Abstract
A method for carrying out combustion in a combustion zone using oxygen or oxygen-enriched air as the oxidant wherein atomized liquid is provided to the combustion zone separate from oxidant and combustible vapors, causing it to be distributed throughout the combustion zone and then, especially after its vaporization, uniformly provided to the combustion reaction with consequent uniform temperature moderation, and resulting in reduced NO.sub.x generation and reduced refractory damage.
Claims20
A combustion process comprising:
- (A) providing combustible vapor to a combustion zone:
- (B) providing oxidant, having an oxygen concentration of at least 25 percent, into the combustion zone separately from the provision of said combustible vapor at a high velocity sufficient to establish recirculating matter within the combustion zone;
- (C) providing atomized liquid into the combustion zone separately from said oxidant and said combustible vapor to provide coolant to the combustion zone and mixing coolant with recirculating matter;
- (D) mixing resulting coolant with said combustible vapor and/or oxidant;
- and
- (E) combusting the resulting combustible vapor with the resulting oxidant.
