Abstract: A burner for liquid fuel in which a pressure atomizer jet is located concentrically in an air supply pipe. A potlike body is located between the discharge opening of the air supply pipe and the discharge opening of the burner jet. The body or member is opened towards the combustion chamber, and has a shell having radial openings and extending to the discharge opening of the air supply type for closing it. The potlike member has a bottom constructed as a baffle plate with a center opening and radial slots emanating from it. Upstream of this baffle plate, there is located another potlike member which encloses a space containing the atomizer jet and the ignition electrodes. The bottom of the other potlike member is penetrated by a pipe whose discharge opening is downstream of the ignition electrodes between them. The diameter of the rim of the other potlike member is smaller than the diameter measured by the outer ends of the radial slots and is larger than the diameter of the center opening of the baffle plate.
