Design and review of Millmerran coal handling plant

Abstract

[Abstract]: Millmerran Power Company generates 850 MW (mega watt) and produces electricity to about 1.1 million houses in the south-east Queensland. The Power Station consists of two generating units. The Coal plant at Millmerran Power Station has been experiencing difficulties with the transfer of wet coal in the plant. These problems have led to a reduction in the availability of coal plant and blockages in the silos. This blockage caused by wet coal has led to a considerable amount of unit trips. The identification and reduction of problems with wet coal is vastly advantageous as it would result in a reduction in the number of unit trips. Therefore Millmerran Power Station which operates as a private investor would benefit significantly from this improvement. A detailed review of the coal handling plant, conveyors and chutes was carried out. The solution was to connect the Reclaim conveyor to the Stacker conveyor system through a Reblending conveyor system. By using this method the coal can be stacked in the emergency area until it is dry enough for handling.
