Abstract

In coal gasification plants, coal ash is discharged as molten slag. If the molten slag solidifies and is not discharged, an operator who monitors the plant throughout the day ignites a melting burner and removes the solidified slag. However, the use of this burner decreases the efficiency of the gasifier. Therefore, objective and appropriate automatic decision of ignition timing for the slag melting burner is necessary for economical operation, thereby reducing the operator's work load. In this report, we propose a decision index for ignition timing of the melting burner using monitoring videos. We have evaluated our method using 54 actual monitoring videos, and we have shown the applicability of automatically deciding the ignition timing.
