I don't have a clear picture of what you are trying to do. If you are trying to light a burner and maintain the flame in the burner you might take a close look at appliances with electronic ignition systems. Many new gas (natural or propane) water heaters, furnaces, clothes dryers, etc use electronic ignition or a hot surface type of ignition system. They may produce some momentary noise but the noise is not continuous. Another approach might be to use a spark to ignite a pilot - so the spark need only be momentary.
Good luck with your project.
