Analysis of superheater's pipe wall overtemperature by fault tree diagnose

Abstract: After research on a 2000 t/h subcritical forced-circulation balanced ventilation were applied boiler and the structure and operation of its auxiliary system builds up this heat transfer model of a superheater's pipe wall and analyze the effect of primary factors on the overtemperature of the pipe wall. Fault tree structure was used to uncover the multiplayer logic between the overtemperature of the superheater's pipe wall and the faults.

Key words: Fault tree, Superheater, Overtemperature, Diagnose analyze
