  • Furnace heat absorption control
    Patent number: 4316420
    Abstract: Furnace performance is controlled during start-up or very low load operation at a time when the minimum air flow required to be supplied to the furnace is significantly greater than that required to burn the fuel being supplied to the furnace. Decreased furnace heat absorption is accomplished by supplying a larger quantity of the air immediately adjacent the fuel input location for the purpose of diluting the combustion gases and immediately decreasing their temperature level. Increased furnace heat absorption is obtained by introducing a greater portion of the air flow into the furnace at a location remote from the fuel being burned so that the gases at the fuel location remain at a high temperature, and transfer heat to the walls, before being diluted by the incoming air.
    Type: Grant

  • Cooling means for a water-filled ash hopper
    Patent number: 4213402
    Abstract: An ash removal system for a coal-fired boiler, where the temperature of the water in the ash hopper is maintained at approximately 140.degree. F. under all operating conditions of the boiler, by running cooling water through heat exchange surface positioned in the ash hopper. The cooling water, after picking up heat, is passed through heat exchange surface located outside of the ash hopper, before being introduced into the ash hopper. Some of the heated cooling water can be used as low level heating fluid around the plant site, if desired.
