Abstract
In a combustion apparatus including a burner head unit for burning a mixture of fuel in a gasified form or in atomized particles and primary air to form a flame, a secondary air ejecting nozzle communicating with secondary air passages functioning as means for cooling the burner head unit is located in the central portion of the burner head unit for injecting secondary air into the central portion of the flame in a stream parallel to the longitudinal axis of the flame to facilitate incorporation of the secondary air in the frame, thereby increasing combustion efficiency and widening the combustion range.
