oil flushing of thermal oil is not as important as systems like hydraulic or lubricating ones, so first of all, take it easy;
Two major purposes to have oil flushing:
1. collect all knid of dirt into the filters so that you can clean
2. get rid of air inside the system
It is often a process that during oil flushing, you run the buner and gradually raise the temp high enough to evaporate water in the system, the system thus will be ready to be heated up once oil flushing process is finished.
During this process, it is strongly recommended that you open all consumers, or as many as possible, to enable the system to be ready to max extent.
Then safety first, cos it's gonna be hot.  |
