Abstract
A flame powered intermittent pilot combustion controller may include a first power source and a second power source separate from the first power source, a thermal electric and/or photoelectric device, an igniter and a controller. The thermal electric and/or photoelectric device may charge the first power source when exposed to a flame. The controller and the igniter may receive power from the first power source when the first power source has sufficient available power, and may receive power from the second power source when the first power source does not have sufficient available power.
