  • Coal-Fired Thermal Power Plantan overview

    A common requirement with fly ash conveying systems at coal-fired thermal power plants is that the fly ash should be conveyed to an off-site location for onward disposal. It is not unusual for this to be a distance of at least 1 km. The problem with increasing conveying distance is that for a given air supply pressure the conveying-line pressure gradient decreases and so there has to be a
