A Study of the Digital Image Processing and Diagnosis Method for a Single Burner Flame

On the basis of pulverized coal combustion theory and digital image processing technology proposed is a method for the diagnosis of the on/off status of a burner flame. The method features three conditions, namely, the presence of a projection flame front, the irregular shifting motion of the latter's location, the variation of the latter's average gradient value. With the help of the above method it is possible to guide combustion operations and help FSSS (furnace safeguard supervisory system) to ensure furnace safety protection.
