HTF various grades of oil due to the use of serious dirt appear, charring dirt, coke dirt. [Operation] cleaning process: pre-wash discharge of used oil → → washing → washing ① → ② → washing ③ → washing add new oil → dehydration → normal operation (1) Emissions of used oil: use heating system, oil heating to 70-80 ℃, hot exhaust system within all HTF, after the discharge is completed, according to the conditions, with compressed air purge system is not drained the remaining HTF. (2) Pre-wash: the cleaning cycle of special agents by 12 percent of the total measure dissolved, the heating system in any part of the investment system, water and electricity to the system NOTE Manchu Profile furnace and heated to 60 ℃ ± 5 ℃, switch System-related valves in all parts of the system are cleaned separately. Three hours later, turn the system on all low drain valve, exhaust system water. (3) Cleaning: cleaning special agents after dissolution of 5 to 8% of the total measurement cycle by, in any part of the heating system into the electric heating furnace system, to the system later filled with water, heated to 90 ℃ ± cleaning agents 5 ℃. Valve switching system, so that all parts of the system are cleaned Jieke valve switch once per hour is appropriate. The cleaning time of not less than 24 hours. (4) water ①: the system fill with water, the water temperature rose to 90 ℃ ± 5 ℃, the switching system associated valves in all parts of the system are cleaned separately. Rinsing the system, three hours later, open all low drain valve, exhaust system in the water system. We generally use oil furnace capacity than the actual amount of 10% of steam on the line. And unit planning and boiler oil boiler selection is very important, we selected oil boiler must pay attention to diet coal in the region. In addition, we have to choose the new, high thermal efficiency, high degree of automation of oil boiler. When the oil boiler normal operation of thermal electric furnace, should be sufficient to launch the emission of air, water vapor and light components. In the operation should be kept high enough flow HTF electric furnace manufacturing, avoid outages stop the pump, in order to avoid overheating of thermal oil coke or carbon, the filter should be regularly finishing. Used oil boiler should be designated national manufacturers of qualified products. Equipment oil boiler heating system manufacturer shall complete units or pointing device, and fit the rules of acceptable quality. Oil boiler heating system and safety equipment should be completely intact, over-temperature, over-voltage protection device should be active and reliable. On the use of oil boiler, the how to achieve a more efficient use of its function has always been our users are most concerned questions, along with the majority of the producers of this is we have been trying in the direction of the electric furnace electric furnace design _ _ Entertainment provided by the Hebei Arts Boiler boiler limited liability company.
