Patent number: 8789478Abstract: Provided is a dry distillation and gasification typed incinerator capable of saving time and fuels required for combustion aid. In a first phase when a waste material A stored in a dry distillation furnace 1 is ignited till a fire bed is formed, the dry distillation and gasification typed incinerator supplies air to the dry distillation furnace 1 through an air supply passage 13. When the waste material A is in a continuous combustion state (a second phase), the oxygen supply to the dry distillation furnace 1 is switched from the air supply by the air supply passage 13 to the concentrated oxygen supply by an oxygen supply passage 15.Type: GrantFiled: September 23, 2011Date of Patent: July 29, 2014Assignee: Kinsei Sangyo Co., Ltd.Inventor: Masamoto Kaneko

Patent number: 8784095Abstract: Techniques, systems, apparatus and material are disclosed for generating oxygenated fuel. In one aspect, a method of producing an oxygenated fuel from biomass waste for use in a combustion system includes dissociating the biomass waste to produce one or more carbon donors. The biomass waste produced carbon donors are reacted with an oxygen donor to produce the oxygenated fuel comprising oxygenated carbon. Reacting the carbon donors with the oxygen donors includes applying waste heat recovered from an external heat source to the reaction of carbon donors and oxygen donor. The oxygenated fuel is combusted in the combustion system.Type: GrantFiled: February 14, 2011Date of Patent: July 22, 2014Assignee: McAlister Technologies, LLCInventor: Roy Edward McAlister

Publication number: 20140182490Abstract: Disclosed here are example gasifiers for gasification of solid carbon fuel. An example gasifier includes a vertical vessel that includes feeding means for introducing a fuel at a top and along a first vertical axis in the vessel. The example vessel also includes a pyrolysis zone for pyrolysis of the fuel, a combustion zone for burning pyrolysis gases from the pyrolysis zone, a reduction zone for gasifying carbonized fuel from the pyrolysis zone and an outlet for collecting gases produced in the reduction zone. In addition, the example vessel includes a horizontal plate fixedly mounted between the feeding means and the pyrolysis zone for receiving and retaining the fuel introduced into the vessel. Also, the example vessel includes a movable pusher mounted between the feeding means and the horizontal plate, the movable pusher to push the fuel retained on the horizontal plate into the pyrolysis zone and positioned or positionable above the horizontal plate.Type: ApplicationFiled: March 4, 2014Publication date: July 3, 2014Applicant: Xylowatt, S.A.Inventors: Frederic Bourgois, Alexandre Bacq, Johan Klein, Michael Haube

Patent number: 8726818Abstract: To suppress the generation of clinker so as to prevent the generation of a burning trouble, ceramic particles 30 are covered over a porous plate 4 to form a fire bed 3. Woody pellets 31 are scattered on the fire bed and combustion air is ejected from the lower side of the porous plate so as to burn the pellets. At the time of discharging ash generated by the burning to a secondary combustion space on the downstream side together with an air current of the combustion air or combustion gas, the ceramic particle layers and the woody pellet layer are stirred by a stirring section 21, 22 to thereby break clinker of the combustion ash formed in the fire bed, whereby the growth of the clinker is suppressed and the generation of a burning trouble is prevented.Type: GrantFiled: July 22, 2009Date of Patent: May 20, 2014Assignee: Yazaki Energy System CorporationInventors: Shinji Tongu, Muneo Iwauchi

Patent number: 8671586Abstract: A method for using an apparatus for upgrading coal comprising a baffle tower, inlet and exhaust plenums, and one or more cooling augers. The baffle tower comprises a plurality of alternating rows of inverted v-shaped inlet and outlet baffles. The inlet and outlet plenums are affixed to side walls of the baffle tower. Process gas enters the baffle tower from the inlet plenum via baffle holes in the side wall and dries the coal in the baffle tower. Process exhaust gas exits the baffle tower into the exhaust plenum via baffle holes in a different side wall of the baffle tower. Coal that outers the baffle tower descends by gravity downward through the baffle tower and enters a cooling auger, where the dried coal from the baffle tower is mixed with non-dried coal.Type: GrantFiled: January 1, 2013Date of Patent: March 18, 2014Assignee: SynCoal Solutions Inc.Inventors: Harry E.
