DOUBLE BURNER FOR GAS HEATING STOVES WITH MULTIPLE FLAME CROWNS Russian patent published in 2012 - IPC F23D14/06 F23D14/64 

FIELD: power industry.

SUBSTANCE: double burner for gas heating stoves with multiple concentric flame crowns includes head (T) with multiple concentric flame crowns and circular bucket-shaped housing (1) that contains cross piece (2) with nozzles in upper section and two different non-interconnected gas inlet tubes (3 and 4) in lower section; at that, each of those has the possibility of selective and corresponding feed of nozzle (5) connected to central flame crown (FC) and group of nozzles (6) connected to external flame crowns (FE). Group of nozzles (6) consists at least of three distant nozzles (6) which feed the corresponding Venturi mixing chambers (6a) having inclined axes, and nozzle (5) feeds the corresponding radial Venturi mixing chamber (5a) having a vertical axis. Burner includes diverting partition (100) arranged before outlet opening of each axial Venturi mixing chamber (6a), which causes diversion of mixture transversely in two directions and downwards till it passes through opposite pair of openings (101) arranged on both sides of diverting partition (100), through which the above mixture reaches passages (11) which feed openings (103) from which external flames (FE) are discharged. Head (T) is formed with lower disc (7) and upper disc (8), which have such shape that ensures their full combination, and that the above diverting partitions (100) are obtained by simultaneous formation with upper disc (8) of head (T), which has the above openings (101). Circular passages (11) are made on upper side of disc (8) and partially contain circular cover plate (102) having a row of openings (103) from which external flames (FE) are discharged.

EFFECT: high efficiency, compact height and uniform external flame as to length and colour.
