Definitions
- the present invention relates to a generation device a stream of hot air.
- the present invention can be used in many installations requiring a current of hot air, such as facilities for monitoring the holding materials or for aerodynamics or validation of wall cooling systems, it will be described more particularly below in the context a test bench for the development of ramjet engines.
- heaters static with a heater, for example a gas burner or an electrical device, and intended for heating a material having a high thermal capacity, such as alumina beads or tubes metallic.
- a heater for example a gas burner or an electrical device
- a material having a high thermal capacity such as alumina beads or tubes metallic.
- document EP-A-0343938 discloses a air conditioning or air conditioning system of a building, which seeks to obtain a draft not polluted and heated.
- this document known provides a first air path from the outside towards the interior of the building and a second air path of inside to outside of the building, independent one of the other. Therefore, this known device is complex.
- the treatments undergone by the circulating air according to these routes are varied and said first route which uses air from the outside environment including subject to heating and humidification.
- the object of the present invention is to remedy these disadvantages. It concerns a generation device hot air likely to supply unclean air at high temperature, and this without limitation of duration.
- the device for generation of a stream of hot air especially for development of ramjet engines, including a source air generating an air current at its outlet, a system heating at least one burner supplied with fluid fuel and a thermal system with heat transfer elements likely to store the thermal energy generated by said heating system and restore this thermal energy to said current air, said thermal system being arranged on a mobile support capable of passing said system thermal of a first position for which it found next to said heating system to a second position for which it is located next to the exit of said air source is remarkable in that the elements heat transfer fluids are made of a material with high specific heat and distributed on said mobile support of so as to continuously renew the heat transfer elements arranged in said air stream and beforehand heated by the burner of said heating system, and in this that said heating system uses, for combustion combustible fluid, air from said air source and not used for the generation of said current hot air.
- the current of hot air generated is not vitiated by said heating system, which makes it possible to obtain hot air having the same purity as the air generated at the outlet of the air source.
- said mobile support is rotatable, which simplifies the device according to the invention.
- said mobile support has the at least partially cylindrical container shape filled with said heat transfer elements.
- said cylindrical container is provided in the upper wall of a first annular opening concentric with the axis of the cylindrical container and in the lower wall of a second annular opening also concentric to the axis of the cylindrical container, said second opening being provided with a wire mesh, and the output of the heating system and the output of the source of air being arranged below said second opening diametrically opposite relative to the axis of the cylindrical container.
- the device according to the invention comprises advantageously a stationary enclosure, said container being movable in said enclosure and outlets of said air source and said heating system being arranged in said enclosure.
- said device comprises insulation means arranged between the container and the enclosure and intended to prevent air circulation between said container and said enclosure, which prevents that of unheated air coming directly from the air source, or possibly stale air from the heating, mixes with the generated hot air current.
- the generated stream of hot air can be exhausted by the nozzle to be transmitted to a user device, like for example a combustion chamber of a ramjet mounted on a test bench, and the air flow from the heating system, possibly flawed, can be evacuated through the exhaust pipe, both drafts that cannot mix together the other.
- said exhaust pipe is provided a controllable internal valve capable of modifying the opening for the exhaust.
- a passage is provided between said container and said enclosure to allow circulation air from the air source outlet to the heater.
- Figure 1 is a schematic sectional view of a device according to the invention.
- Figure 2 is a bottom view of the device of the Figure 1 shown partially cut away.
- Figure 3 is a top view of the device of Figure 1.
- the device 1 according to the invention and shown in the Figures 1 to 3 is intended to generate a draft hot.
- Said device 1 comprises an external enclosure 2 mounted at landline and a mobile system in the form of a cylindrical container 3 movably mounted inside of said enclosure 2.
- said cylindrical container 3 is integral a shaft 4 of axis X-X, rotatably mounted in the upper wall 5 and the lower wall 6 of the enclosure 2 and likely to be rotated, as shown by an arrow E, by a type of drive device known and not shown.
- Said container 3 has a symmetry of revolution around said axis X-X and is provided in its upper wall 7 with a concentric annular opening 8 at the X-X axis and in its bottom wall 9 with an opening annular 10 opposite opening 8.
- Said opening annular 10 is covered with a wire mesh 12.
- the air stream B is likely to flow at through said container 3, in which it can be heated as we will see below, towards the opening annular 8 formed in the upper wall 7 of said container 3, while air A from said air stream B generated by the air source is capable of flowing through a passage 19 formed between the lower walls 6 and 9 of said enclosure 2 and of said container 3 , to supply air to said burners 14 during the combustion of the combustible fluid.
- said container 3 is filled with elements heat transfer fluids 27, for example balls or tubes, only shown in the bottom of the container 3 on the figure 1.
- said heat transfer elements 27 are shown so not very compact in this figure 1.
- said container 3 can be completely filled with such elements heat transfer fluids 27, and this very compactly, the filling being defined according to the results to be obtained, as we will see it below.
- Said heat transfer elements 27 preferably have a high ratio between their surface external and their volume and are preferably made in one material with high specific heat, such as example of zirconium dioxide.
- the device 1 To generate a current of hot air, the device 1 according to the invention operates as follows.
- Said burners 14 heat the heat transfer elements 27 located above them. Combustion gases from said burners 14 flow out of the container 3 and enclosure 2 through openings 8 and 23, as indicated by arrows C, and are evacuated through the exhaust pipe 25.
- the heat transfer elements 27 thus store energy above the outlet 16 of the heating system 13. They restore this stored energy after the rotation of a U-turn of container 3 bringing said heat transfer elements 27 in said air stream B, said air stream B. Thus, said air stream B is heated.
- the heat distribution in the heated air stream F is made homogeneous by the passage of said air stream F in said mixing system 22 so that, the outlet of said nozzle 21, a stream of heated air G of homogeneously.
- the air generated by the air source can no longer flow directly through opening 23, as shown by arrows D, the importance of this dependent flow in particular the aerodynamic resistance of the elements heat transfer fluids 27 placed in the container 3.
- the distribution of the flow out of the container 3, respectively at through the exhaust pipe 25 and the nozzle 21, depends especially the importance of their sections respective. This distribution can therefore be adjusted by modifying the section of the exhaust pipe 25 by via the controllable valve 26.
- insulation is established between the container 3 and enclosure 2, for example using labyrinth seals 28 arranged between their vertical walls and a wall mobile not shown arranged between their upper walls, which prevents air circulation between enclosure 2 and container 3 so as to avoid mix with said stream of hot air, on the one hand air not heated directly from the air source, and other part of the possibly stale air coming from the heating 13.
- the nozzle 21 present in its middle part 29 a decrease in diameter so as to allow forced air evacuation.
- Said current of hot air G available at the outlet of said nozzle 21 can be used, for example, for checking holding materials or for aerodynamic tests or validation of wall cooling systems.
- said stream of hot air is used for the development of ramjet engines, for which it has the appropriate characteristics like recalled previously, the device 1 according to the invention being associated for this purpose with the test bench used for this focus.
