Patent number: 6435139Abstract: A waste heat boiler for cooling hot syngas in heat exchange with water under boiling pressure, consists of an outer pressure shell (1) having a water space (2) filled with boiling water up to a predetermined fluid level (4) and a steam space (3) above it. In the water space (2), heat exchanger tubes (5) are arranged, through which the syngas to be cooled flows. Downstream from the heat exchanger tubes (5) is a superheater for superheating the saturated steam generated by the boiling water. This superheater is positioned at least partially in the steam space (3) above the fluid level (4) and has straight tubes (7), through which the syngas coming from the heat exchanger tubes (5) flows and around which the steam exiting from the water space (2) circulates.Type: GrantFiled: November 16, 2001Date of Patent: August 20, 2002Assignee: Borsig GmbHInventor: Peter Brucher

Patent number: 4836115Abstract: A down-draft, gravity fed, bio-mass, solid fuel burning stove or furnace comprises an upright cylindrical housing having a top cover and a fire resistant openable air-tight floor. Fuel drops onto the center of the floor through a central feed tube where it burns in the form of a truncated conical pile. A second tube surrounds the feed tube, defining with it an annular air intake passage for discharging an annular current of air downwardly on the burning fuel. A heat exchanger surrounds the housing and its inner wall defines with the housing a smoke passage for upward escape of the hot gases of combustion. Heat from the smoke passage heats the contents of the heat exchanger. A baffle in the smoke passage enhances heat transfer. The central tube and cover are removable as a unit.Type: GrantFiled: June 23, 1988Date of Patent: June 6, 1989Inventor: Charles E. MacArthur

Patent number: 4583495Abstract: A wood-type solid fuel fired water heater of modular construction includes a radiation heat transfer section or module in the form of a first annular or cylindrical side wall of refractory material. A water circulating first coil is embedded in the inner surface of the first annular side wall or cylinder to provide a partial water wall or water jacket in the refractory material. The first annular side wall defines the combustion chamber and locus of combustion for direct radiant heating of water in the first coil. The convection heat transfer section or module is formed by a second annular side wall or cylinder of refractory material positioned above the first annular side wall. A second coil for water circulation is mounted inside the second annular side wall but spaced from the inner surface for circulation of hot flue gas around the second coil for convection heating of water in the second coil.Type: GrantFiled: December 6, 1984Date of Patent: April 22, 1986Assignee: Board of Trustees of the University of MaineInventors: Richard C.

Patent number: 4385568Abstract: A solid fuel burning device having a combustion chamber and a heat exchange chamber. The two chambers are joined by a tunnel composed of refractory material through which hot flue gases pass from the combustion chamber to the heat exchange chamber, causing the tunnel walls to be heated to the point of incandescence. As the flue gases pass through the tunnel there is a substantial reduction in uncombusted material by pyrolysis. The tunnel has an outside wall adopted to transmit energy by radiation.Type: GrantFiled: December 1, 1980Date of Patent: May 31, 1983Assignee: Kerr Controls LimitedInventor: David Murray

Patent number: 4102279Abstract: A charging shaft in a furnace housing, communicating at its bottom with an adjoining combustion chamber, is topped by a sloping lid having an air-intake opening near its lower end, that opening registering with an underlying baffle defining with that lid a narrow rising channel for incoming air. Distillation gases evolving in the shaft, admixed with some of the entering air but prevented by that air from escaping through the channel, are recirculated through a port at the top of the shaft to an entrance near its bottom -- just above a horizontal grate -- by way of an adjacent duct provided with a lateral air inlet, the duct narrowing at that inlet into a constricted throat from which the recirculated gases are aspirated by the entering additional air. The connection between the charging shaft and the combustion chamber may be formed by an upright grill, or by a diverging passage accommodating an ancillary combustion device such as an oil burner.Type: GrantFiled: November 24, 1976Date of Patent: July 25, 1978Assignees: Stefan Hahn, Norbert Drescher, Firma Johann GroschlInventors: Rupert Groschl, Josef Groschl, Ludwig Groschl, Johann Groschl
