ABSTRACT:
In a vapor burner for liquid fuel there is an electrically heatable gasifying chamber (1), a passage system (K) concentric therewith for supplying air of combustion, and a burner tube (26) which surrounds a combustion chamber (25) and is bounded at the rear by an annular closure wall (22). The gasifying chamber (1) is formed substantially by a central gasifying tube (2). Guide means (19) serve to produce an external annular eddy (31) of combustion gases that extends along the inside (33) of the burner tube (26) rearwardly at least over a section disposed axially in front of the mouth (23) of the passage system (K). An ionisation measuring electrode (35) placed in the backward flow permits the flame to be accurately detected independently of the flame front which changes with a change in the burner output. When the burner tube (26) glows, there is automatic re-ignition if the flame blows off.
