この発明は燃焼器の高速燃焼に特に適した燃焼

Such combustors can be used primarily as heat treatment, heating or annealing furnaces in the mechanical industry, the steel industry and the non-ferrous metal industry.

る。 The lifespan of ceramic combustion chambers, which are especially used for high-speed combustion in combustors, depends on the high temperatures to which the combustion chamber is exposed,
Limited by the high heat exchange rate associated with combustor ON-OFF control. As a result, the combustion chamber must be replaced relatively frequently, resulting in extended furnace outages and increased maintenance costs.

ら作るのが好ましい。 Known combustion chambers include a hollow fitting member that is retained in the combustor body and surrounds the nozzle. Such a mating member is preferably made from a material that can withstand higher heat than the rest of the combustion chamber to save on material and repair costs.

虞れがある。 The combustion chamber disclosed in U.S. Pat. No. 3,320,999 consists of a body and a hollow ceramic fitting disposed inside a metal casing. In order to replace the fitting member, it is necessary to remove the entire combustor including the combustion chamber from the equipment, which results in extended downtime and increased repair costs. Furthermore, since the ceramic combustion chamber is rigidly attached to the metal casing, the combustion chamber is subject to large mechanical stresses due to thermal expansion of the combustion chamber due to high temperatures, which may result in damage to the combustion chamber.

る。 In the combustion chamber disclosed in GB 206983, a body made of refractory brick surrounds a tunnel which tapers towards its entrance and widens at the entrance of the tunnel. A mating member exhibiting a tapered exit nozzle is provided at the exit end of the tunnel. The mating member is aligned with the centerline of the tunnel and is connected to the tunnel casing by a heat resistant material. The high temperature and high rate of heat exchange in this known combustion chamber results in a loose connection between the mating member and the body. As a result, if the pressure in the combustion chamber becomes excessive or the device vibrates,
This causes the mating member to become dislodged from its home position at the exit of the tunnel. This disadvantage is frequently encountered when the combustion chamber is provided with a mating member arranged symmetrically to the combustion chamber centerline. The risk of the fitting member becoming loose is further increased by ON-OFF control of the combustor. If the fitting member comes out of the tunnel of the combustion chamber, the furnace will be out of service for a long time, repair costs will increase, and the heating process will be interrupted, which inevitably results in losses.

According to the invention, the combustion chamber includes a casing forming an axial tunnel and a hollow fitting member supported by the casing, the hollow fitting member being combined with the tunnel and coaxial with the casing axis. The fitting member has an end face perpendicular to the casing axis, and in this configuration, the center line of the fitting member is inclined with respect to the end face, and the fitting member center line and the casing axis form an acute angle. .

ができる。 The combustion chamber of the inventive structure firmly holds the mating member, which is held and wedged to the seat of the casing by gravity and the tilting forces generated during operation of the device. Heat-resistant means for fixing the fitting member disposed in the combustion chamber casing of the present invention can be omitted. Therefore, the combustion chamber fitting member of the present invention is easily replaceable. Therefore, the present invention can extend the life of the combustion chamber, reduce operating costs, and increase production by reducing downtime due to combustion chamber repairs and fitting member replacement.

材料を節約することができる。 In a preferred embodiment, the mating member is positioned within the casing such that the casing centerline intersects the casing axis at a location upstream of said inner end face with respect to the flow of combustion products. This embodiment increases the tilting force that holds the mating member in its seat in the casing, and this force increases the angular force that holds the mating member in its seat, even if the angle formed between the centerline of the mating member and the combustion chamber axis is small. Large enough to hold parts. This allows the dimensions of the combustion chamber to be reduced and the materials necessary to construct the combustion chamber to be saved.

By suitably selecting the ratio between the dimensions of the mating member and the dimensions of the combustion chamber casing, reliability in retaining the mating member within the combustion chamber is improved.

In the figure, P 1 indicates the pressure inside the combustion chamber 1,
P 2 is the pressure inside the machine. These forces acting on the mating member 4 generate a tilting moment due to the asymmetrical nature of the mating member 4. This tilting moment is expressed as M=P×a, where M is the tilting moment, P is a constant force, and a indicates the distance of force P. As shown in FIG.
