A multi-crown gas burner comprising an injector holder module, attachable to a cooking hob, and a flame-spreader module positioned above said injector holder module, said flame-spreader module comprising a circular internal portion which is separated from an external annular portion by a substantially annular cavity, said injector holder module comprises:
at least one first venturi duct substantially horizontal to which at least one first injector faces, said at least one first venturi duct being in fluid communication with a corresponding first chamber which is in fluidic communication with a first set of doors provided in said external annular portion, so as to generate at least one first crown of main flames,
a second substantially horizontal venturi duct to which a second injector faces, said second venturi duct being in fluid communication with a zone communicating fluidly with at least one passage provided in said circular internal portion for the generation of at least one simmering flame,
said at least one first chamber, which is fed by said at least one first venturi duct, communicates fluidly with a second set of doors provided in said circular internal portion of the flame-spreader module, so as to generate a second crown of main flames.
