Definitions

  • the present invention relates to a new chamber for pulsating combustion, said chamber having to allow the pulsating combustion of a mixture of fuel and oxidant.
  • the main chamber is provided with a set of lateral chambers, with a transverse plate dividing the main chamber into two compartments such as the mixture of fuel and oxidizer which enters the first of these compartments, in the direction of the transverse plate, is divided by this plate and is forced, to pass behind it, to pass through the lateral chambers.
  • the main chamber has four lateral chambers, distributed around the axis connecting the inlet orifice to the outlet orifice and the transverse plate is fixed to the walls of the chamber. This set is made in one piece during foundry operations.
  • German patent DE-AI-3 337 048 a pulsed combustion heating system or the combustion chamber can be made in two parts welded together.
  • a first object of the invention is to provide a combustion chamber which allows a simple realization and which, once assembled, does not present sealing problems.
  • a second object of the invention is to provide a combustion chamber which also solves the problem of differential expansion between the plate and the chamber.
  • the invention provides a new assembly for pulsating combustion comprising at least one pulsating combustion chamber in the form of a main chamber and at least two side chambers characterized in that it is constituted by at at least two shells shaped by stamping and connected together by welding, each of said shells comprising, at the level of the main chamber, fixing means constituted by stamped cavities in which a separation plate is adjusted with a minimum clearance allowing its transverse displacement .
  • said assembly also comprises at least part of a flat tubular exchanger and a connecting horn between said chamber and said part of the exchanger, it is then characterized in that it is produced in two shells which are assembled according to the general plan of the exchanger.
  • the assembly comprises the entire flat exchanger, this exchanger comprising a decoupling chamber into which open all the tubes of the tubular exchanger.
  • these fixing means consist of cavities produced during stamping where the intermediate plate can be mounted.
  • the combustion chamber comprises four lateral chambers distributed around the main chamber, each lateral chamber being located in the immediate vicinity of two other chambers, so that each wall of a chamber is substantially in contact with a wall of a neighboring chamber, the contact zone of these two walls each defining a part of the wall of the central chamber, and the cavities are located in said parts of the wall of the main chamber.
  • FIG. 1 shows an assembly (1) produced according to the invention. It comprises a combustion chamber (2), a flat tubular exchanger (3), of which only the upper part has been shown.
  • the cham combustion flue (2) and the tubular exchanger are connected together by a horn (4) establishing a passage for the combustion gases.
  • the combustion chamber (2) has four lateral chambers, such as (5) and a central chamber (6) located between the inlet pipe (7) and the horn (4).
  • FIG. 2 is a half top view of the chamber (2). Between the lateral chambers such as (5), (5a) and (5b), the upper walls (10) and (11) of the pinched areas are shown. As it appears better on the section of FIG. 3, each upper wall such as (10) and (11) is associated with a lower wall such as (12) and defines with it the housing (14) in which is housed the separation plate (13).
  • the extension (14) has the shape of a cavity produced by stamping.
  • Each side chamber such as (5) and (5a) has side walls (51, 52, 53 and 54), or also (54a).
  • the consecutive walls (53) and (54a) meet in the area (55) which partially defines the wall of the central chamber (6).
  • the housings such as (14) are located in the zone (55) and each extend between two consecutive walls (53 and 54a).
  • the plate (13) is adjusted so as to have a minimum clearance between its ends and the bottoms of the housings (14). According to the embodiment presented the contact between the plate and the housing (14) is almost linear but one could give any shape to the walls (10) and (12) which would allow a more or less extensive contact surface.
  • a firm fixing of the plate is thus obtained, but which allows transverse movements.
  • the plate can expand since under the effect of such expansion the walls (10) and (11) of the housings (14) will move apart.
  • the separation plate (13) After placing the separation plate (13) inside a half-chamber by insertion into the cavities (14) and (14a), the plate (13) is immobilized in one of the cavities by making a point Welding. The two stamped half-assemblies are then joined and welded to the wheel over their entire length according to a strip (25) shown in figure (1
  • the tongue (25) is removed and the connection is made by a TIG (Tungsten Inert Gas) weld which makes it possible to reconstitute a perfect cylinder. and simplifies the connection of the assembly thus obtained with the other members of the boiler. The assembly produced is thus perfectly sealed.
  • TIG Torsten Inert Gas
  • the exchanger (3) is advantageously produced, including a section along the axis VI. VI of Figure 5 is shown in Figure 6.
  • the edges (20) and (21) are welded by the same weld bead T.I.G. (30).
  • the two half-plates have been stamped so as to each define a series of half-tubes such as (31, 33) and (37, 34), each half-tube such as (31.37) being separated from the half-tube neighbor such as (33, 34) by a flat strip (35, 36).
  • a seam weld is made on each flat strip.
  • the decoupling chamber (32) consists of a cylindrical wall, a circular wall constituting a bottom and a connecting wall between the tubes and the interior of the chamber. It is perpendicular to the general plane of the exchanger.
  • the chamber is made like the rest of the assembly during the stamping of the half-plates and the bottom plate is attached and welded. It comprises a tube (50) for the outlet of the gases.
  • the advantage of such an embodiment is to have a continuous connection between the tubes and the chamber.
  • the central part (30) of the exchanger can have any shape and, for example, a shape could be provided such that the decoupling chamber is located below the chamber (5) and is not offset as shown in FIG. 4.
