BURNER DEVICE Russian patent published in 2003 - IPC

FIELD: power engineering, particularly, burner devices, possibly used in automobile making industry branch. SUBSTANCE: on lateral surface of air feed nozzle there are at least two rows of the same number of symmetrically arranged in longitudinal direction radial openings spaced one from another along height of nozzle. Each opening of upper row is arranged on line equally spaced from two nearest openings of lower row. Device includes in addition vortex stream generator arranged between air feeding nozzle and capillary structure of evaporation member having axially symmetrical surface. Vortex stream generator has lengthwise openings shifted relative to openings of air feeding nozzle by 1/2 of angle formed by two adjacent openings of said nozzle. Vortex stream generator has surface zone with curvature radius between openings less than distance from nozzle axis until nearest surface element of vortex stream generator. Low base of vortex stream generator adjoins fluid-tightly or with gap to capillary structure of evaporation member arranged on end surface of burner chamber; its upper base adjoins to flame stabilizer. Between openings on surface of vortex stream generator in zone of air jet striking there is local longitudinal protrusion whose length is equal to height of openings in air feeding nozzle. EFFECT: enhanced intensity of burning, prevention of coking in capillary structure of evaporation member, enhanced reliability and efficiency of burner device. 4 dwg
