Abstract

Abstract: The constructions of return cone valve and deslagging cone valve in domestic 300 MW CFB boiler were introduced, the problems often occurred in the two cone valves operation were described, and the reasons causing these problems were analyzed. Aiming at these problems, the relevant measures were proposed, the implementation of these measures enhanced the safety of unit operation.

Key words: CFB boiler, return cone valve, deslagging cone valve, fault reason, analysis, measure
