ABSTRACT:
A burner nozzle comprises an outer body (21) having a longitudinal hole (21a) therethrough. Screwed into the hole is a pin (27) applying by one of its ends against a vortex body (25) and pressing the latter into contact with the inner front side of a nozzle body (21) having a nozzle orifice (23a). The vortex body (25) is provided with channels which connect an annular cavity (43) surrounding the vortex body (25) to a vortex pocket (45). The pin (27) is provided with an oblong hole (27g) for the fuel supply. In the vicinity of the vortex body (25), this oblong hole (27g) communicates, through radial bores (27h), with another annular cavity (41) which is bounded by the inside surface of the outer body (21) and by an annular groove (27c) provided in the pin (27). The pin portion (27d) extending between the two annular cavities is provided with a circular row of grooves having a sectional area which is smaller than that of the vortex body channels. During operation, these grooves (27e) prevent dirt particles from passing to and clogging the channels.
