Adjustable atomizing orifice liquid fuel burner

摘要

An adjustable atomizing orifice liquid fuel burner having two distinct mechanisms for changing flame characteristics, the first of which involves changing the liquid fuel spray pattern exiting the fuel nozzle and the second of which involves adjusting the atomizing medium flow properties out of the atomizing venturi. A liquid fuel tubular member having a liquid fuel tip sealingly connected to the outlet end thereof is concentrically disposed within an atomizing fluid tubular member, the atomizing fluid outlet end of which forms a venturi. The liquid fuel tip is adjustable in a longitudinal direction within the venturi formed by the atomizing fluid outlet end of the atomizing fluid tubular member. The liquid fuel tip further comprises means for imparting a swirl to the liquid fuel as it exits the liquid fuel tip.
