Abstract: A multi-crown gas burner with an injector holder module is attachable to a cooking hob and includes a flame-spreader module, positioned above the injector holder module, which includes a circular internal portion separated from an external annular portion by a substantially annular cavity. The injector holder module includes: at least one first venturi duct substantially horizontal to which at least one first injector faces, the at least one first venturi duct in fluid communication with a corresponding first chamber in fluid 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, the second venturi duct is in fluid communication with a zone communicating fluidly with at least one passage provided in said circular internal portion for generating at least one simmering flame.
