Abstract:

Abstract: The air preheater tripped repeatedly caused by unknown reasons.In order to solve this problem, the frequency converter control cabinet of the air preheater was reformed. The
driving mode of the air preheater was changed.The air preheater is driven by frequency converter in startup process, and then the air preheater is driven by 50 Hz auxiliary power during normal operation.The safe and economical operation of the unit was ensured.
