Abstract
A vibratory feeder in combination with a fuel fired furnace such as a coal fired steam generating boiler is disclosed. The vibratory feeder has a tray with a flat bottom in one embodiment and a step bottom in another and a hopper having vertical sides supported above the bottom so that the fuel in the hopper rests on the tray bottom and the vibration of the tray is transmitted into the stack of fuel thereby agitating it. The discharge end of the tray bottom directs the fuel from the feeder tray to the bladed distributor and water is directed onto the tray bottom to prevent caking of fuel on the discharge end.
