用于锅炉余热回收的新型低温省煤器设计

Design of the New Low-level Stack-Gas Economizer Applied in the Boiler Waste Heat Recovery

叙述了燃煤锅炉受热面低温腐蚀的机理,提出了1种能够减轻低温腐蚀和堵灰并有效回收锅炉排烟余热的新型低温省煤器的设计思想。

This paper analyzed the mechamsm of low temperature corrosion on the heat-absorbing surface in coal burning boilers,and the new type of low temperature coal saver which can relieve the low temperature corrosion and ash clogging was proposed to recover the boiler＇s flue gas heat.
