Zusammenfassung:A premix gas burner comprises a main body, a porous wall, a distribution chamber delimited by the main body and by the porous wall, and an entrance in the main body for introducing a premix of combustible gas and air into the distribution chamber. The main body comprises a cylindrical shape. The porous wall comprises a first porous wall segment and a second porous wall segment. The first porous wall segment and the second porous wall segment both comprise pores for the premix gas to flow from the distribution chamber through the pores, for combustion of the premix gas outside the distribution chamber. The first porous wall segment comprises or consists out of a shaped segment. The shaped segment is directed to the inside of the distribution chamber, such that when the burner is in use premix gas flows from the distribution chamber through the pores of the shaped segment to the inside of the shaped segment. The second porous wall segment comprises an annular porous wall segment. The annular porous wall segment is provided at the base of the shaped segment. The base of the shaped element is provided at the side of the shaped element opposite to the location of the entrance in the main body.
