Abstract: In order to increase the safety and stability of the dry and wet states transition process of supercritical unit, the reasons of accident shutdown, which had happened in dry and wet states transition process of a 600MW supercritical unit, were analyzed; and it is considered that the main reason caused the accident is maladjustment of the watercoal ratio. In dry and wet states transition process, must pay attention to adjust the watercoal ratio to ensure the stability of pressure and temperature of main steam.
Key words: supercritical unit, dry and wet states transition, water-coal ratio, reason of accident
