  • Method for reducing pollutant gas emissions in combustion and burner therefor
    Patent number: 5503548
    Abstract: The invention relates to a process and apparatus for reducing pollutant gas emissions in the combustion of fuel, which utilize oxygen or oxygen-enriched air while avoiding the resulting disadvantages of high flame temperature and low gas momentum resulting in high NO.sub.x emissions. The invention provides a process of burning fuel, which simultaneously injects two jets of heated oxidant gas such as recirculated furnace gases and mixing such recirculated furnace gases with the oxidant into the furnace.
