Heat transfer oil is a flammable organic substance that poses risks of ignition and explosion. The common risks associated with heat transfer oil are as follows: 1. If water enters the gas phase, expansion due to rapid temperature increase can lead to an explosion. 2. The heat transfer oil deteriorates too rapidly; insoluble carbon particles form, causing seal damage and resulting in leaks. 3. The leaked heat transfer oil enters the insulation layer of the pipeline, where it gradually oxidizes to form components with a low auto-ignition point, which can lead to spontaneous ignition. 4. In a gas-phase system, the leaked heat transfer oil will form mist; if it disperses into the air, it will inevitably catch fire or explode. 5. If the heat transfer oil leaks, it will burn violently in contact with oxidizers or catalysts, and even explode. 6. In the event of any leakage at the flange connections or pump seals, it must be addressed promptly to prevent ignition in the presence of an open flame. 7. Due to partial overheating in the heater pipelines, coking inside the pipes or overpressure can cause the furnace tubes to crack, leading to accidents. 8. The expansion tube groove comes into contact with air, and high-temperature oxidation leads to spontaneous combustion. Overall, heat transfer oil boiler systems operate at high temperatures and low pressures; compared to steam boilers which operate at high pressures, they are much safer:D
