How does an optical flame detector detect a fire?
Every combustion process emits 3 types of energy: 1. Heat energy – detected by heat detectors 2. Radiation energy – detected by optical detectors 3. Product energy – contained in unburned products and unstable products of combustion. The fastest method to detect the above energies is the Optical analysis of the radiation emitted in a combustion process. The Optical detectors detect the radiation energy emitted by the chemical processes that take place in a fire.
