Abstract
In a coal-fired power plant having an exhauster fan for delivering coal/air flow through a discharge chute to a combustion chamber and further having a riffle box in the discharge chute, a mixing device located in the discharge chute between the exhauster fan and the riffle box for causing heavy and light distribution regions of the coal/air flow from the fan to converge upstream of the riffle box, thereby mixing them into a more homogeneous flow. In a preferred form, the device comprises a plurality of concentric, inwardly-angled rings located in the discharge chute to cause the heavy and light distribution regions of coal/air flow to converge after passing through the rings.
