Abstract

Abstract: The boiler MFT accident of the 335 MW unit in a power plant caused by the failure of the power supply of pulverized coal feeder was analyzed in depth. In order to avoid similar accident, the control method of the pulverized coal feeder had been improved accordingly, which provides reference for similar problem handling.

Key words: boiler, main fuel tripping (MFT), intelligent automation system, pulverized coal feeder, control
