RECOVERY CYCLE Kraft recovery boiler operation with splash plate and/or beer can nozzles-a case study

摘要

In this work,researchers study a boiler experiencing upper furnace plugging and availability issues.To improve the situation and increase boiler availability,the liquor spray system was tuned/modified by testing different combinations of splash plate and beer can nozzles.The tested cases included:1) all splash plate nozzles(original operation),2) all beer can nozzles,and 3) splash plate nozzles on front and back wall and beer cans nozzles on side walls.The researchers found that operating according to Case 3 resulted in improved overall boiler operation as compared to the original condition of using splash plates only.
