摘要(Abstract)：

阐述了引起燃煤锅炉空预器堵塞的机理及在新排放条件下其堵塞问题的新特点,详细介绍、分析新排放条件下解决和消除燃煤机组空预器堵塞的各种技术方法、特点和应用效果,如控制硫酸氢铵生成、控制空预器壁温、空预器吹灰、空预器在线水冲洗、单侧空预器升温等,提出了解决空预器堵塞问题的新思路。
The paper introduces clogging mechanism of the air preheater of coal-fired boiler and the new clogging characteristics under new emission conditions; besides, it introduces and analyzes various technical solutions to air preheater clogging of the coal-fired units such as controlling the formation of ammonium hydrogen sulfate, controlling the wall temperature of the air preheater, air preheater soot blowing, on-load air preheater flushing and temperature rising of single-side air preheater, as well as characteristics and application effect. A new approach for preheater clogging handling is also proposed.
