Adjacent first flame channels (13) are separated one from another with second flame channel (17) positioned between them so, that first flame channels (13) and second flame channels (17) are positioned on the tooth ring at an equal distance one from another. The burner is equipped with a vertical mini-tube of Venturi to perform primary aeration over working surface of a stove. Periphery step (15) is made below the level of first flame channels (13) and has smooth surface. Periphery step (15) at least partly is crossed with radial grooves (16) connected with corresponding first flame channels (13) of tooth ring (12).
