A burner is provided which includes a tile surrounding an opening of the tile extending along a burner axis, the tile including a front side and a rear side, wherein the rear side has an air inlet connected to the opening for feeding air into the opening, and the front side has a discharge outlet connected to the opening for discharging a flame into a surrounding area. The burner includes at least one oxygen lance extending along the burner axis in a first recess of the tile, and the oxygen lance having an ejection nozzle at an end region of the lance for ejecting oxygen, wherein the at least one oxygen lance is mounted with the ejection nozzle positioned along the burner axis to be adjustable between an uppermost position and a lowermost position via a zero-position in between the uppermost position and the lowermost position.

Low-NO-burner

A burner, particularly Low-NOx-burner, the method for generating a flame by combustion of a fuel, having a tile surrounding an opening of the tile extending along a burner axis, the tile further having a front side and a rear side facing away from the front side, wherein the rear side comprises an air inlet connected to the opening for feeding air into the opening, and wherein the front side having a discharge outlet connected to the opening for discharging a flame generated by the burner into a surrounding area, and wherein the tile further having an inside facing the opening as well as an outside facing away from the opening. The burner further has at least one oxygen lance extending along the burner axis in a first recess of the tile.

A method for the partial removal of contaminants such as nitrogen oxides from a process gas stream is described. The process gas stream is separated into at least two process gas streams by means of a partition, baffle, damper or other device. Ozone is fed into contact with at least one of the separated process gas streams to oxidize the contaminants therein and the at least one of the process gas streams contacted by ozone is fed to a scrubber for removal of the oxidized contaminants from the gas streams. The separation is proportional to the percentage removal of contaminants desired.
