Abstract

PURPOSE:To narrow a space of a combustion chamber, to make heating of a heat dissipating plate uniform and to cope with a shape of the plate by mounting a diffusing plate in which its recess is directed toward a nozzle on a central inner wall of a porous metal plate on a front surface of a combustion cylinder. CONSTITUTION:An inner cylinder 3 formed of a refractory material is mounted on an inner wall of an outer cylinder 1 for constituting a combustion chamber 2, and a porous metal plate 4 is so disposed across an outer end of the chamber 2 as to close the chamber 2. The plate 4 is formed substantially circular, and a semispherical diffusing plate 6 in which its recess is directed toward a nozzle 5 is mounted at a center of an inner wall of the plate 4 by a bolt and a nut. A distance from the nozzle 5 to the plate 4 is designed to be shorter than a length of a flame. Thus, liquid fuel sprayed from the nozzle is deflected in its direction by the diffusing plate, and extended in a radial direction.

In such a conventional apparatus, since the fuel is sprayed toward the perforated metal plate, the combustion chamber space must be at least the length of the flame so that the flame does not fly out. I had to. In addition, when the fuel is sprayed laterally into the combustion chamber, it is extremely difficult to set the perforated metal plate to be heated uniformly because the combustion chamber space corresponds to the length of the flame. .. Further, in recent years, the design of the device has been emphasized, and heat sinks of various shapes have been demanded, but in the case of the conventional system, this request could not be met. Therefore, the present invention has been made in view of the above-mentioned drawbacks of the prior art. The space of the combustion chamber can be made relatively narrow, the heat sink can be heated uniformly, and various shapes of the heat sink can be accommodated. The purpose is to provide what is possible.

In the structure of the combustion chamber according to the present invention, the semi-spherical, cup-shaped or umbrella-shaped concave portion of the diffusion plate is installed in the substantially center of the perforated metal plate facing the nozzle. Fuel is deflected in direction by the diffusion plate,
Radially spread. As a result, the fuel can spread along the surface of the perforated metal sheet and heat the entire perforated metal sheet. Further, by installing a skirt on the outer peripheral edge of the diffusion plate, the fuel spray air flow deflected by abutting on the diffusion plate is directed to the radial direction because the skirt is extended substantially perpendicular to the plane. The spread is prevented and the spread does not spread sufficiently on the perforated metal plate. On the other hand, the portion where the skirt portion is not extended is not prevented from spreading in the radial direction, so that it extends sufficiently to the perforated metal plate. As a result, the spread of the flame is suppressed by the presence or absence of the skirt, so that the shape of the radiation plate can be matched.
