Patent number: 8591608Abstract: A gasifier includes a combustion zone where a gas is introduced and fuel is combusted and at least one sensor for measuring a predetermined condition in the gasifier. A grate subsystem contains the fuel and includes at least one grinding mechanism. A controller is responsive to the at least one sensor and controls the grinding mechanism by activating the grinding mechanism if the predetermined condition exists to reduce the collection of non-fuel products on the grate subsystem.Type: GrantFiled: September 29, 2009Date of Patent: November 26, 2013Assignee: MSW Power CorporationInventors: Matthew Young, Steven Anthony, Stephen Armstrong, Steven Chase

Patent number: 5947719Abstract: A grate plate construction for installation as part of a grate assembly in which free flowing material is supported for movement along a path while treatment gas flows upwardly through such material. The construction has a relatively thin carrier plate having a highly wear resistant upper surface mounted in a supporting frame having ribs and webs which form with the carrier plate channels through which treatment gas flows for passage through the material via slots formed in the carrier plate by a high-energy process. The construction is economical even though the carrier plate itself is formed from relatively expensive material.Type: GrantFiled: May 16, 1997Date of Patent: September 7, 1999Assignee: Krupp Polysius AGInventors: Otto Heinemann, Hermann Niemerg, Norbert Bredenholler, Ludger Brentrup

Patent number: 5816200Abstract: A steam generator apparatus which includes an enclosure comprising vertically extending front and back waterwalls joined by opposed spaced first and second waterwalls, The enclosure also includes a plurality of spaced vertically extending windboxes, each of the windboxes faces the interior of the enclosure. Each of the windboxes comprises a plurality of modules that are configured for installation at respective elevations, each of the modules being dimensioned and configured for shipment to the installation site. Some forms of the invention further includes a vertically extending truss assembly and the ignitor and auxiliary air compartments are supported on the truss assembly. Other forms of the invention include air ducting supplying air to air compartments and the truss assembly extends within the ducting. Still other forms of the invention may utilize the truss assembly without the modular windbox.Type: GrantFiled: December 23, 1996Date of Patent: October 6, 1998Assignee: Combustion Engineering, Inc.Inventors: Jeffrey S. Mann, Michael S. McCartney

Patent number: 5673636Abstract: A process wherein an incineration grate is tempered by a medium that flows therethrough. The grate has a number of hollow plates made of sheet metal. Each plate lies on the next underlying plate. A connection pipe is arranged on one side of each plate and a discharge pipe is arranged on the other side of each plate for the flowing medium. The individual plates are crossed by a plurality of tubular elements which open on the top side of the plates. Primary air is supplied to the materials to be incinerated through the tubular elements. Primary air supply is individually dosed to each tubular element.Type: GrantFiled: May 31, 1995Date of Patent: October 7, 1997Assignee: Doikos Investments Ltd.Inventor: Jakob Stiefel

Patent number: 4475468Abstract: An incinerator with a moving-bed stoker in which a chain conveyor is inclined in the direction of its movement and a plurality of fuel- or fire-bed members L-shaped in cross section are mounted on the links of the chain conveyor, whereby a step-like moving fuel- or fire-bed is defined. Each fuel- or fire-bed member comprises an upright or vertical plate and a horizontal plate and combustion air injection holes are formed through the upright or vertical plate so that the foreign matter such as ash, metal pieces or the like as well as the molten ash produced as the result of the combustion of waste with a low melting point can be prevented from falling through the combustion air holes into the stoker.Type: GrantFiled: May 16, 1983Date of Patent: October 9, 1984Assignee: Ishikawajima-Harima Jukogyo Kabushiki KaishaInventors: Tokihiko Ishikawa, Takehiko Motomura

Patent number: 4353315Abstract: A flexible, perforate grate, e.g. made of a mat of meshed metal chain links or wirecloth belting, is provided at intervals spaced across its length, with individually extensile/retractile supports. By coordinately extending and retracting the supports, the material fed onto the grate at one margin can be walked, rolled, tumbled and similarly redistributed and moved across the grate to the opposite margin, and, for instance dumped off the far edge of the grate into a residue collecting system. The grate may be basically horizontal, or it may have a general cascade-like tilt either forwards or rearwards. In one embodiment, the supports are seen each having a grate mat contact member which pivots during extension and retraction in order to further alter the shape of the grate mat intervening two adjacent supports.Type: GrantFiled: June 12, 1980Date of Patent: October 12, 1982Assignee: Akihiko HiroeInventor: Katsurou Hayashi

Patent number: 4268274Abstract: Apparatus for progressively burning biomass material comprising a retort defining a chamber, a linearly moving grate bed enclosed within the chamber with a space below and a space above for respectively supplying primary air to the lower side of the grate and for collecting gases generated by progressive distillation of the biomass material at the upper side of the grate. Primary air is supplied to the underside of the grate bed at different pressures lengthwise of the grate by a distribution chamber extending lengthwise of the grate of V-shaped cross section containing at its bottom a Venturi opening through which air is delivered to the distribution chamber from successive longitudinally-arranged plenum chambers which, in turn, are supplied with air through conductors connected to a primary air source, each of which contains a damper. The grate may be horizontal or inclined.Type: GrantFiled: July 9, 1979Date of Patent: May 19, 1981Assignee: Forest Fuels, Inc.Inventor: Robert A. Caughey
