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 of synthetic heat transfer oil, that is 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 maximum allowable temperature, 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, the main body temperature is lower than the technological requirements of the selected product the highest temperature synthetic heat transfer oil wholesale, from the design point of view to ensure that the temperature inside the heater pipe below the maximum film temperature. Even if all of the HTF have tested the thermal stability and thermal oxidation stability and are qualified through extensive testing after thought in actual use will still coke, but how many different brands between the amount of coke is different high-temperature synthesis conducting oil, deterioration of the state is different. This shows that these two methods of testing and coke or not is not very strong correlation between synthetic heat transfer oil manufacturers, coke amount is not known how much more of. All HTF scrap and coke are a relationship, if conducting oil and coke, carbon residue would not be a substantial increase, oil will not be scrapped.
