Abstract (en)
[origin: EP1531304A2] The gas burner for a cooking hob includes a circular body (2) with at least one peripheral flame crown (3,4) and one central flame crown (5), each of them with its respective annular chamber (6,7) for distributing the mixture (M), various horizontal venturi ducts (9b) extending in a radial direction, and a radial channel (13a) formed below the surface of the crowns (3,4,5), its length (L) being longer than the radius (R) of the area of the central chamber (7), whereby the circulation path (L) of said flow portion (Fc) is prolonged for the purpose of the complete homogenizing the mixture. Said radial branch channels (13a) extend from the peripheral end (16) of each radial venturi duct (9b) in a radial direction upstream as far as an opening (17) in the bottom of the central chamber (7), and they are formed by means of an intermediate plate (13) between the body (2) of the flame crowns and said radial venturi ducts (9b).
