Thermo oil plants Heat transfer almost without pressure
The world’s largest thermal oil plants can be found in parabolic trough solar power plants in which the irradiation is focused by parabolic-shaped mirrors onto a vacuum-insulated absorber pipe running along the focal line in which a special heat transfer fluid (thermal oil) flows and is heated up to max. 400 °C.
Preventing Fires in Thermal Oil Heat-Transfer Systems
Heat transfer systems typically and routinely operate at temperatures well in excess of their fluid’;s flash and fire points, but never in excess of their AIT. Relatively few fires have originated in thermal fluid systems. Most of those that do occur are insulation fires, or are caused by loss of flow, cracked heater tubes or leakage.
Thermal Oil an overview ScienceDirect Topics
The use of the same molten salt in the solar field and in the thermal storage system has clear advantages, because the molten salt currently used has good thermal stability up to 575 °C (175 °C higher than the oil) and the overall plant configuration would be simpler, because the oil/molten-salt heat exchanger now needed in current plants would no longer be needed. However, the

Don't Fall For Common Myths About Hot Oil Systems
Because liquid-phase thermal fluid systems operate under moderate pressure — typically a maximum of 100 psig at the circulation pump discharge — a leak will result in a fluid discharge into the surrounding area. Most thermal fluids have a flash point between 300°F and 450°F (some have a flashpoint as high as 530ºF but their high viscosity limits their usefulness) and can't produce
