  • Patent number: 4377117
    Abstract: A furnace for burning dry or wet wood waste products such as hogged bark and the like is provided with a grating therein comprised of aligned rows of bricks resting on supporting cross beams, with at least some of the rows of bricks maintained a uniform distance from other rows of bricks by spacers disposed between such spaced-apart rows of bricks. The furnace is charged by turbulent air entering both above and below the grating, with a select portion of such air being pre-heated. A temperature gradient is established between an area immediately beneath the grating and the area above the grating in the range of 2200.degree. F. and can be controlled by selected initial placement of the bricks and spacers to achieve an optimum cross sectional area for flow of heated, turbulent air through the grating to produce a temperature for efficient heating, drying and burning of wood waste products in an essentially pollution-free manner.
    Type: Grant
    Filed: August 11, 1981

  • Patent number: 4311102
    Abstract: An improved burning system for automatically controllably charging a wood-waste burning steam boiler utilizes a fuel bin unloader having a gravity fed screw metering device for feeding fuel into the system in response to steam demand and pollution output feedback signals. The metering device deposits fuel through a rotary air lock into an air stream of a fuel injection fan having a vortex controller on the inlet side to modulate and maintain a proper fuel-air ratio for wood firing. The fan injects the fuel and air into the boiler through a controlled proportioning valve. All controls and recording devices are contained in one control unit for operating each component of the system to achieve and maintain a proper fuel-air ratio according to received steam demand and pollution output feedback signals.
