A catalytic igniter for methane flames has been developed which overcomes the inhibition caused by preoxidation reactions on catalytic surfaces. The design of the igniter mimics the dual activity principle of two-phase igniters for certain types of fuel, but achieving this function within a single phase by utilizing specific structures of filaments of fine platinum wires. These igniters are capable of delivering thousands of ignitions. Two unexpected effects were encountered: a gradual complete deactivation of platinum wire for methane ignition by exposure to air at any temperature < 800 degrees C; surface migration of platinum at standby from filament zones > 800 degrees C to areas < 800 degrees C.
