  • Patent number: 6910878
    Abstract: Process heaters operated with a burner that uses high-oxygen oxidant gas instead of air and that recirculates and entrains combustion gases, wherein oxidant gas is injected at an angle to the fuel nozzle.
    Type: Grant
    Filed: June 19, 2003
    Date of Patent: June 28, 2005
    Assignee: Praxair Technology, Inc.

  • Patent number: 6565010
    Abstract: A method for atomizing a fluid wherein a gas is heated with the heating facilitating the acceleration of the gas to a high velocity. The accelerated gas contacts the fluid transferring shear, pressure and inertial forces and heat to the fluid effecting efficient atomization of the fluid.
    Type: Grant
    Filed: March 24, 2000
    Date of Patent: May 20, 2003
    Assignee: Praxair Technology, Inc.
    Inventors: John Erling Anderson, Lawrence E. Bool, III, Glenn William Arnold, Christopher Brian Leger
  • Patent number: 6471937
    Abstract: The invention comprises a reactor having a source of a first hot reactant gas, a mixing chamber in which said first hot reactant gas mixes with a second reactant gas to form a reactant gas mixture, but wherein substantially no reaction takes place and a reaction zone wherein said mixture undergoes vapor phase reaction. A process for using the reactor is also disclosed.

  • Patent number: 6450108
    Abstract: A system for combusting difficult to combust fluid such as waste fluid wherein fuel and gaseous oxidant combust in a hot combustion gas chamber to form a hot combustion gas mixture which is accelerated to a high speed and at a steady, i.e. non-pulsing, flow is then used to atomize and then combust the fluid.

  • Patent number: 5762486
    Abstract: A method for combusting low heating value liquid by forming a toroidal vortex between atomized liquid and medium velocity oxidant, and carrying out combustion within the toroidal vortex to serve as a dependable ignition source for the main combustion reaction.
    Type: Grant

  • Patent number: 5752452
    Abstract: An improved apparatus and method for efficiently processing material, e.g. incinerating waste material, particularly dewatered waste water sludge, in a multiple hearth furnace by injecting high velocity jets of oxygen into the heating or drying zone of the furnace to augment turbulent gas-phase mixing, to aid in the burnout of carbon monoxide and hydrocarbons in the gas phase to achieve lower emissions, to increase convection over the drying sludge to increase its drying rate, and to ignite the drying sludge to further increase its drying rate. The apparatus and method provides an increase in sludge throughput and a reduction in carbon monoxide, nitrogen oxides and hydrocarbon emissions.
