热媒炉导热油使用状况分析

Application Analysis on Heat Conducting Oil of Heat Medium Heater

以中洛输油管道热媒炉导热油为例，分析了热媒炉导热油使用寿命缩短的主要原因是超高温运行，局部过热，无氮封杂质较多等，邮采取旁接流程，加设冷封阱隔绝空气过滤和精制措施，以延长导热油使用年限。以三四年为一个使用周期计算，若将导热油延长一个使用周期可节约１００×１０＾４元。

Taking the heat conducting oil used in Zhongmu--Luoyang oil pipeline as an example,the problem on service life of heat conducting oil of heat medium heater is studied. The result shows that the high temperature operation,local superheating,nitrogen isolation free,and high impurity shorten the service life of heat conducting oil. In the light of the problems,some countermeasures against the problems,such as adopting by-pass dilatetion tank process,installing a cooling tank to isolate air,and heat conducting oil filtering and refinement,are put forward. Taking 3 or 4 years as a service period into account,expanding a service period of heat conducting oil could save a cost up to 100 ×104 yuan.
