<p>The invention relates to heat power engineering. The inventive method consists in transferring heat in a cooler and a regenerator to a section of a slow-moving working medium from the section of the same working medium, which moves at high speed and the static temperature of which is lower than the temperature of the low-moving section of the working medium. Heat transfer is due to the fact that the working medium flowing near the highly rough walls of the channels of the cooler and regenerator, thorough which a gas flow travels at a high speed, has a stagnation temperature substantially greater that the stagnation temperature of the slow-moving section. The use of the inventive method in a closed gas turbine unit makes it possible to entirely regenerate equilibrium heat and to eject a non-equilibrium part of heat to the environment independently of the stagnation temperature of a working medium at the section where said heat has been taken, wherein the temperature of the working medium can be substantially lower than the environmental temperature. In the inventive unit for carrying out said method, a turbine output is connected to a heater input, a heater output and a compressor input are connected through a low-speed input and a regenerator output, respectively, a compressor output is connected, through a heat-insulated nozzle and a cooler, to a generator high-speed input and a high-speed output of the regenerator is connected to the turbine input via a heat-insulated diffuser.</p> |
