  • Reduction of combustion effluent pollutants
    Patent number: 5443805
    Abstract: Injection of additive such as ammonia or calcium compounds along with a small amount of hydrocarbon, preferably methane or natural gas, in a relatively high temperature region of the effluent stream for effectively reducing pollutants such as NO.sub.x and SO.sub.x. Preferably, injection is achieved by atomization of a liquid-form additive or additive solution with a small amount of gaseous hydrocarbon.

  • Combustion system for reduction of nitrogen oxides
    Patent number: 5411394
    Abstract: Low NO.sub.x burners for the combustion of gaseous, liquid and solid fuels. The fluid dynamic principle of radial stratification by the combustion of swirling flow and a strong radial gradient of the gas density in the transverse direction to the axis of flow rotation is used to damp turbulence near the burner and hence to increase the residence time of the fuel-rich pyrolyzing mixture before mixing with the rest of the combustion air to effect complete combustion.
