Vaporization burner

Claim 2

A vaporization burner for a heater operated by means of liquid fuel, especially a motor vehicle heater, comprising a combustion chamber, an absorbent body situated for receiving fuel via a fuel connection and disposed on a carrier mounted in said combustion chamber, and air chamber means, disposed between the carrier and an end wall of the combustion chamber, for acting as a heat shield relative to surrounding parts that protects against the dissipation of heat from said carrier.

Claim 3

A vaporization burner according to claim 1, wherein said means for protecting comprises the carrier being supported on an end of the fuel connection in a manner such that it is suspended in the combustion chamber.

Claim 4

A vaporization burner according to claim 2, wherein the carrier is an essentially flat carrier disk which is disposed adjacent to and at a distance from said end wall of the combustion chamber.

Claim 5

A vaporization burner according to claim 3, wherein said end wall is a removable cover.

Claim 6

A vaporization burner according to claim 3, wherein a heat-resistant layer, made of a porous material, is provided as the absorbent body.

Claim 7

A vaporization burner according to claim 3, wherein the fuel connection extends through a part of the carrier that is located above a longitudinal center axis of the burner.

Claim 8

A vaporization burner according to claim 2, wherein a heat-resistant layer, made of a porous material, is provided as the absorbent body.

Claim 9

A vaporization burner according to claim 1, wherein a heat-resistant layer, made of a porous material, is provided as the absorbent body.

Claim 10

A vaporization burner according to claim 8, wherein the layer of porous material completely covers the carrier on a side facing into said combustion chamber.

Claim 11

A vaporization burner according to claim 1, further comprising combustion air supply means for delivering combustion air to said combustion chamber, said air supply means being constructed and arranged so as not to communicate with said air cushion means and to deliver the combustion air into the combustion chamber downstream of said absorbent body and carrier.

Claim 12

A vaporization burner for a heater operated by means of liquid fuel, especially a motor vehicle heater, comprising a combustion chamber, an absorbent body situated for receiving fuel via a fuel connection and disposed on a carrier mounted in said combustion chamber, and means for protecting against the dissipation of heat from said carrier to surrounding parts, wherein a heat-resistant layer, made of porous material, is provided as the absorbent body, and wherein the layer of porous material is provided with at least one opening which exposes an imperforate part of a major surface of the carrier facing the combustion chamber for enabling a thin fuel film to be formed on the exposed part and means for delivering combustion air to said combustion chamber so as not to communicate with the upstream side of the exposed part of the carrier.

Claim 13

A vaporization burner for a heater operated by means of liquid fuel, especially a motor vehicle heater, comprising a combustion chamber, an absorbent body situated for receiving fuel via a fuel connection and disposed on a carrier mounted in said combustion chamber, and means for protecting against the dissipation of heat from said carrier to surrounding parts, wherein a heat-resistant layer, made of porous material, is provided as the absorbent body, and wherein the layer of porous material is provided with at least one opening which exposes an imperforate part of a major surface of the carrier facing the combustion chamber for enabling a thin fuel film to be formed on the exposed part and means for delivering combustion air to said combustion chamber so as not to communicate with the upstream side of the exposed part of the carrier.

Claim 14

A vaporization burner according to claim 11, wherein the at least one opening is disposed in a central area of the carrier.

Claim 15

A vaporization burner according to claim 12, wherein the total area of the cross section of the at least one opening corresponds to up to 40% of the surface of the area of the side of the carrier facing the combustion chamber.

Claim 16

A vaporization burner according to claim 12, wherein said protecting means further comprises an air cushion formed between the carrier and an adjacent wall of the combustion chamber.

Claim 17

A vaporization burner according to claim 11, wherein the total area of the cross section of the at least one opening corresponds to up to 40% of the surface of the area of the side of the carrier facing the combustion chamber.

Claim 18

A vaporization burner according to claim 15, wherein said protecting means further comprises an air cushion formed between the carrier and an adjacent wall of the combustion chamber.

Claim 19

A vaporization burner according to claim 11, wherein the layer of porous material is free of openings in the area of a fuel inlet from the fuel connection.

Claim 20

A vaporization burner according to claim 17, wherein an ignition device is mounted in the combustion chamber in the area of the fuel inlet.

Claim 21

A vaporization burner according to claim 17, wherein said protecting means further comprises an air cushion formed between the carrier and an adjacent wall of the combustion chamber.

Claim 22

A vaporization burner according to claim 11, wherein said protecting means further comprises an air cushion formed between the carrier and an adjacent wall of the combustion chamber.
