Technical Details & Test Data
- Key points for safe use of AB series heat transfer oil
1. According to the technical requirements of heat conduction, select correctly, and strictly follow the regulations in the "Safety Technical Regulations for Organic Heat Carrier Heating Furnace".
2. Do not infiltrate water, acid, alkali and other boiling point impurities during use, and install a filter device to prevent mechanical debris from entering to ensure the purity of the oil.
3. In the heating circulation system, a volume expansion tank and storage tank equivalent to more than 30% of the oil volume must be installed to ensure that the high temperature does not directly contact the air. Make the equipment operate safely.
4. Different types of heat transfer oil cannot be mixed at will. The old heat transfer oil equipment must be cleaned of debris in the wall before use. When replacing the heat transfer oil, the heat transfer oil system must also be thoroughly cleaned before adding new oil. Otherwise it will affect the heat transfer efficiency and the service life of the heat transfer oil.
5. The usage method of AB series heat transfer oil is basically the same as other types of heat transfer oil. Before ignition, the circulating pump should be started and run for half an hour. The temperature should be increased slowly at first, about 20ºC per hour. When it rises to 105ºC-150ºC, the temperature should be increased slowly, about 0-5ºC per hour. To exhaust and remove water. When the temperature rises to about 250ºC, slowly increase the temperature, 5-10ºC per hour to remove the trace low boiling point components, and then it can be put into normal operation.
6. Under normal circumstances, conduct an oil product analysis on the heat transfer oil every six months. If the residual carbon is greater than 1.5%, the acid value is greater than 0.5mgKOH/g, the flash point drops by more than 20%, and the viscosity changes by more than 15%, any one of these four items is unqualified, and replacement of new oil or regeneration treatment must be considered.
Heat transfer oil is used for heat transfer. The key is its own stability. For example, changes in viscosity and flash point can show that the structure of the oil itself has changed. Stable; the flash point becomes higher, the viscosity increases, and the oil is cracked and polymerized at high temperature to form high boiling substances, causing carbon deposits on the inner wall of the system, causing heat to be difficult to transfer, increasing coal consumption, and so on.
7. The nominal pressure of the flange and the valve should be 1.6MPa, and the connection between the valve and the dust blue should use the GB-203-76 oil-resistant and high-temperature asbestos rubber sheet of the Building Materials Department as a gasket.
8. It is strictly forbidden to over-temperature during operation, so that the temperature is controlled below the highest safe use temperature (temperature automatic brake can be configured) to ensure the safe use and correct service life of the heat transfer oil.
9. In order to prevent local overheating and cause coking, the heat transfer oil should maintain a turbulent state when running in the pipeline. The Reynolds number should be between 5000-20000, and the flow velocity should be between 1.5-3 m/s.
10. In case of a sudden power failure during operation, immediately open the furnace door, close the hot oil furnace valve, and open the lower tank valve to allow the hot oil from the furnace tube to flow to the lower tank, so that the cold oil from the expansion tank flows into the furnace tube , In order to protect the furnace tube and the use of heat transfer oil.
11. The fire protection requirements of the heating furnace room shall be in accordance with the requirements of the building design code, and reasonable fire protection equipment shall be provided in the hot oil furnace installation area. Water is strictly prohibited.The harm of coking and carbon formation in heat conduction oil furnace system
The coking and carbon generated during the use of heat transfer oil will form a thermal insulation layer on the one hand, but the heat transfer effect will decrease, the exhaust gas temperature will rise, and the fuel consumption will increase; on the other hand, due to the temperature requirements of the production process, the heating furnace tube wall The temperature difference will rise sharply. If the temperature difference between the inside and outside of the furnace tube increases to 600-700ºC, it will easily burn through the furnace tube and cause a fire safety accident. According to the Fourier heat transfer equation of fluid thermodynamics, the influence of different coking and carbon Baidu on the temperature difference of the heating furnace tube is calculated, as shown in the following table:Coking carbon thickness Mm 0 2 4 6 8 10 12 Outer wall temperature of furnace tube ºC 373 423 473 523 576 623 673 Inner wall temperature of furnace tube ºC 330 330 330 330 330 330 330 Temperature in the furnace tube ºC 43 93 143 193 243 293 343 The company has a professional heat transfer oil after-sales service team, including guidance on the correct use of heat transfer oil, oil product testing and judgment.
