RADIOELECTRONIC AND COMPUTER SYSTEMS

The most common way to increase power and reduce fuel consumption by modern power plants is contact cooling of a gas or air flow by water injection. A promising development of this direction is to use aerothermopressor technologies. The use of heat air, which is compressed by the power plant compressors, accelerates the flow to a speed close to the sound one and almost instantaneous evaporation of injected water (the effect of thermo-gas-dynamic compression). It is important to determine the rational parameters of the organization of thermophysical and hydrodynamic processes when developing such technologies. In this case, one should be taken into account the appropriate development of the flow path design and a special software product. It is necessary to use methods and means to determine the optimal operating parameters of the power plant heat recovery systems. This paper presents a block diagram and an algorithm of a rational methodology for designing an aerothermopressor, which makes it possible to accurately determine the efficiency of using an aerothermopressor as part of a power plant (based on a gas turbine engine) for cooling cycle air, considering the peculiarities of operating modes in the flow path, as well as under various climatic operating conditions. The algorithm of a rational methodology for designing aerothermopressor technologies allows calculating the characteristics of equipment, systems, and circuit design solutions when used as part of a power plant: an electric generator; heat-using refrigerating machines (ejector refrigerating machines, absorption refrigerating machines); turbine generator or steam generator as part of a trigeneration unit or as part of a turbo-compound unit (power plants of marine vessels); recovery boiler of one or two pressures. Modeling the aerothermopressor-cooling system operation makes it possible to reveal the effectiveness of using such a system as part of a power plant and compare it with traditional methods of cooling and humidifying cycle air.
