ABSTRACT:
A kerosene combustion device includes a burner body having a heated inner surface against which kerosene and combustion air are impacted, to cause the kerosene to be vaporized prior to being ignited. The kerosene is introduced into the burner body through a pipe having an outlet configured to cause the discharging kerosene to be spirally moved and to have its velocity and pressure suddenly reduced. The pipe extends through a venturi tube which conducts the combustion air. The venturi tube includes two tapers spaced apart along its longitudinal axis to cause the air velocity to be gradually increased. The burner body includes an opening into which the venturi tube extends. That opening is formed by an inwardly projecting portion of the burner body against which the venturi tube bears, in order to be stabilized thereby.
