HTF heat transfer in two basic ways: in the initial boiling point or below the boiling temperature of the liquid phase heat transfer mode; in the gas phase at a temperature above the boiling point of the heat transfer mode. The so-called maximum temperature refers to preheat conduction system efficient and safe operation of a direct relationship with a temperature limit, that the highest temperature and maximum film temperature. Refers to the maximum temperature in the recycle line from the heater out of the measured maximum allowable temperature of the main body. If the actually measured temperature is higher than this temperature, the main body of a large number of cleavage occur. Maximum film temperature is within the fluid flowing through the heater tube in contact with the heater boundary layer maximum allowable temperature synthetic heat transfer oil supplier, this temperature is equal to the inner pipe wall heater temperature. When the temperature is higher than the actual film temperature, a large amount of the liquid boundary layer cracking will occur, in general, the maximum allowable temperature plastic film measuring high temperatures up to about 20 ℃. In actual use, synthetic heat transfer oil, the main body of the process temperature is lower than the maximum operating temperature required for the selected product, from the design point of view to ensure that the temperature inside the heater pipe below the maximum film temperature. The other method of determination of the thermal stability of a thermal oil GB / T 23800 is sealed under nitrogen, heating oil after 720h or 1000h synthetic HTF standards, deterioration rate is calculated to be less than or equal to 10% of the qualified. This nitrogen seal oil furnace system is very good, but for the vast majority of China's oil furnace is no blanketing systems are systems and direct contact with the air, this is a big problem, sealed under nitrogen outperformed synthetic HTF models, not necessarily in the non-nitrogen seal performance or. About the extensive use of temperature encountered only 200 ℃, only use 2-3 years to be scrapped, is indicative of the problem.
