摘要:
In order to overcome the problems that earlier methods and apparatus have experienced, in particular in order to provide for a method and burner producing NOx lower than 850 mg/Nm 3 at eight percent O 2 with adjustable flame shape and with higher heat transfer, it is proposed to provide oxygen enriched fuel into a combustion atmosphere (70) of a furnace (60), comprising: - injecting a fuel stream (32, 132, 232, 332, 432, 532) into the combustion atmosphere (70); and - providing, in particular injecting, oxygen (17, 117, 217, 317, 417, 517) into the fuel stream (32, 132, 232, 332, 432, 532) during the injecting of the fuel stream (32, 132, 232, 332, 432, 532) into the combustion atmosphere (70).

In order to overcome the problems that earlier furnaces and methods have experienced, in particular to provide for a furnace (10) as well as for a method enabling an effective use and symmetrical melting of the glass melt, it is proposed to heat an atmosphere in a combustion chamber (22) of the furnace (10), comprising: - firing a first plurality of lances (32, 33) from a first side of the furnace (10) into the combustion chamber (22) proximate a charging end (14) of said furnace (10), said firing of the first plurality including at least one stream of fuel and at least one stream of oxidant; and - firing a second plurality of lances (34, 35) from a second side of the furnace (10) opposite to the first side into the combustion chamber (22) proximate the charging end (14), said firing of the second plurality including at least another stream of fuel and at least another stream of oxidant.

In order to overcome the problems that earlier methods have experienced, a method of introducing oxygen enriched air into a furnace is proposed, the method comprising: - injecting oxygen to a combustion chamber of the furnace (10); and - entraining air into the oxygen during the injecting and prior to the oxygen entering the combustion chamber. A corresponding 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).
