需要急冷的烟气在化工流程中，往往烟气需要在一个规定的时间内，冷却到一个规定的温度。由于余热锅炉热交换在时间方面的严格限制，这就在现实的烟气通道长度的结构条件下，规定了烟气的流速。对于这种烟气，目前烟管锅炉与水管锅炉皆有所应用。但如果烟气在受热面上积灰结焦的可能性较大时，则往往倾向于采用烟管锅炉。为此目的，现代余热锅炉技术发展了不少类型的烟管锅炉，获得一定的成功，如：双套管型直烟管锅炉，采用扁圆集管可以吸收直烟管的热膨胀差，和承受高温烟气的直接冲刷；双套管与螺旋管相结合的烟管锅炉，有结构紧凑、可以采用烧焦操作等特色。7高露点烟气对于高露点烟气，为了防止腐蚀、结垢、堵灰等运行问题，余热锅炉设计的基本要求是避免受热面上的结露。目前通用的办法是使锅炉受热面的金属壁温在任何操作条件下都高于露点温度，具体的措施有：选择适当的锅炉汽水侧的工作压力，使对应的炉水饱和温度高于烟气露点温度；避免低于饱和温度的炉水与受热面接触，因此要对锅炉水进行充分的混和与预温，并且要避免采用相当于燃烧锅炉的省煤器的那种低温区段；在操作上，为防止锅炉在低负荷和停炉时的结露，往往需要采取适当的保温措施。


FKM与FPM其实都是氟橡胶的缩写，只是FKM是欧洲的拼写缩写，FPM是美国的拼写缩写。氟橡胶可以分为三种基本类型：即氟碳橡胶、氟硅橡胶、氟化磷腈橡胶。氟橡胶是特种合成弹性体，其主链或侧链上的碳原子上接有电负性极强的氟原子，由于C-F键能大（485KJ/mol），且氟原子共价半径为.64A，相当于C-C键长的一半，因此氟原子可以把C-C主链很好地屏蔽起来，保证了C-C链的稳定性，使其具有其它橡胶不可比拟的优异性能，如耐油、耐化学药品性能，良好的物理机械性能和耐候性、电绝缘性和抗辐射性等，在所有合成橡胶中其综合性能佳，俗称橡胶王。



经常观察冷却水系统、压缩空气系统的进口温度冷却水水温2~32℃；水压.15~.3Mpa；压缩空气进气温度一般应45℃（以手摸进气管不烫为宜），特殊除外。冷却水应保持清洁，Y型过滤器半个月清洗一次，水质好每月一次；水冷凝器每年清洗一次（具体视水质而定），风冷凝器每个月清洗一次.风冷凝器的清洗，应尽量避免压伤风冷凝器翅面风冷凝器的周围应保证足够的空间通风散热，不能在太阳光直射下工作；定期用压缩空气清除表面积灰，清洗用压缩空气的流量、压力不可太大。
