1.
Avoid heat conduction oil coking heat conduction oil use in operating temperature more than the highest temperature, the coking phenomenon, in the oil guide pipe wall as the coking layer thickening, guide oil pipe wall temperature on the high side and prompted adhesion coking, further improve the thickening of the tube wall temperature unceasingly, along with the thickening of the wall heat transfer performance deterioration, explosion accident may occur at any time.
Therefore, strictly control the heat transfer fluid outlet temperature shall not exceed the highest use temperature of the heat conduction oil, heat carrier in the highest temperature should be less than allowed temperature of oil film.
2.
Avoid heat conduction oil oxidation due to heat conduction oil under the condition of high temperature operation is easy to happen in the heat carrier oxidation reaction, causing deterioration of heat conducting oil metamorphism, so often set high temperature expansion slots for nitrogen protection, to ensure that the heat transfer fluid system closed, avoid heat conduction oil is exposed to air, prolong the service life of heat conduction oil.
3.
Regular screening leak strengthen site monitoring, to ensure that heat carrier system in good condition does not leak, regular screening equipment corrosion leakage situation, found that leakage and repair.
Heat carrier system, therefore, reasonable design, use of test equipment regularly wall thickness and compression strength, and on the equipment and pipeline with pressure gauge and relief valve and vent pipe.
