The burner has a upward opened lower gas distribution chamber (13) formed in a burner lower part (1), where a burner upper part (2) is loosely attached at the burner lower part and partially closes the lower gas distribution chamber. A circular upper gas distribution chamber (14) is formed in a burner ring, and a gas discharge opening connects the lower gas distribution chamber with the upper gas distribution chamber. The burner lower part comprises a radial secondary air passage for supplying secondary air to an inner area of the burner. |
