Abstract

Abstract: The leakage of CFB boiler is can not be avoided; and when the leakage occurs, the boiler must be stopped to treat the leakage fault. So it is necessary to find the leakage as early as possible, at early or medium stage of the fault. The leakage phenomenon of the 300MW CFB boiler and the history curves of relevant parameters in leakage process were analyzed. The optimized measures of alarm logic of boiler leakage were put forward and implemented; then the MFT triggered by serious leakage is avoided; the accident expansion is prevented; and the live of the boiler is lengthened.
