<p>A gas cooker or cooking hob includes at least one burner with two concentric flame crowns, an inner crown (1) and an outer annular crown (2), with a first delivery tube (9) supplying the outer crown (2) and a second delivery tube (10) supplying the inner crown (1), the gas flow in each of said delivery tubes (9, 10) being adjusted in an independent manner through a relevant tap. This arrangement provides complete freedom of adjustment of the flames, since each crown (1, 2) of the burner can be adjusted individually from a minimum to a maximum, whereby both the power and the flame distribution of the burner can be changed at will. <IMAGE></p> |
