1. Hidden danger of air and moisture entering
In the process of heating and starting, the exhaust valve should be repeatedly opened to drain the mixed steam of air, water and heat transfer oil in the system, and pay attention to control the heating rate of heat transfer oil.
2. Prevention of hidden danger caused by quality decline of heat transfer oil
For the heat transfer oil in use, the "Supervision Regulation on safety technology of organic heat carrier furnace" stipulates that the kinematic viscosity, flash point, residual carbon and acid value shall be tested at least once a year.
3. Hidden danger of coking and carbonization of electric heating rod
When the heat transfer oil is heated by the electric heating rod, the surface of the electric heating rod will be carbonized quickly, and the electric heating rod will be burned out and the heat transfer oil will be scrapped. The best solution is to design and manufacture special electric heating rod, increase the surface area, and make the surface temperature lower than the allowable liquid film temperature of heat transfer oil.
4. Hidden danger of leakage between pipe flange or valve
All seals in the pipeline system shall be flexible and metal wound products with good sealing and flame retardancy, and seals containing rubber components shall not be used. Thermal insulation materials should be made of materials with small voids and not easy to be impregnated by organic heat carriers, so as to prevent the insulation layer from catching fire after the leakage of organic heat carriers.
