What is the enthalpy of heat transfer oil and what is the boiling point of heat transfer oil

The enthalpy of general heat transfer oil is basically determined. Because heat transfer fluids are organic. The thermophysical data for all organic matter are not far apart.

Why is the enthalpy specific and is it hot enthalpy? What about datum points? It is better to give you a more practical "specific heat" and thus calculate it yourself:

Generally, the heat capacity of heat transfer fluids is about the same. 100 by design, 150 by design, 200 by design. These figures will not deviate from the actual data by more than 5%. When conducting a safety assessment, the safety factor can be enlarged or reduced by 10% or 20% according to the safety direction.

usuallyHeat transfer fluidThe flash point in the open cup is 210 up and down 20 range. Heat transfer oil is a special oil with good thermal stability that is used to indirectly transfer heat.

Due to its uniform heating, accurate temperature control, it can be used at low vapor pressure.

It has the characteristics of high temperature, good heat transfer effect, energy saving, convenient transportation and operation, etc., and has been widely used in various occasions in recent years, and its use and dosage are increasing.

Thermal stability is the most important performance of heat transfer fluids. Depending on the thermal stability, the degree of pyrolysis and polymerization in its use varies. Thermal cracking produces small molecule low boiling matter, which is easy to cause gas resistance in the system and cavitation in the pump.

At the same time, it also causes high evaporation loss and environmental pollution of oil products.

Thermal polymerization produces macromolecular hyperboiling matter, which is gradually deposited on the surface of the heater and pipeline, and the carbon deposits formed will affect the heat transfer efficiency and temperature control accuracy of the system. The L-Q series heat transfer fluids are selected from base oils with excellent thermal stability.

and additives, so the product has excellent thermal stability.

Oxidative stability is another important performance of heat transfer fluids. Open systems or expansion tanks that are not enclosed by nitrogen will cause oxidation reactions at the interface between oil and air.

Generally speaking, under conditions higher than 60, the oxidation of the oil will occur when it comes into contact with the air, and the oxidation products will gradually form gum and sediment, which will adhere to the heater and pipeline surface and produce carbon deposits.

Usually the flash point of heat transfer oil in the open cup is 210 up and down 20 range, that is, you have not seen the boiling has burned, and the boiling point of ordinary mineral oil in the closed system is below 350.

About 350 degrees Celsius. There are slight differences between models.

There are different compositions of heat transfer oils, and the boiling point is generally very high.

The expansion coefficient of the heat transfer oil before shouting, the temperature is also high, and the more carbon deposition in the coking is certain, it is best to use it at the highest operating temperature allowed to be used. The above is the answer of Shandong Enkeli heat transfer oil for you, I hope the answer can help you.

The maximum operating temperature of L-QB heat transfer fluid is 300 °C, the maximum operating temperature of L-QC heat transfer fluid is 320 °C, and the maximum operating temperature of L-QD heat transfer fluid is 350 °C.

Heat transfer oil has the properties of thermal cracking resistance and chemical oxidation, good heat transfer efficiency, fast heat dissipation, and good thermal stability. As a heat transfer medium for industrial oils, heat transfer oil has the following characteristics: high operating temperatures can be obtained under almost atmospheric conditions.

That is, it can greatly reduce the operating pressure and safety requirements of the high-temperature heating system, and improve the reliability of the system and equipment; It can meet the process requirements of heating and cooling at different temperatures in a wider temperature range, or realize the process requirements of high-temperature heating and low-temperature cooling with the same heat transfer oil in the same system.

Generally, the flash point of heat transfer oil in the open cup is 210 up and down 20 range, that is, no boiling has been observed to burn, and the boiling point of ordinary mineral oil in the closed system is below 350.

Heat conduction oil is the former name of "heat carrier oil" in GB T 4016-1983 "Terminology of Petroleum Products", which is used to indirectly transfer heat and is a special oil with good thermal stability. Because of its uniform heating, accurate temperature control, high temperature under low vapor pressure, good heat transfer effect, energy saving, convenient transportation and operation, etc., it has been widely used in various occasions in recent years, and its use and dosage are increasing.

At 104 degrees, the trace amount of water contained in the heat transfer oil boils and vaporizes, which is like the heat transfer oil itself boiling in a confined space. Let's degas first on the first run. As the temperature rises, volatiles will come out.

The boiling point of heat transfer oil is 250 degrees, 280 degrees, 300 degrees, and 350 degrees.
