ABSTRACT:
A liquid fuel burner head features an axially movable primary air assembly carrying a centrally disposed nozzle spraying fuel radially of the burner head. Primary air ports surround the nozzle and include means for progressively increasing swirl of the primary air as radial distance from the nozzle increases and for adjusting the location of flame origin. Metering of secondary air and adjustment of its direction of swirl are both accomplished rearward of the secondary air outlet, the primary air assembly moving rearwardly to increase the secondary air as firing rate rises. A simple metal, frusto-conical flame holder is secured to and spaced forwardly of the burner head.
