The heat transfer oil has the properties of resistance to thermal cracking 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: Under almost normal pressure conditions, high operating temperatures can be obtained. That is, the operating pressure and safety requirements of the high-temperature heating system can be greatly reduced, the reliability of the system and equipment can be improved, the process requirements of heating and cooling of different temperatures can be met in a wider temperature range, or the same type can be used in the same system. The heat transfer oil simultaneously achieves the process requirements of high temperature heating and low temperature cooling. That is, the complexity of the system and operation can be reduced; the water treatment system and equipment are omitted, the thermal efficiency of the system is improved, and the maintenance workload of equipment and pipelines is reduced. That is, the initial investment and operating costs of the heating system can be reduced.

      Heat transfer oil is mainly used in textile printing and dyeing, such as drying setting device, hot melt dyeing device, dyeing printing device, dryer, dryer, calender, flattening machine, washing machine, rolling mill, ironing machine, hot air pulling Heating such as web. In the synthetic fiber industry, heat transfer oil furnaces are mainly used for heating, melting, spinning, thermosetting, fiber finishing, stretching and drying equipment.

   With the expansion of the application range of the heat-conducting oil furnace and the increase in the number of products used, in order to save money, the company may have a lack of experience in the furnace and the wrong operation, or the phenomenon of not being certified. In fact, these can cause fatal harm.

   1. In the event of a sudden power outage, we must quickly remove the fire from the furnace, stop it from continuing to burn, and inject a large amount of cold air into the furnace to achieve cooling. At the same time, we need to open the cold oil replacement, open the oil drain valve, put the oil into the position tank, and let the cold oil in the position tank flow back into the furnace to remove the heat and avoid the harm.

   2, we must pay special attention to the quality of heat transfer oil. If too much moisture or other impurities are mixed into the heat transfer oil, the fuel injection may occur when the temperature of the heat transfer oil is slightly higher, which may waste oil on the one hand and may cause a fire on the other hand.

   3. The oil temperature in the boiler body is very high, but the temperature of the heat equipment is not enough, so that the heat supply is insufficient. In order to meet the heating demand, some enterprises blindly increase the temperature of the oil outlet, local overheating occurs, and the oil is coked, resulting in a burst. Therefore, we must ensure that the temperature of the oil outlet can not exceed its maximum limit during use, to ensure the flow rate of oil in the pipe, to avoid the occurrence of pipe burst.

   4, the boiler itself, such as pipe welding is not strict, weld seams and so on. The heat transfer oil will leak, causing a fire in an open flame.

   5. Finally, in addition to the above problems, the furnace workers are also particularly important, which can be said to be the main heart. We must choose to participate in formal training, and the driver of the operating certificate is required to work. Do a good job in cleaning, inspection and warranty work of the heat-conducting oil furnace to prevent all kinds of sudden occurrences and ensure safe production and efficient production.
