The thermopile heat of combustion detector is at the heart of each heating value transmitter. Air is used as a heat transfer media and flows around the combustion chamber. Any increase in the heat produced by the combustion of a controlled sample of process gas is immediately sensed and reported to the microprocessor. Air enters the combustion chamber on the outside cold junctions where its heat is measured, then flows down the outside of the thermopile towards the viewer to turn through 180° past the end of the thermopile assembly and then flows up through the heat exchanger ... to mix with the heated flue gases from the burner.  3, record 1, English, - combustion%20detector

As a supplement for the analysis of combustible organic vapors, Behrendt designed a combustion detector which registers the volume increase resulting from the formation of new molecules when organics in the nitrogen carrier gas stream are burned at atmospheric pressure over heated copper oxide in a silica combustion chamber to which is attached a microburet. In principle, the gas amplification within the detector increases with molecular weight of the substance.  1, record 2, English, - combustion%20detector
