Fuel ignition system and method of making the same

摘要

A fuel ignition system and method of making the same are provided, the system having a unit for detecting when an igniter has been heated to ignition temperature, the detecting unit comprising a receiving member for receiving at least some of the electrons emitted from the heated igniter and an electrical circuit for determining from the received electrons an emission rate of the electrons and for operating a fuel feeding device to feed fuel to a burner only when the determined emission rate is at a certain level that proves that the igniter is at ignition temperature.
