't reduced per tonne of coal, but less coal might be used in total and there might be less emissions in total).
