Flame Failure Detection Systems as Applied to Glass Melting Tanks and Annealing Lehrs

Recent advances in both design technology and installation techniques of optical flame detectors have now made possible and practical the reliable use of flame failure detection systems for burners used on glass melting tanks and annealing lehrs. This paper will cover the operating characteristics of various types of flame detectors and a description of flame safeguard control systems as applied in the glass manufacturing process. In addition, we have prepared a review of current industry recommendations and insurance underwriters´ requirements for burner safeguard systems for the glass industry.
