果を招いていた。[Prior Art] Conventionally, when a new engine is developed, the exhaust system equipment associated therewith is also evaluated. For example, a manifold evaluation test is carried out by mounting the engine on the engine after the development of the engine is completed. Therefore, the manifold evaluation test cannot be performed until after the engine is completed, resulting in an unfavorable result that the development period of the engine is significantly extended.
そこで、本出願人は実願昭63−5509（耐熱管状部材の試

改善された。Therefore, the present applicant previously proposed Japanese Utility Model Application No. 63-5509 (test apparatus for heat-resistant tubular members). According to the above-mentioned device, the delay of heating and cooling due to the storage heat of the combustion chamber was improved within the range of measurement error in the measurement of the long test cycle of heating and cooling cycle of 10 minutes or more.

の形状に問題が残されているためである。[Problems to be solved by the invention] However, the delay in temperature rise of the surface temperature in a short test cycle of 10 minutes or less has not been improved yet. This is the intermediate member 13
This is because there is still a problem with the shape of.

熱時の熱変形のために該中間部材13中の耐火材18に亀裂
が生じ該中間部材13が破損するという問題があった。That is, as shown in FIG. 2, the intermediate member 13 is like a cylinder head, but its internal structure is filled with the refractory material 18 and the flame passage 19 is formed by hollowing out the refractory material 18. However, in such a structure, the intermediate member
Since the heat capacity of 13 increases, the intermediate member 13
Heat is used to warm the air, and the cooling air is kept warm by the heat of the intermediate member 13 that has stored heat during cooling, making it difficult to reproduce the heating and cooling conditions in a short time. Further, there is a problem in that the refractory material 18 in the intermediate member 13 is cracked due to thermal deformation during heating and the intermediate member 13 is damaged.
本考案の目的は、上述せる欠点を解消し、目的とする加

A burner inserted into the combustion chamber connected to the air passage and the fuel supply passage,
A test apparatus for a heat-resistant tubular member having an exhaust pressure-enhancing air passage opening to a chamber wall of a burner section of a combustion chamber, wherein an outer wall of the intermediate member is formed of a steel plate, and an internal flame passage is formed of a heat-resistant metal tube. It is characterized in that a cooling fluid having a cooling ability is caused to flow through a cavity formed by the outer wall and the heat-resistant metal tube.

Further, the cooling medium for the cavity formed by the outer wall and the heat-resistant metal tube improves the heat resistance and heat capacity of the heat-resistant metal member, and also improves the temperature responsiveness during heating and cooling.

FIG. 1 is a sectional view of an apparatus for testing a heat-resistant tubular member according to the present invention. The intermediate member 13 is joined to the outer wall 22 for fixing the combustion chamber 1 and a fastening member with a gasket interposed therebetween to prevent gas leakage, and a flame passage 19 is formed between the combustion chamber 1 and the tubular heat-resistant member 16. By connecting with the heat-resistant metal pipe 17, the high-temperature gas generated by heating in the combustion chamber 1 by liquid, solid or gaseous fuel such as LPG is introduced into the tubular heat-resistant member 6. Since a high temperature gas passes through the combustion chamber 1 and the refractory metal pipe 17, a ceramic pipe 12 is inserted in the combustion chamber 1 and
In addition, a fluid having a cooling capacity is circulated around the heat-resistant metal tube 17 so that it has heat resistance and the heat capacity is reduced to improve the temperature responsiveness during heating and cooling.

量が小さくなったためである。FIG. 3 shows a conventional test apparatus and the test apparatus of the present invention, in which a temperature sensor 14 is attached to the outer surface of the heat-resistant tubular member 6, and the heat-resistant tubular member 6 is heated and cooled in a short cycle of 2.5 minutes of heating and 2.5 minutes of cooling. This is a comparison of the temperature rising / lowering state when the temperature is raised and lowered when the engine is actually attached to the engine. In the figure, (a) shows a conventional state, (b) shows the present invention, and (c) shows an ascending / descending state attached to an actual engine. From the figure, in the temperature rising / falling state (a) by the conventional heating test device, the surface temperature in the initial stage of heating is high, and it takes a long time to reach the set temperature, which is greatly separated from the surface temperature condition when it is installed in an actual engine. On the other hand, the temperature raising / lowering state (b) by the heating test apparatus of the present invention matches the temperature raising / lowering state (c) actually attached to the engine very well. This is because the flame passage 19 of the present invention is formed only by the heat-resistant metal tube 17,
Moreover, since the surroundings are cooled by the fluid, the heat capacity of the intermediate member 13 is reduced.
また、このために熱変形量が小さくなり耐久性が大幅に
向上した。In addition, because of this, the amount of thermal deformation is reduced and durability is greatly improved.

有するものである。[Effects of the Invention] As is clear from the above description, the heat-resistant tubular member testing device of the present invention can reduce the heat load applied to the intermediate member, so that the test temperature can be greatly controlled in a very short cycle. It has an excellent effect that it is improved and the durability is increased.
