摘要	PURPOSE:To perform a positive ignition within a short period of time by a method wherein an ignition catalyst is contacted with one end of a main catalyst layer and a downstream side of a supporting member so as to close a flow passage of fuel gas. CONSTITUTION:Fuel gas (a) is passed through a main catalyst layer 4 and passed around an ignition catalyst layer 5. A volume of gas per unit area of ignition catalyst layer 5 is much higher than that of gas passing through a unit area of the main catalyst layer 4. Thus, the ignition catalyst layer 5 is heated up to 150-350 deg.C and reached to such a temperature as enabling an ignition rapidly. The fuel gas shows a rapid ignition at the ignition catalyst layer 5, an increased temperature of the ignition catalyst layer 5 is transmitted through the supporting member 3 or transmitted to the main catalyst layer 4 directly, resulting in that the main catalyst layer 4 is heated up 150-350 deg.C and reached to such a temperature as enabling combustion to be performed. The fuel gas is started to ignite more than 90% at the main catalyst layer 4. With this arrangement, the ignition is easily initiated.
