In order to overcome the problems that earlier apparatus and methods have experienced, a fluid injection apparatus for a furnace comprises: -a housing having a space therein and a discharge orifice (53) in communication with the space and a combustion chamber of the furnace (10); a lance (48) for oxygen disposed in the space and in communication with the discharge orifice (53), said lance (48) in particular being adjustably moveable within the space to control a flow of the oxygen and the air; and an inlet duct (54) for air in communication with the space external to the lance (53). A corresponding method of introducing oxygen enriched air into a regenerative furnace (10) is proposed, the method comprising: injecting oxygen to a top portion of a regenerator (18, 20) for the furnace (10) or to a combustion chamber of the furnace (10); and entraining air into the oxygen during the injecting and prior to the oxygen entering the regenerator (18, 20) or the combustion chamber, with hot ambient air (75) being provided from a region at an exterior of and proximate to the furnace (10) into the entraining air for mixing with the oxygen. |
