Problems with the dehydration cycle of heat transfer oil
Thread Content
During the initial startup cycle for water removal, does the heat transfer oil circulate only within the oil furnace? Should we still circulate the fluid including the pipes of the heating equipment?
Is there a separate dehydration method for the pipes leading to the equipment and for the equipment that uses heat transfer oil? It is recommended to carry out dehydration simultaneously, as this allows for the inspection of both the pipes and the equipment at the same time
The entire system should be put into a large-scale cycle to raise the temperature and remove moisture together. Gradually increase the oil temperature at the outlet of the heating furnace; all the oil that returns to the furnace first enters the expansion tank to allow the water vapor to evaporate.
To cycle together, all heat transfer oil must be dehydrated and dehydrogenated, and the pipelines must be inspected for leaks and tightened.
A large-scale circulation is required; some water may remain in the equipment pipes. If the heat transfer oil is heated separately and then enters the pipes where there is liquid water present, it can be dangerous. The heating of the heat transfer oil must be done gradually to ensure that any water vapor can be released in a timely manner
