催化裂化装置余热锅炉设计特点

Design features of transfer line heat exchanger in FCC unit

利用催化裂化装置高温烟气,安装余热锅炉发生蒸汽,炉体不仅占地少,而且采取了加强密封、炉管吊挂等结构,解决了炉墙冒烟、鼓包及炉管烧坏等问题。

To utliiize high temperature flue gas from FCC unit,transfer line heat exchanger is installed to generate steam. The body of the heat exchanger occupies less space and is constructed by mean of reinforcing seals and hanging coils,thus solving many problems such as wall smoke,wall bubbles and coil breakage.
