The use method and precautions of thermal oil electric heater
1. The operator of the heat-conducting oil electric heater should be trained in the knowledge of heat-conducting oil electric heater, and be evaluated and issued by the local boiler safety supervision agency.
2. Units using thermal oil electric heaters must formulate operating procedures for thermal oil electric heaters. The operating procedures shall include the operation methods and precautions for starting, running, shutting down the furnace, and emergency shutting down the heat-conducting oil electric heater. The operator must operate in accordance with the operating procedures.
3. Heat preservation measures should be taken for the pipes within the range of the heat-conducting oil electric heater, but the flange joints should not be covered.
4. During the heating process of the heat-conducting oil electric heater, the exhaust valve of the expansion tank should be opened to exhaust air, water and organic heat carrier mixed steam before it can enter normal operation.
5. The organic heat carrier must be dehydrated before use. Different organic heat carriers should not be mixed. When mixing is required, the organic heat carrier production unit shall provide the mixing conditions and requirements before mixing.
6. The organic heat carrier in use should be analyzed every year for its residual carbon, acid value, viscosity, and flash point. When two analyses are unqualified or the content of the decomposition component of the heat carrier exceeds 10%, the heat carrier should be replaced or The heat carrier is regenerated.
7. The heating surface of the heat-conducting oil electric heater should be inspected and cleaned regularly, and the inspection and cleaning conditions should be stored in the boiler technical file.
8. After the heat-conducting oil electric heater is installed or heavily repaired, the user and the installation or repair unit should conduct a hydraulic test of 1.5 times the working pressure before it is put into operation. During the hydraulic test and air tightness test, the local boiler safety supervision agency should send people to participate.
9. The boiler room should have effective fire prevention and extinguishing measures.
