回转式空预器漏风原因分析及对策

Analysis and Countermeasure of Rotary Air Preheater of Air Leakage

回转式空气预热器漏风、卡涩、蓄热片损坏是回转式空预器在目前应用过程中产生的主要问题。针对回转式空预器在运行过程中产生的漏风问题展开研究,分析漏风问题对空气预热器乃至锅炉设备的危害,并提出漏风率的测定和计算方法,同时,结合案件实例研究防范对策和改造方案,采取积极的措施降低回转式空预器的漏风率,对保障锅炉设备的稳定运行和经济效益的增长具有重要的参考意义。

Air leakage,jamming,thermal film damage of rotary air preheater are the main problem during the application.Study on the air leakage during operation of rotary air preheater and analysis on air leakage problem of it and damage of boiler equipment to get the air leakage rate measurement and calculation method.Take positive measures to reduce the rate of air leakage of rotary air preheater and combined with practical examples to study on preventive measures and improvement,it has great reference significance for stable operation of boiler equipment and economic growth.
