Gas burner provided with a plurality of concentric circular flame crowns, with a burner body apt to be mounted on the surface of a cooking plate, a burner body apt to be mounted on the surface of a cooking plate and provided with a first chamber for the diffusion of the air/gas mixture, and whose top is closed by a first cover, a second outer annular burner surrounding said central burner, a first gas inlet in communication with said body, a first gas injector able of injecting a gas flow into a respective Venturi pipe to said first central burner, a second gas inlet in communication with said body, wherein said second annular burner is provided with two separate diffusion chambers, and whose top is closed by a second cover, wherein said second gas inlet is in communication with said two separate chambers which are not in communication to each other, two distinct injectors connected with said second gas inlet and placed on the same end position of said second gas inlet, two respective horizontally oriented Venturi pipes, each of which being able of supplying with an air/gas mixture a respective of said two diffusion chambers; said first gas injector and the respective Venturi pipe for the central burner are horizontally oriented, and preferably they are positioned between the two Venturi pipes dedicated to said two diffusion chambers. Said two horizontally oriented Venturi pipes for the outer annular burner and the relevant gas injectors are angled to each other, and this angle is over 70°. Preferably the Venturi pipes for the annular burner admit into respective curved chambers provided with respective vertical gas passages, extended for the whole length of said curved chamber, connecting them to respective diffusion chambers. |
