Abstract

Abstract:

Through analysis, it is found that the twostage moving blade adjustable axial flow fan is frequently jammed because of the design, maintenance, operation mode and so on. According to the practice, the prevention, countermeasures are discussed and the improvement opinion is put forward，considering the design improvement, operation maintenance and overhaul. It can provide a reference for jamming issues of induced draft fan with similar condition.

Key words:

induced draft fan, moving blade adjustment, fault, preventive measures
