HIGH-CAPACITY DOUBLE BURNER FOR GAS STOVES, WITH MULTIPLE CONCENTRIC FLAME CROWNS Russian patent published in 2010 - IPC F23D14/06 

FIELD: power industry.

SUBSTANCE: double burner for gas stoves with multiple concentric flame crowns includes head (T) formed with lower plate (7) and upper plate (8) and having multiple flame crowns and circular bucket-type housing (1) containing the crosspiece (2) holding the nozzle and two separate non-connected tubes (3 and 4) for gas supply, each of which is intended for selective and appropriate power of nozzle (5) connected to central flame crown (FC), and groups of nozzles (6) related to external flame crown (FE). Group of nozzles (6) consists at least of three nozzles (6) located at equal intervals and feeding the appropriate mixing Venturi chambers (6a) with inclined axis, below which on lower plate (7) there located is reflecting partition (10) having V-shape and providing the separation of gas-air mixture flow supplied from mixing chambers (6a) to channel (11) feeding external concentric flame crowns (FE); at that, nozzle (5) feeds the appropriate mixing chamber (5a) with vertical axis ended in annular compartment closed on the lateral side with tooth crown (12) of central flame (FC) and closed from above with round cover (14); at that, lower plate (7) is equipped with lower rows of radiant partitions (15) providing self-alignment relative to housing (1) holding the nozzle and ensuring enough introduction of initial air (A) obtained from above from plate (P) surface.

EFFECT: invention allows increasing the burner capacity at its compact height.
