The preventive measures for thermal oil fires mainly include the following aspects:

1、 Ensure that equipment and materials are qualified

1. Use qualified thermal oil:

Choose a heat transfer oil with high heat transfer efficiency, wide applicable temperature range, good thermal stability, high flash point, high self ignition point, good fluidity, and low carbon residue.

Regularly sample and analyze the thermal oil, timely grasp the quality changes of the oil, and regularly replenish new thermal oil to maintain its stable residual carbon content.

2. Choose high-quality equipment and materials:

Ensure that the quality of the thermal oil boiler and its accessories (such as valves, pipelines, etc.) meets relevant standards, and conduct regular pressure tests.

Use insulation materials that are not easily wetted, such as aluminum silicate and alkali silicate insulation materials, and avoid using rock wool insulation materials.

2、 Strengthen daily management and operations

1. Professional training for operators:

Operators should receive professional training to understand the working principle, safety operating procedures, and emergency response measures of thermal oil boilers.

Operators must hold relevant operation certificates and strictly comply with the "Boiler Safety Technical Supervision Regulations".

2. Regular maintenance and upkeep:

Regularly inspect and maintain the thermal oil boiler and its accessories, including maintenance and repair of oil leaks, oil pumps, oil pipes, and other components.

Clean the burner, remove carbon deposits and dirt, and ensure normal combustion.

3. Reasonably set and control parameters:

Reasonably set the temperature of the thermal oil and do not exceed the tolerance temperature of the equipment.

Control the flow rate of the heat transfer oil to ensure it is not lower than the specified value, in order to prevent accidents such as residual carbon, blockage of pipe diameter, and overheating of pipe walls.

3、 Install safety equipment and alarm devices

1. Install fire alarm device:

Install fire alarm devices in the heat transfer oil boiler room, and in the event of a fire, promptly sound the alarm and take corresponding measures.

2. Configure fire extinguishing equipment:

According to the fire situation, choose appropriate firefighting equipment for extinguishing the fire, such as dry powder fire extinguishers, carbon dioxide fire extinguishers, etc.

3. Set up emergency shutdown device:

Install an emergency shut-off device on the heat transfer oil supply pipeline to quickly cut off the heat transfer oil supply in case of a fire.

4、 Dealing with unexpected situations

1. Develop emergency plans:

Develop an emergency plan for heat transfer oil boiler fires, clarify emergency response procedures and responsible persons.

Regularly conduct emergency drills to improve the emergency response capabilities of operators.

2. Handling leakage accidents:

When a thermal oil leakage accident occurs, the power supply of the thermal oil furnace should be immediately cut off to reduce the amount of thermal oil leakage.

Use fire extinguishing equipment or steam to cool down and flame retardant the smoldering area, then slowly remove the insulation layer, repair the leakage point, and replace the insulation material.

In summary, the prevention measures for thermal oil fires involve multiple aspects such as equipment and material selection, daily management and operation, installation of safety equipment and alarm devices, and response to emergencies. By taking these measures, the risk of thermal oil fires can be effectively reduced, ensuring the safety of the production environment and the safety of personnel's lives and property.
