This study is aiming at establishing the relationship
\r\nbetween the optical signal of flame and an equivalent ratio of flame. In
\r\nthis experiment, flame optical signal in a furnace is measured using
\r\nphotodiode. The combustion system is composed of metal fiber burner
\r\nand vertical furnace, and flame chemiluminescence is measured at
\r\nvarious experimental conditions. In this study, the flame
\r\nchemiluminescence of laminar premixed flame is measured using
\r\ncommercially available photodiode. It is experimentally investigated
\r\nthe relationship between equivalent ratio and photodiode signal. In
\r\naddition, the strategy of combustion control method is proposed using
\r\nthe optical signal and fuel pressure.
\r\nThe results showed that certain relationship between optical data of
\r\nphotodiode and equivalence ratio exists, and this leads to the
\r\nsuccessful application of this system for instantaneous measurement of
\r\nequivalence ration of the combustion system.<\/p>\r\n","references":"[1] Sewon Kim, Chang Yeop Lee, Minjun Kwon, \"Real-time Integrated\r\ncontrol system to improve boiler efficiency,\" Research of Energy\r\nEfficiency & Resources, Annual report in 2013.\r\n[2] B.
