Abstracts:

The possibilities of a new efficient method of control structures and vortex or swirling flow. It can influence the structure and twist any swirling flows for a more complete combustion of fuel in burners and flares to suppress the formation of toxic substances during combustion. Showing the experimental data on the distributions in the vortex at the exit of the burner ring zones of strength and weakness of the turbulent exchange in swirling flows, useful in the formation of burners. The comparison of the new method of controlling the twist swirl flows obtained in different registers swirling air, which is used for vortex burners. We developed this method of influencing the swirling flow is directed radially blowing jet system in the swirling flow (RBJ). The Power of Influence RBJ by twisting swirling flow and the structure of the swirling flow is in its features all the known methods of control currents swirling at their formation by varying the geometric relationships of structural elements of devices for swirling air. This opens up new opportunities to create burners clean highly economical flaring energy fuels. Proposed and investigated a new method of controlling vortex (RBJ) - the radial direction of the blowing jets of air or any gas through the wall of the cylindrical channel burner allows for enhanced separation of the swirling flow in the areas of strength and weakness of the turbulent exchange and the size of these zones. This is a useful and effective mechanism for creating a burning flame zones with different atmosphere and temperature in the implementation of staged combustion of fuels in non-stoichiometric atmosphere.
