Abstract:
A burner for liquid fuel comprising:a burner pot including a vaporizing chamber; an atomizing element in the vaporizing chamber for atomizing liquid fuel; an electric heating device for start up heating said vaporization chamber to therewith vaporize the atomized fuel therein; a cylindrical flame retention baffle on the vaporizing chamber, the retention baffle having a lateral surface with holes therein; a fan for supplying an air flow through said vaporizing chamber for mixing of heated vaporized fuel in said air flow and delivery of a combustible fuel/air mixture into said retention baffle, a flame forming outside the retention baffle at the lateral surface of said retention baffle when the combustible mixture is ignited producing a flow of hot exhaust gases; means for deflecting a portion of said hot exhaust gas flow in a flow direction to heat the vaporizing chamber from an outside thereof to provide a desired temperature value of at least 350Â° C. in said vaporization chamber, and a temperature sensor attached to a wall of said burner pot for sensing a temperature in said vaporizing chamber and outputting a signal of sensed temperature value so that when a temperature in said vaporizing chamber exceeds said desired temperature value said electric heater can be switched to a non-operating state.
