Zusammenfassung:	Horizontally arranged burners 100 for boiler furnaces are provided, wherein each burner includes a fuel nozzle surrounded by a secondary air outlet 123. The fuel nozzle 138 and the secondary air outlets 123 may tilt in tandem with respect to an air plenum supplying inner secondary air and a fuel carrier providing fuel. Also provided are outer secondary air buckets 152 that may independently tilt with respect to a frame connected to the air plenum. This arrangement can be installed as a retrofit in a conventional horizontal furnace system or in a newly built system. The fuel nozzle 138 and the secondary air outlet 123, and the secondary air buckets 152 may all tilt in unison or may all tilt independently. The tilting assists with optimizing a flame temperature profile within the furnace
