For chain and sloping grate systems, fuel is fed into a feed chute and dragged onto the grate. For units burning wood, a typical design uses a "windswept spout," where the combustion air injects the fuel above the bed and the fuel falls onto the bed. For units burning coal, a "paddle wheel" type of feeder puts the fuel onto the grate.
