Heating process of high-temperature heat transfer oil

Thread Content

Heating process of high-temperature heat transfer oil Heat transfer oil is one of the best materials for high-temperature heating; as the name implies, high-temperature heating requires a process of temperature increase. The temperature increase mainly involves gradually raising the operating temperature of the heat transfer oil to the process temperature within the allowable range, in order to meet the production requirements. So let’s take a look at what needs to be considered: 1: The temperature increase must occur after the oil has been boiled to remove water from it. As gases are continuously removed from the heat transfer oil system and the oil is continuously replenished, the operating pressure of the hot oil circulation pump as well as the pressure difference between the inlet and outlet of the heating furnace, along with the flow rate of the heat transfer oil, will tend to become normal and stable. Only under these conditions can the operating temperature of the heat transfer oil be increased gradually. 　　2: The initial heating rate should not be too fast; it should follow the specified heating curve (with a heating rate of about 20°C per hour). 　　3: During the heating process, it is necessary to conduct regular inspections to ensure that all relevant equipment and their associated process systems are operating properly, and to check whether their vibration, noise levels, and lubrication conditions are within normal ranges. 　　4: During the heating process, a thorough inspection should be carried out on all relevant equipment as well as their pipes and valves to ensure there are no leaks. 　　5: During the heating process, a thorough inspection should be carried out to ensure that the supports of all relevant equipment, process systems, and pipelines are stable. 　　6: During the heating process, a thorough inspection should be carried out on the thermal expansion of all relevant equipment and their pipelines. 　　7: During the heating process, it is necessary to continuously check whether various process parameters such as temperature, temperature difference, pressure, pressure difference, and flow rate are within normal and stable ranges. 　　8: The temperature difference should not be too large, and the pressure difference should not be too small. 　　9: During the heating process, a thorough inspection should be carried out to ensure that all electrical instruments and their control and alarm devices are functioning correctly. 　　10: During the heating process, records of the heating furnace’s debugging and operation should be kept at all times.
