BURNER UTILIZING OXYGEN LANCE FOR FLAME CONTROL AND NOx REDUCTION

摘要

A method of providing oxygen enriched fuel into a combustion atmosphere of a furnace includes injecting a fuel stream into the combustion atmosphere, and providing oxygen into the fuel stream during the injecting of the fuel stream into the combustion atmosphere. A fluid injection apparatus for a combustion atmosphere of a furnace is also provided and includes a housing having a space therein and a discharge orifice in communication with the space, a lance for oxygen disposed in the space and in communication with the discharge orifice, and an inlet duct for a fuel stream in communication with the space external to the lance.
