IMPROVED GAS BURNER Russian patent published in 2018 - IPC F23D14/06 

FIELD: power engineering.

SUBSTANCE: invention refers to power engineering. Improved gas burner (2) comprises injector holder (4) provided with means (20) for mounting it in the top sheet of the metal of the hob and comprising cup-shaped central cavity (10), to the base of which central injector (14) is applied, and further comprises two lateral cup-shaped cavities (12, 12'), to the base of which two lateral injectors (16, 18) are applied, said cup-shaped cavities (10, 12, 12') are closed on the base and sides and open from the top, at least one gas inlet (6) provided in said injector holder (4) and communicating with said injectors (14, 16, 18), flame divider (24) located on injector holder (4) and defining central distribution chamber (48), with a substantially cylindrical side wall with apertures (64) for producing a central flame ring (80) and an annular distribution chamber (52) which is separated from said central distribution chamber (48) by means an annular cavity (34) and has its outer side wall with apertures (66) for producing ring of outwardly directed flames (84), circular closing cover (74) for said central distribution chamber (48) and annular closure cover (76) for said annular distribution chamber (52), at least one connecting passage between the space, surrounding burner (44) and said annular cavity (34) of flame divider (24), characterized in that annular chamber (52) of flame divider (24) has two lateral conduits (50), which are located along their axes almost vertically, their lower ends face indicated lateral injectors (16, 18), wherein said lower ends (60) are located higher than upper edge (62) of injector holder (4, 88), have an upper end portion that projects and exits base (53) of annular distribution chamber (52), are designed in such a way as to produce a practically vertical venturi effect, so that the outflow of gas and air and the incoming gas to annular distribution chamber (52) is already substantially mixed.

EFFECT: invention makes it possible to create a burner with a simple, fast and inexpensive assembly.
