Solving Transfer Chute Plugging at Power Plant United States The Need A leading power generation company operating a 600 MW coal-fired power plant recently started using coal that contained more moisture and fines than what the plant was originally designed to handle. The plant had a system of belt conveyors that transferred coal from the yard to the fuel silos. There were some transfer points in this system where conveying was switched from one belt to another. This fine and moist coal began to cause major flow problems in the conveying system, which had tall drops and sudden changes in direction. Transfer points within the system would not always reliably move the material. Coal would build up in the chutes, decreasing the cross-sectional area and eventually plugging the chutes complet
