A practical fiber optic air-ratio sensor operating by flame color detection

摘要: This article discusses the development of a simple fiber-optic sensor used to detect air-ratio in premix type gas boiler, by monitoring and appraising color flame emission, including effect radical emissions. Such boilers with multi-port plate burner show an improved thermal efficiency, environmentally friendly reduction both NOx CO exhaust gas. The is monitor maintain order enable effective feedback control, low-cost, durable small solution presented. Tests carried out potential for use outside laboratory image processing techniques are analyze spectral features emissions seen confirm regions sensor.
