A radiation gas burner comprises a burner stone having an axis and a front surface over which a flame is distributed and which is heated by the flame so as to radiate heat, the burner stone being ring-shaped, an outlet pipe arranged radially inwardly of the burner stone and having an inner cylindrical space with an axially rear inlet and an axially front outlet, means for supplying fuel into the rear inlet of the inner cylindrical space of the outlet pipe, first passage means extending from the front surface of the burner stone and through the burner stone rearwardly, second passage means through which a primary air is supplied into the rear inlet of the inner cylindrical space of the outlet pipe to form a fuel-gas mixture which is supplied through the outlet pipe and exits through the front outlet, and third passage means through which secondary air passes through the burner and exits at the front surface, the first passage means for recirculating combustion products through the burner stone communicating with at least one of the second passage means and the third passage means so as to ballast at least one of the primary air and the secondary air with the combustion products which have passed through the burner stone.
