Zusammenfassung:	Horizontally arranged burners for boiler furnaces are provided where each burner includes a fuel nozzle surrounded by a secondary air outlet. The fuel nozzle and secondary air outlets 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 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 and secondary air outlet, and secondary air buckets may all tilt in unison or may all tilt independently. The tilting assists with optimizing a flame temperature profile within the furnace
