Abstract
The system utilizes a radiation sensing device which views an electrically heated emissive igniter to provide proof-of-ignitability detection of the igniter. Optimally a photovoltaic array may be employed to self-power the electronic circuitry and fuel intake valve to the burner of a combustion device. In one embodiment there is also provides a second emission device viewed by the first photovoltaic array or a second photovoltaic device which views a second emissive device which is thermally heated upon activation of the burner. The electronic signals generated by the second light sensing device can be used to prove ignition of the combustion gases. When the second light sensing device is a photovoltaic array, power may be generated for recharging a storage battery, which in turn, can be used to electrically heat the emissive igniter. In the simpler case where the second emissive device is powered by the gas flame, means are provided for turning off the igniter. Thermal sensing may be provided to verify temperature of the system. The system thereby provides a means for affording the significant safety features of proof-of-ignitability and proof-of-ignition to a combustion apparatus.
