  • Distributive integral gas burner
    Patent number: 5961321
    Abstract: A burner apparatus useful in steam producing or waste heat boilers. The apparatus includes a fuel delivery means placed between two airfoils that define an elongated venturi throat. The airfoils may be provided with a plurality of perforations to allow a secondary gas (ambient air and/or spent flue gas) to be supplied to the venturi throat for reducing NO.sub.x production.

  • Gas stabilized reburning for NO.sub.x control
    Patent number: 5890442
    Abstract: A coal-water slurry liquid fuel or coal or other liquid fuel is atomized for combustion in the reburn zone of a boiler with a relatively small addition of natural gas to produce NO.sub.x reductions comparable to the reburn effect of natural gas alone as well as a more uniform temperature profile in the upper combustion zone of the boiler.
