  • Patent number: 8117974
    Abstract: An apparatus for extracting energy from fiber introduced as a fuel into a vertically elongated combustion chamber having a suspension burner capable of projecting a flame down the axis of the combustion chamber with a heat collection surface located radially from the flame and below the burner, and an exhaust opening located below the flame and below at least a portion of the heat collection surface, in which the combusted fiber yields a mixture containing hot flue gas and molten ash above the exhaust opening and heat transfers therefrom to the heat collection surface prior to any substantial contact of ash to a surface of the combustion chamber, to yield a mixture containing warm flue gas and non-molten ash, that is thereafter cooled to yield a mixture containing cool flue gas and non-molten ash.

  • Patent number: 7889075
    Abstract: A detection system comprising a plurality of taut wire panels having vertical detection/sensor wires. The sensor wires are tensioned to position trigger plates associated one or more of the wires. Trigger plate movement causes an actuating means to indicate a sensor wire has been moved. In one embodiment, sensor wires and portions of the panel frame have similar coefficients of thermal expansion to substantially eliminate environmental expansion effects that may result in false alarms. Linked sensor wires on adjacent panel may signal movement of entire panels. Panels are monitored by panel controllers reporting to sector controllers that report to a central command computer that automatically numbers sector and panel controllers at start-up. Bi-directional communication enables alarms and system faults to be precisely located.
