Definitions
- the invention relates to a method for permanently achieving high gas temperatures and minimizing heat losses.
- Cooling gas turbines is a technical challenge that is particularly critical in aviation. Complex cooling methods such as impingement and film cooling, transpiration cooling, effusion cooling etc. are used in modern gas turbines, see for example patent specifications DE000069911600T2, EP000003179041 A1, EP000001043480A2, EP000001149983A2, EP000003199759A1,
- DE000002905206A1 describes a system for thermal water splitting in which concentrated sunlight is used to generate the reaction temperature above 1100° C. and a high-temperature reaction vessel is formed by electromagnetic fields.
- the disadvantage of this system is that such a reaction vessel can hardly be realized in practice.
- a method for the rotational confinement of plasma disclosed in DE102009052623A1 is closest to the patented invention.
- the method relates to hot plasma maintenance but is not concerned with achieving high temperatures of non-ionized gases.
- the disadvantage of this method is that it requires a lot of energy because the plasma can only exist if there is a constant supply of energy.
- the invention is based on the object of providing a method which ensures that hot gases are separated from structural walls and, as a result, high gas temperatures can be achieved in the work area.
- the object is achieved with a method which is characterized in that a hot gas or a gas mixture is kept in a chamber under constant rotation, the rotating gas due to the action of centrifugal force separating colder and therefore heavier and hotter and thus experiences lighter gas layers and thus a displacement of the hotter (lighter) gas in the center of rotation of the chamber and the colder (heavier) gas in the direction of the chamber wall takes place.
- the chamber walls are effectively separated from the hot gas masses in the center by a heat-insulating, colder gas layer, thus preventing the chamber walls from overheating.
- the walls of the chamber do not come into direct contact with hot gas, thereby advantageously reducing the contamination of reaction products by material from the walls.
- FIG. 1 shows an embodiment 1 with a rotating tube (1) with open ends (2), a gas (3) being introduced at one end of the tube and being heated in a manner known per se.
- the gas (3) (or the reaction products) flows out at the other end.
- the gas is kept at a high temperature according to the invention and the tube walls remain at a lower temperature thanks to the heat-insulating gas layer.
- Fig. 2 is shown an example 2 of the invention where the gas (3) is made to rotate in a non-rotating tube (4) by a bladed impeller or fan (5).
- the gas is heated as in Example 1 and separated from colder walls according to the invention.
- FIG. 3 shows an example 3 for a closed container (6), the interior of the container (6) being under normal, negative or positive pressure.
- a gas (3) (or gaseous reagents) is kept at a high temperature in the container (6) according to embodiment 1 or 2, i.e. in a rotating tube (1) or in a non-rotating tube (4), according to the invention for intended work processes.
- the centrifugal force acts only in the radial direction, which means that the thermal insulation according to the invention does not function in the axial direction.
- the tube length can be made significantly larger than the tube diameter (e.g. in the ratio 10 to 1). This disadvantage cannot arise at all if a chamber is annular, such as a torus or two tubes connected at both ends, so that there are no free ends of the hot gas vortex.
- the embodiment 4 shows possible designs (4.1, 4.2, 4.3).
- the chamber can be directed horizontally or with an inclination, see Fig. 5. If the outlet end of the chamber is directed downwards (5.1), a separation of fixed Reaction products facilitated by the action of Earth's gravity. On the other hand, with an orientation upwards (5.2), light gaseous products can escape better.
- the proposed method was tested and successfully confirmed by the inventor in a series of experiments on a test facility. By using this method, heat losses and thus energy requirements can be significantly reduced. Higher efficiencies can be achieved.
