The system makes use of an existing building and consists of a Push Floor flat floor bunker area which is loaded from delivery trucks and maintained fully by a wheeled loader machine. The Push Floor discharges on-demand and at a controlled rate, across a disc screen via a series of chain conveyors and into the existing and re-positioned fuel bunker. From here the material passes through a rotary feeder into a blow line and directly to one of Aberthaw’s three PF boilers. The control system and cabling were included within the contract.
