Zaytsev O. The intensification of processes of rotaries gas currents interaction in energy saving technologies of industrial power systems

The technical feasibility of creating of decentralized development of heat system is theoretically justified on the basis of interreacting rotaries streams, in devices where the aerodynamic circumstances are changed that allows to increase productivity of fuel and energy resources essentially. It is detected that the reason of inhibition of pulsations PVC is its transition from gyration as solid bodies to gyration under the law of a free vortex attending by split of a vortex core into some kerns precessing with smaller intensity. The analytical dependences for definition of perturbing force induced PVC in a rotaries gas current, velocity in a twisted stream from a precession of a vortex core, time, coefficient of viscosity both rotation frequency of a stream and dependence of amount of twist of a gas current on an oscillation frequency PVC, gas flow rate and design data in stability conditions of a twisted gas current are obtained. The theoretical models at different views of interaction of rotariesgas jets are designed. The expedients of intensification of heat transfer in combustors, localization of a thermal torch are offered at welding in protective gas, plasma-electric arc cutting, construction of the device for an ejection of gases from a draft stack, receiver of a dust, washing column, kettle for clearing of air, battery cyclone collector. The technological analysis has shown, that at introduction of offered measures the economies will make 4,1 м3 of gas perf kW of used power of the boiler, and payback time compounds 5,5 years.
