一种设置强化传热构件的急冷锅炉
摘要：
本发明公开了一种设置强化传热构件的急冷锅炉。本发明的急冷锅炉包括换热管和壳层，在所述的急冷锅炉的换热管中设置强化传热构件；且所述的强化传热构件设置在急冷锅炉壳程流体中汽相占所述流体的体积百分比小于5％的位置或者所述急冷锅炉管程流体温度高于520℃的位置。本发明的急冷锅炉应用于乙烯裂解装置中，能够强化急冷锅炉的传热效果，延缓急冷锅炉的结焦，从而延长急冷锅炉的在线时间。
摘要（英）：

The invention discloses a quenching boiler provided with an enhanced heat transfer member. The quenching boiler comprises a heat exchange pipe and a shell layer. The enhanced heat transfer member is arranged in the heat exchange pipe of the quenching boiler and is arranged at a position where a vapor phase in shell-side fluid of the quenching boiler accounts for less than 5 volume percent of the fluid or at a position where the temperature of the shell-side fluid of the quenching boiler is higher than 520 DEG C. The quenching boiler is applied to an ethylene cracking device, can enhance the heat transfer effect of the quenching boiler, and delays the coking of the quenching boiler so as to prolong the online time of the quenching boiler.
