Abstract: In a pressure wave machine with integrated combustion, which consists essentially of a rotor (1) which rotates between two side parts (4), (5) and has cells (2) in which an ignition and combustion process takes place repetitively, cooling air conduits (7) are arranged in the casing and passages (3) are arranged in the rotor (1) below and above the cells (2), viewed in the radial direction. The rotor (1) can be additionally surrounded at its inner periphery and outer periphery by at least one sheet-metal guide (8) in order to form further cooling passages (6), the internal space of the pressure wave machine casing being connected to the low-pressure outlet. For cooling the rotor of the pressure wave machine, a small part of the entering air is branched off before the admixture of the fuel, is led through the casing by cooling air conduits (7) and is subsequently guided through the passages (3), the cooling air itself then being subjected to its own pressure wave process.

Abstract: The use of a pressure wave machine as energy exchanger (C) in a gas turbine plant makes it possible, owing to the self-cooling cellular wheel (22), to employ substantially higher temperatures. However, in order to be able to make full use of this advantage, steam cooling (13) is applied for the low-pressure gas outlet ducts (35, 37), while in addition means are provided for utilizing the heated cooling steam in a part of the gas turbine, for example in the combustion chamber (D) or in the turbine (B).

Abstract: A dynamic pressure machine with integrated combustion has a cellular wheel containing a number of cells, in which a continuously recurring ignition and combustion process takes place. Neither energy supply from the outside nor a control action should be required to maintain this continuously recurring process. Means are provided for the automatic ignition and combustion of the entering fresh air-fuel mixture, in particular: at least one hot gas pocket disposed on the wall of the cell; a catalytic coating of the cell wall; and, a hot spot in the cell.

Abstract: A pressure wave machine with integrated combustion has a cellular wheel (10) containing a number of cells (16) in which an always recurring ignition and combustion process takes place. To maintain this always recurring process, neither a supply of ignition energy from the outside nor a control intervention should be necessary. Hot-gas channels (18) are provided, by means of which hot gas is taken from one cell (16), in which the combustion step belonging to a cycle has been completed, and recycled to a cell (16) which contains the fuel/air mixture which is to be ignited.

Abstract: In a rotor of a pressure wave machine, rotor cells (2) are evenly distributed at its periphery, these rotor cells being intended to accept two gaseous media during operation for the purpose of compressing the first by means of pressure waves of the second medium. The rotor cells are arranged in such a way that they extend in a plane normal to the axis of rotation of the rotor (1).

Abstract: This pressure wave machine has a cell wheel (2) with a longitudinal axis (3) which is supported in a casing by means of a bearing. One end face (4) of the cell wheel (2) interacts with a hot gas guidance casing (6) and the other (5) interacts with a gas guidance casing (8) by means of a radially directed sealing gap (7, 9) in each case. The invention is intended to provide a pressure wave machine (1) whose performance during a cold start is the same as that after the operating temperature has been reached. This is achieved in that the radially directed sealing gaps (7, 9) have at least one gap extensions (20, 21) inclined to the longitudinal axis and that flanks (22, 23, 28, 29) of this gap extension are located on the generated surfaces of cones which have a common apex on the longitudinal axis (3).
