內(nèi)容簡介A malfunction in combustion with a gas or oil burner in a high temperature industrial kiln or boiler can result in a serious accident in the absence of a burner flame detection system and an optimum procedure for handling the firing stoppage. In order to prevent such an accident, it is necessary to select a reliable flame detection system to distinguish radiation from the flame in comparison with radiation from the furnace wall. The spectroscopic distribution of radiation from a Bunsen burner flame and from a water cooled refractory wall during gas and oil combustion was measured using spectroscopic radiation equipment. It was found that the radiation from the flame in the ultra violet range was relatively large in comparison with the radiation in this range from the wall. Further, in the visible light and infra-red range, it was found that the radiation from a gas fired flame was masked by the radiation from the wall and it was difficult to distinguish the combustion flame from the high temperature wall. However, in the case of an oil burner flame, radiation in the range of visible light and infra-red was stronger in the flame than from the furnace wall, and therefore in this radiation range it was confirmed that the burner flame detection is effective.
