Abstract
Flame-based detectors having an ignitor are protected from corrosion by flowing a protective gas over the ignitor. The protective gas layer protects the ignitor from corrosive components in exhaust gas.
Claims20
A flame-based detector comprising:
- a housing having an upstream region and a downstream region;
- a burner disposed within the upstream region of the housing;
- a fuel flow path for providing a flammable fuel to the burner;
- an air flow path for providing air to the burner;
- a collector within the housing, wherein the collector is an ion collector or a photon collector;
- an ignitor in the downstream region;
- a protective gas port upstream from the ignitor and configured to flow a protective gas over the ignitor;
- and
- an exhaust vent at the downstream region of the housing for discharging exhaust gas from the housing.
