Definitions
- the invention relates to an evaporation chamber for a heater operated with liquid fuel, in particular a vehicle heater according to the preamble of patent claim 1.
- the invention is based on the idea of improving the combustion and thus the emission and noise behavior of a heater equipped with a generic combustion chamber by skillfully designing and guiding the combustion chamber flame into the combustion chamber flame tube.
- Experiments carried out in the context of the invention have shown that different eccentric positions of a flame pinhole opening of unchanged area lead to considerably different emission and noise values.
- the most favorable measure of the eccentric arrangement of the opening and its circumferential position can be determined experimentally for a certain generic combustion chamber configuration.
- eccentricities of different sizes can be optimal. The the same applies to the circumferential position of the center of eccentricity.
- FIG. 1 shows a longitudinal section through a combustion chamber according to line I-I in Fig. 2,
- FIG. 2 is a view of the combustion chamber according to the arrow II in Fig. 1st
- the combustion chamber consists of a fuel-air mixing and ignition chamber area 1 and a flame tube 2 which adjoins in the direction downstream of the ignited mixture.
- the area 1 is formed by an outer tube 3 and an inner tube 4 lying concentrically in this and a flame perforated diaphragm 5, through which the flame tube 2 is connected to the area 1.
- the annular space lying between the outer tube 3 and the inner tube 4 is closed at the end opposite the flame orifice plate 5.
- the inner wall of the outer tube 3 is lined with a porous absorbent body 6. Liquid fuel, such as diesel fuel, is introduced into this absorbent body 6 at an introduction point 7 indicated by a dash-dotted circle. In the area of this discharge point, the ignition takes place when the burner is started.
- the combustion air is fed through the open end of the inner tube 4 opposite the flame orifice 5.
- the air flow into the inner tube 4 is swirled.
- the inner tube 4 is provided with a baffle plate 8 at its end facing the flame pinhole. Directly adjacent to this baffle plate 8 are radially open axial slots 9 in the jacket of the inner tube 4, which extend approximately over a third of the total length of the inner tube 4. Due to the swirl-like supply of the combustion air through the inner tube 4, the combustion air penetrates on the one hand through the slots 9 and through the opening of the baffle plate 8 into the mixing chamber. region of the combustion chamber, which extends around the inner tube 4 and is essentially formed by the annular space 10 between the outer and inner tubes 3 and 4. In the area between the baffle plate 8 and the flame pinhole 5, the burner flame forms during continuous operation of the burner, so that it can then fully develop within the flame tube 2.
- the opening of the flame pinhole 5 is a circular surface arranged eccentrically to the axis of the combustion chamber.
- the eccentric offset of the center of the flame pinhole opening lies in a direction through which the wall area of the flame pinhole 5, which adjoins the fuel introduction point 7, is enlarged.
- FIG. 2 The position of the combustion chamber shown in FIG. 2 corresponds to a horizontal operating position with a fuel introduction point 7 lying approximately at the height of the axis.
- the center of the opening of the flame pinhole is circumferential with respect to the illustration in FIG. 2 by about 45 ° twisted vertically below. With such a position of the opening of the flame pinhole 5, a compromise with respect to good emission and combustion noise values for different installation positions of the combustion chamber could be found in tests carried out.
- the operating positions suitable for this are the installation position shown in FIG. 2 and one with a position of the fuel introduction point 7 at the top in FIG Zenith and a vertical installation position with the flame tube lying vertically below.
- the outer diameter of the flame pinhole measures approximately 45 mm, the diameter of the diaphragm opening being 20 mm.
- the combustion air is introduced into the inner tube 4 with a swirl running in the direction of the arrow D.
