FIELD: mechanical engineering. ^ SUBSTANCE: method and device can be also used in chemical industry, power engineering. Direction and intensity of working medium flow is preset according to the method by form of rotor and its cellular structure being permeable at different directions. Catalytic material is used as cellular material; moreover power and mass exchange processes and chemical interaction take place inside the body of rotor including its developed surface. Rotor-type power-transforming device has at least one rotor mounted onto shaft for rotation, working medium supply and removal collectors. Rotor can have any geometric shape, for example, disc, cone, truncated cone or sphere being permeable at different directions of high-porous cellular material to form channels inside body of rotor for letting working medium flow. Working medium and heat removal collector is placed along periphery of rotor. Permeable rotor is made of material having non-uniform permeability and is provided with heat-exchange surface. Heat-exchange surface is disposed at one side of rotor which side is opposite to one-directed flow of working medium or it can be placed inside rotor when flows of working medium are oriented at different directions. As a cellular material the catalytic material or ceramic either metal carrier onto surface of which carrier the catalyst is applied. As a catalyst at least one noble metal and/or metal oxide is applied. Metal can be chosen from the group containing IV period transition metals. Direction and intensity of working medium flow can be adjusted according to the method as well as mass- heat-exchange processes can be intensified. Method also allows increasing heat output from unit of area of heat-exchange surface. ^ EFFECT: improved efficiency of operation. ^ 8 cl, 3 dwg |
