Abstract
Abstract A vaporization burner operated by means of liquid fuel for heaters, especially motor vehicle heaters. The burner has a combustion chamber, into which combustion air can be introduced in a turbulent manner under pressure. The burner also has a vaporization body made of an absorbent material that is supplied with fuel and has an essentially flat evaporation surface that faces into the combustion chamber for vaporizing the supplied fuel prior to mixing with the combustion air. Situated in the combustion chamber is an electric ignition device for igniting an initial flame. In accordance with preferred embodiments, the ignition device is an essentially flat glow-type heating element which is disposed in a plane that is adjacent and parallel to the evaporation surface of the vaporization body.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
153 words
A vaporization burner for liquid fuel heaters that is operable in any orientation, especially motor vehicle heaters, comprising a combustion chamber having combustion air intake means for introducing air into the combustion chamber in a turbulent manner, a vaporization body made of a fuel absorbent material, said vaporization body being connected to a means for supplying liquid fuel thereto and having an essentially flat evaporation surface facing into said combustion chamber, for the vaporization of fuel supplied thereto for mixing with the combustion air, and an electric ignition device for igniting an initial flame, wherein the ignition device is a glow-type heating element which is disposed on the evaporation surface, wherein the vaporization body and the heating element are carried on a carrier that is mounted to the burner, said vaporization body and heating element being carried in such a manner that the vaporization body and heating element are replaceable as a unit.
