A catalytic ignition system includes a gas fuel supply and a catalytic igniter that is in fluid communication with the gas fuel supply. The catalytic igniter comprises a metallic shell, a catalyst disposed within the metallic shell and a fuel tube that is oriented so as to direct a flow of gas fuel from the gas fuel supply across the catalyst and towards a downstream end of the metallic shell. |

A catalytic fuel igniter is compatible with internal combustion engines and other chemical fuel operated systems. The catalytic fuel igniter does not require electrical components typically required for such systems, thus reducing complexity. The catalytic fuel igniter includes a catalyst in a controlled environment which ignites the fuel and air at the proper time for engine operation. In one embodiment the fuel is a hydrogen fuel and the catalytic fuel igniter is a hydrogen fuel igniter. |

PURPOSE: To leave an igniter at a sufficiently high temperature for continuous ignition of fuel coming without requiring power and to guarantee against a frame-out of a combustion chamber, by igniting atomized fuel entering the combustion chamber of a gas turbine by contacting it to thermal surface igniter when entering the combustion chamber. CONSTITUTION: Air passages 3, 4 and whirlers 5, 6 respectively whirl air flowing through flow passages 3, 4, thus atomizing fuel coming out of a fuel passage 2 through a nozzle chip 7, and generating shearing force required for mixing it. In an operation, the atomized fuel contacts with a hot surface of an igniter 1 due to the air flowing through flow passages 3, 4, and therefore, the fuel is ignited on a surface toward a combustion chamber. During start-up of a gas turbine engine, the igniter 1, prior to introduction of the fuel, is heated to a temperature higher than a minimum temperature required for the ignition under a given air flow condition, and thus speedy start of the ignition is ensured. After the start of the ignition, power to the igniter 1 is controlled. |

An assembly for the catalytic ignition of atomized fuel for combustion within the combustion chamber of a turbine engine places the catalytic fuel igniter in a position to receive the atomized fuel upon entry into the combustion chamber. The igniter is heated to operating temperature so that at least a portion of the atomized fuel enters the combustion chamber in an ignited state. |

A method and apparatus for the ignition of a hydrocarbon gas stream utilizing a hydrogen pre-ignition arrangement. A small volume of hydrogen gas is mixed with air and directed past a platinum containing catalyst, e.g., activated with aluminum and in mesh form to heat the catalyst. A flame is produced and extends away from the catalyst and is directed from the catalyst so that it intersects a hydrocarbon gas stream and ignites the hydrocarbon gas stream at room temperature. |

An improved catalytic pilot ignition system which utilizes a short-circuited, air-starved, electrochemical cell or battery comprising a metal electrode and an inert electrode, such as zinc and carbon electrodes, or metal-air battery such as a zinc-air battery, which will produce a small but sufficient flow of pure hydrogen gas. When such a battery is short-circuited, the current often rises to a level above that which can be supplied with atmospheric air. When this happens, hydrogen is evolved. The evolution of hydrogen ceases immediately when the short-circuited current is interrupted. If a zinc-air battery is operated without access to the air, any current drawn from the cell will produce hydrogen at the air electrode.

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. |
