We have an IR flame detector oriented to the incinerator where the temperature can reach 900°C.
Recently, we had so many times false detections and we suggested it was due the high temperature in the incinerator, because it is Infra-red detector, it can detects corpses by the energy given off them. So we changed the orientation a little to only meet the fuel gas skid more than the incinerator .
For me, the IR detectors only detect element given off hot gases like CO2 or H2O and cannot see energy from hot bodies.
But the question I want to ask, is the detection it was made frequently was by the CO2 and H2O given off from combustion reactions inside the incinerator (is it possible the detection comes from behind the body of the furnace?) or is it really due to the temperature??!!!
Thank you very much.
