    Powdered Coal - an overview | ScienceDirect Topics

    Powdered coal is hygroscopic and it is normally suggested that it be used as soon after grinding as possible, to avoid compacting. Also damp powdered coal tends to stick to hoppers, feeders etc., thereby interfering with regular feeding. Another characteristic of powdered coal is its ash, with regard to amount, composition and fusion temperature.
