OSTI ID:5419137
A fuel system is described for a boiler comprising inlet means for receiving the fuel, hopper means for storing the fuel, discharge means for discharging fuel to the boiler, first conveyor belt means extending between the inlet means and the hopper means and constructed and arranged for receiving the fuel from the inlet means and conveying the fuel to the hopper means, second conveyor belt means extending between the hopper means and the discharge means, a portion of the second conveyor means extending within the hopper means for receiving the accumulated fuel in the hopper means. The second conveyor means is constructed and arranged to transfer the fuel from the hopper means to the discharge means, first control means for controlling the speed of the first conveyor belt means in response to the amount of fuel in the hopper means, second control means responsive to the operation of the boiler for controlling the speed of the second conveyor belt means, sensing means for sensing the speed of each of the conveyor belts, alarm means connected to the sensing means for providing an alarm in response to the speed of the conveyor belt means falling below or above a predetermined value, and means associated with each of the conveyor belt means for controlling the level of the fuel on the belt means.
