燃焼状態監視要素としての火炎検出器の適用性について

抄録

The automation of oil fired boilers requires a combustion monitor capable of detecting flame and of judging the combustion conditions.
This paper reports that in order to develop highly reliable and low cost monitors, the applicability of the flame detectors now in use is investigated from the following points of view:
(1) Actual results of existing flame detectors
(2) The method of judgement of the combustion conditions by scanning the stable zone in the flame
As the result of above investigation, the flame detectors which have one of following methods can be used as the combustion monitor.
(1) Method using the ultraviolet ray in the flame by discharge tube
(2) Method using the brightness variation (Flicker method)
(3) Method using the brightness intensity
(3) Method combining the ionized current with the electric conductivity in the flame
