Maintenance and Cleaning of Thermic Fluid System
...............................................
B. Initial Start of TFS
1. Check system leakages at 7 kg/cm2 pressure from dry air or nitrogen,
2. Fill the oil from expansion tank and remove air form system through vents,
3. Run system for 30 minutes to remove trapped air from system and do this till you have stable pressure in the system,
4. Start Fire and raise the temperature of the system up to 99 OC,
5. Increase temperature by 2 OC in every 15 minutes and keep eyes on expansion tank to see any steam coming out of the
system,
6. If steam comes out you observe any vibration in the pressure gauge and some of the pipelines, don’t increase temperature till
all comes to stable condition,
7. After attaining temperature up to 120 OC check the whole system by laser temperature sensor gun, that no area should have
temperate below 110 OC,
8. If o.k. then increase temperature as per point 5.
9. After required temperature achieved check full system for any leakage.
