  • fly ash handling system by Macawber Beekay

    Vacuum system envisages conveying of dry fly ash from ash hoppers by vacuum pumps and collection in ISH. Each vacuum pump dedicated to a stream can convey both coarse and fine ash. The vacuum conveying system operates so as to allow sequential ash discharge from ash hoppers into conveying stream which is in continuous operation.
