ANALYSIS AND PREVENTION OF DAMAGE TO REFRACTORY MATERIALS IN THE TARGET AREA OF CIRCULATING FLUIDIZED BED BOILER SEPARATORS
With the increasing requirements of national environmental protection indicators,circulating fluidized bed boilers need to undergo standard upgrading for desulfurization and denitrification.After denitrification transformation,the refractory material in the target area of the separator was frequently detached,leading to the steam cooling tube embedded in the refractory material cracked by high speed flue gas scouring.By analyzing the detachment reason,optimizing the denitrification system and refractory materials,and taking prevention measures,the life of the refractory material was greatly increased.
