Rotary Drum Patents (Class 48/187)
  • Patent number: 12140307
    Abstract: A burner (1) for the production of synthesis gas, configured to feed a reactant stream and an oxidant stream into a reaction chamber, the burner comprising at least one cooled component (11, 12), wherein said cooled component comprises channels (20) to convey a cooling medium, a cooling medium header (24) and a cooling medium collector (25), wherein said channels, said cooling medium header and said cooling medium collector are integrally formed within said cooled component of the burner.

  • Patent number: 8845324
    Abstract: The invention relates to a device for controlling regenerative burners used as a firing device, particularly for iron and steel product heating furnaces or for radiating tubes for continuous strip steel processing lines, according to which the supply of at least one of the fluids involved in the combustion (fuel and comburent) is carried out through a rotary injector (12) rotating by means of a rotatable actuator (M) so as to supply fluid alternately to one and then the other of the burners (B1, B2), the rotary injector (12) being placed on the comburent inlet duct (6), particularly air, and is provided to partially obstruct the supply pipe (19.1; 19.2) to the burner (B1; B2) such that one portion of the fumes from a regenerator (2.2; 2.1) for the non-operating burner (B2; B1) is led to the operating burner (B1; B2) and such that the other portion of the fumes is discharged to the stack.

  • Publication number: 20110151389
    Abstract: An air-gas premixing device to be inserted into a low-NOx gas burner. The device comprises a ring nut adapted to rotate about a symmetry axis passing through its geometric center. The rotation of the ring nut causes: the rotation of a shutter for closing/opening an air-passage section for a fraction of the air from a ventilation group; and the rotation of a premixing pipe provided with an eyelet for the passage of a combustible gas; so that the air and the combustible gas are mixed in said premixing pipe to obtain a decrease of NOx emissions.

  • Patent number: 6132560
    Abstract: A rotary drum cooler having a shell for cooling particulate material (e.g. coke particles) wherein the volumetric capacity of the lifters within the shell which lift the material from the bottom of the shell to the exit thereof can be adjusted to thereby affect the exit parameters (e.g. temperature, particle size, etc.) of the cooled particulate material.

  • Patent number: 6039774
    Abstract: A self-sustaining system for converting organic waste feedstreams into usable solid and gas end products includes a plurality of interconnected retorts, an apparatus for flash pyrolyzing the feedstream to form intermediate gas and solid products, a source for introducing a water spray to refine and cool the intermediate products, a device for separating the gas product from the solid product and a device for regenerating, and thereby further refining, the solid product. In a self-sustaining process, wastes which would otherwise be landfilled are converted to an activated carbon product and a combustible gas mixture of hydrogen, carbon monoxide, and lower hydrocarbons.

  • Patent number: 5851246
    Abstract: A process and apparatus for gasification of organic materials (typically incorporated in domestic and industrial wastes, including auto shredder residues) to produce useful synthesis gas (primarily CO & H.sub.2) with effectively non-toxic ash residue by means of a preferably stoichiometric burner directed into a single stage reactor containing a tumbling charge thus heated to 650.degree. to 800.degree. C. (below the incipient fusion temperature of the charge) resulting in thermally cracking and gasifying the organic materials in the charge and reacting the complex hydrocarbons and gas evolved with the CO.sub.2 and H.sub.2 O generated by the burner by combustion of a fuel and oxygen-containing gas at a high flame temperature, typically 2500.degree. to 3000.degree. C.
