ABSTRACT:
A method is presented for stabilizing the flame on the tips of burner internals in a process for preparing synthesis gas by partial oxidation of a gaseous hydrocarbon-containing fuel. The method comprises supplying a gaseous hydrocarbon-containing fuel, a moderator gas and an oxidizer through a burner to a reactor, and adjusting the mass flow of the moderator gas such that the moderator gas concentration does not exceed a predetermined limit. The process conditions are effected such that the flame contacts the burner internal tips. In case of flame-lifting from the burner internal tips, the velocities and mass flows of the fuel and/or oxidizer and/or moderator gas are re-adjusted in such a manner that the flame is restabilized on the burner internal tips.
