1. Operators of electric heating and heat transfer oil furnaces should receive training on knowledge related to electric heating and heat transfer oil furnaces, and be assessed and certified by local boiler safety supervision agencies.

2. Units using electric heating heat transfer oil furnaces must develop operating procedures for electric heating heat transfer oil furnaces. The operating procedures should include the start-up, operation, shutdown, emergency shutdown and other operating methods and precautions for the electric heating heat transfer oil furnace. Operators must operate according to the operating procedures.

3. Insulation measures should be taken for pipelines within the range of electric heating and thermal oil furnaces, but covering measures should not be used for flange connections.

During the ignition and pressure boosting process of the electric heating heat transfer oil furnace, the exhaust valve on the boiler should be opened multiple times to exhaust the mixed steam of air, water, and organic heat carriers. For gas-phase furnaces, when the temperature and pressure of the organic heat carrier match the corresponding relationship, the exhaust should be stopped and normal operation should be resumed.

5. Organic heat carriers must undergo dehydration before use. Different organic heat carriers should not be mixed for use. When mixed use is required, the organic heat carrier production unit should provide the mixing conditions and requirements before mixing.

6. The residual carbon, acid value, viscosity, and flash point of the organic heat carrier in use should be analyzed annually. When two analyses fail or the content of decomposed components in the heat carrier exceeds 10%, the heat carrier should be replaced or regenerated.

7. The heating surface of the electric heating thermal oil furnace should be inspected and cleaned regularly, and the inspection and cleaning results should be recorded in the boiler technical file.

8. After the installation or major repair of the electric heating heat transfer oil furnace, a hydraulic test at times the working pressure should be conducted by the user unit and the installation or repair unit before putting it into operation. For gas-phase furnaces, an air tightness test should be conducted according to Article 15. Only after passing the qualification can it be put into operation. During hydraulic and air tightness tests, the local boiler safety supervision agency should send personnel to participate.

9. The boiler room should have effective fire prevention and extinguishing measures. Diphenyl ether manufacturer
