Abstract:
Disclosed is a hydrogen igniter for igniting hydrogen contained in a gaseous medium, said hydrogen igniter comprising a housing with openings for the supply and discharge of a gaseous medium, and a filler in the form of bismuth oxide and/or lead oxide, disposed inside the housing. Also disclosed are a system for purifying a gaseous medium of hydrogen having such a hydrogen igniter, and a method for the repeated use of such a system. The igniter and the system can be used in a nuclear reactor facility.
Abstract:
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.
Abstract:
A self-igniting gas burner which includes, generally, an oxidation catalyst which is supported by means of a gas-permeable catalyst support plate. A mixture of gaseous fuel is supplied to and permeates through the catalyst support plate. In doing so, the gaseous fuel is oxidized to cause combustion. The combustion of the gaseous fuel heats the catalyst support plate which then radiates heat to a load. The hot products of reaction also pass through the catalyst support plate, to heat the load.
Abstract:
A method and fuel composition for pre-heating and/or operating a catalytic heater is described herein. In one aspect, there is provided a method of preheating a catalyst in a catalytic heater comprising the steps of: providing a preheat composition comprising greater than 60% by volume hydrogen and at least one fluid component selected from natural gas, propane, butane, refinery off gas, ethylene off gas, methanol, ethanol, butanol, liquefied biogas and mixtures thereof; and contacting the catalyst with the preheat composition for a period of time sufficient to raise the temperature of the catalyst to a one or more temperatures. In this or other embodiments, there is a fuel composition that comprises at least one component selected from natural gas, propane, butane and mixtures thereof and optionally hydrogen.
Abstract:
An apparatus for initiating ignition of a combustible material, the apparatus including an igniter assembly having a support, a catalytic material carried by the support, the catalytic material comprising a substance which reacts with a hydrogen-containing gas in the presence of an oxidizing gas to produce an exothermic reaction and a temperature sufficient to cause auto ignition of the hydrogen containing gas, a source of hydrogen-containing gas and a source of oxidizing gas.
