Paper Abstract

Many infrared flame detectors are now available which detect the presence of a flame by sensing radiation at or near 4.3 microns in the middle infrared. However, the radiation spectrum produced in this wavelength band, largely due to the hot carbon dioxide produced in the flame, is modified in transmission through the atmosphere from the flame to the detector. A study of these changes has shown that they can be used to gauge the distance of the flame from the detector. Some preliminary results from a detector built to provide this type of information are reported and the advantages that the technique can provide in terms of fire detection systems are also considered.
