Method and apparatus for igniting well heaters
Patent
·
OSTI ID:5944340
Ignitors are provided for initiating fuel fed well heaters located adjacent earth formations in a well bore. The ignitors are battery powered and subsist independently downhole. Batteries are used to provide current to a heating element or, in conjunction with an oscillator and transformer can be used to generate an electric arc using a spark gap. Additionally, a catalytic ignitor can be used in conjunction with a hydrogen containing fuel gas, thereby providing a spontaneous hydrogen and air reaction. The hydrogen-air reaction raises the temperature to that of natural gas ignition. (7 claims)
