Benefits of technology

[0009]The object of the invention is to overcome the described problems of the prior art at least in part and especially to enable reliable and low-emission starting behavior with little dense smoke in different installation positions.

Problems solved by technology

For the baffle plates of the prior art, which are made flat, this is among others not the case since depending on the temperature spontaneous changes of shape can occur which can adversely affect the combustion behavior of the burner.

Embodiment Construction

[0029]In the following description of preferred embodiments of the invention, the same reference numbers label the same or comparable components.

[0030]FIG. 1 shows a sectional view of the burner in accordance with the invention. The burner 10 in accordance with the invention has a nozzle 12 which is securely joined to the heat shield 24. The heat shield 24 together with a burner tube 40 which is connected to the heat shield 24 defines the combustion chamber 22. The burner tube 40 is surrounded by an outer pipe 42 which forms the burner flange. A flame tube 38 is attached to this outer pipe 42. The connections between the heat shield 24 and the combustion chamber pipe 40 or between the combustion chamber pipe 40, the outer pipe 42 and the flame tube 38 are generally welded connections. On the fuel nozzle 12, there is the fuel supply 50 which has a metal pipe 52 for supply of fuel and a fuel needle 14 for injection of fuel into the combustion chamber 22. Furthermore, in the region of ...

Abstract

A burner (10) for a heater, especially for use in motor vehicles, with an essentially axially symmetrical combustion chamber (22) and a baffle plate (36) which is located in the combustion chamber. The baffle plate (36) has a defined curvature in an axial direction and that there is a curvature in the direction of the burnout zone (32). An outer periphery of the baffle plate defines a plane and a maximum axial distance of the baffle plate from this plane Dm and the diameter of the baffle plate Bd have dimensions that have a ratio Dm:Bd relative to each other that is between 0.07 and 0.21.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The invention relates to a burner for a heater, especially for use in motor vehicles, with an essentially axially symmetrical combustion chamber, and a baffle plate which is located in the combustion chamber.[0003]2. Description of Related Art[0004]Burners of the initially mentioned type, which are also called atomization burners or spray burners, are used especially in auxiliary heaters and engine independent heaters for motor vehicles.[0005]There are numerous requirements for these burners, especially with respect to reliable and largely emission-free starting behavior and stable combustion operation. Furthermore, an effort is made to build heaters which can be used in different installation positions.[0006]With respect to starting behavior, various operating parameters must be matched to one another. On the one hand, it is necessary during burner starting to make available a relatively rich fuel-air mixture in the starti...
