Abstract

The oil-fired burner assembly has at least one central spray jet and associated ignition, with a fan blower for the combustion air which is fed through the flame tube surrounding the spray zone downstream of the jet. Further spray jets (2) are at equal intervals round the central spray jet (3), within the flame tube (1). The central jet (3) is a mixing spray jet with an air feed, flame stabilizer and ignition. A ring disk body (4) is between the central jet (3) and the surrounding jets (2).
