Bowl mills are used for pulversing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in coal bunkers.The Amer 9 plant utilizes both direct and indirect co-firing configurations. The plant co-fires biomass pellets up to a maximum of 1200 kt yr −1, generating 27% by heat through two modified coal mills. Only wood-based fuel has been used since 2006, due to reduced subsidies for agricultural by-products.
