Ash Receivers


The centrifugal ash receiver has an important role in ash handling systems. Normally positioned on top or a silo or storage hopper, it performs the principal separation between ash particulates and the ash conveying air flow by means of cyclonic action (forces). The majority of ash particulates report to the lower apex cone of the receiver from which they can be directly discharged to the storage silo, or in the case of a vacuum ash conveying system, this transfer is performed using a double dump gate airlock valve as shown at the left. The airflow overflowing to the top of the receiver reports to a companion pulse jet type dust collector for final particulate removal from the conveying air stream.

National provides a variety of highly efficient, abraison resistant centrifugal ash receivers. For ease of replacement, these are of segmented. bolted design with all sections cast in NI-HARD having a minimum hardness of BHN 550 for maximum abraison resistance.

The photograph at the left shows a centrifugal ash receiver mounted above a National double dump gate airlock valve.
