Abstract

Abstract: The abnormal current of main motor occurred in air preheater operation was analyzed deeply, the scheme for solving this problem was proposed, and relevant measures were adopted. After the improvement, the air preheater operated safely, and the reliability and economic efficiency of equipment were raised greatly.

Key words: air preheater, main motor, auxiliary motor, frequency converter, improvement of external gear oil pump
