Control and method for operating a vaporizer burner

摘要

Formerly unpleasant blue smoke was generated in a vaporizer burner for auxiliary heaters for motor vehicles once the fuel supply was cut off and the flame died down, as the remaining fuel was merely heated up, but not burnt. According to the invention the glow plug is activated for a determined period of time during the after-running phase of the combustion air blower. By this means practically all remaining fuel is vaporized and burnt and therefore the forming of blue smoke and remaining residues in the area of the plug muff and/or the burner is avoided.
