Main features of heat transfer oil used in heat transfer oil boiler
The heat transfer oil has the characteristics of heat-resistant cracking and chemical oxidation, high heat transfer efficiency, fast heat dissipation and good thermal stability. As a heat transfer medium for industrial oils, heat transfer oils have the following characteristics: a high operating temperature can be obtained under almost normal pressure conditions. In other words, the working pressure and safety requirements of the high-temperature heating system can be greatly reduced, and the reliability of the system and equipment can be improved; the process requirements of heating and cooling at different temperatures can be met in a wider temperature range, or can be the same The same system is used in the system. The heat transfer oil simultaneously meets the requirements of high temperature heating and low temperature cooling.
In other words, the complexity of the system and operation can be reduced; the water treatment system and equipment are eliminated, the thermal efficiency of the system is improved, and the maintenance workload of equipment and pipelines is reduced. That is to say, the initial investment and operating costs of the heating system can be reduced; in the case of system leakage caused by an accident, the heat transfer oil may burn when exposed to an open flame, which is a problem compared to the heat transfer oil system. However, in the absence of leakage, since the heat transfer oil system operates under low pressure conditions, its operational safety is higher than that of water and steam systems.
Compared with the molten salt of other types of high temperature heat transfer media, the heat transfer oil has an advantage over the heat transfer oil in the price and service life of the heat transfer medium at an operating temperature of 400 ° C, or higher, but other aspects. Obvious disadvantages, especially in terms of the complexity of system operation.
Chemically stable, not as easy to burn as light oil. From the point of view of use and safety, its main feature is
1. Better thermal stability, less coking and longer service life in the permissible temperature range.
2. Good thermal conductivity, fluidity and pumpability in the permissible temperature range.
3. Low toxicity, no odor, no corrosion equipment, and little impact on the environment.
