METHOD OF LIQUID FUEL SPRAYING WITH CENTRIFUGAL ATOMISER (VERSIONS), CENTRIFUGAL ATOMISER (VERSIONS), AND LIQUID-FUEL BURNER

摘要

FIELD: power industry.;SUBSTANCE: liquid fuel spraying method with centrifugal atomiser involves its passage through nozzle with pre-swirling of flow in swirl chamber by supplying to it of fuel flows via tangentially located channels in the chamber walls; at that, additional dynamic acceleration is provided when fuel flows pass via tangentially located channels; for that purpose the latter have variable cross section from larger to smaller one in the direction to inlet of vortex chamber, swirling of fuel flow is performed at least in two stages; for that purpose, fuel flow swirling is performed in series in two concentrically located swirl chambers, starting from external one; for that purpose to each of them the fuel is supplied via tangentially located channels; at that, constriction of tangentially located channels is made either before external swirl chamber or before central one, or before both swirl chambers, thus creating double dynamic fuel acceleration.;EFFECT: invention allows increasing liquid fuel combustion efficiency owing to improving its dispersion.;18 cl, 7 dwg
