Prevention of heat-conducting oil boiler diesel burners against bumping accidents

1, cook the oil carefully (1) Start the oil cooking, because the oil temperature is lower and the viscosity is higher , So the oil flow rate is low, and the heat exchange coefficient between the oil and the metal pipe wall is very small, so the temperature must be increased and slow, otherwise it will cause local overheating. (2) When the high temperature of the thermal oil boiler diesel combustion engine reaches 90°C, stop heating for no less than 2 hours to allow the moisture in the thermal oil to flow out of the line, and pay special attention to the moisture in the oil and then begin to evaporate in large quantities. It will expand, so be careful not to let the oil and gas in the high fuel tank overflow outside the fuel tank and cause an accident. And pay close attention to whether there is air bubble blockage in the oil system. When there are bubbles in the pipeline, the inlet and outlet pressure of the oil pump drops immediately. At this time, as few bubbles as possible should be discharged. (3) When the circulation is normal, the oil can continue to be heated and boiled for a long time. The length of cooking oil depends on the amount of oil in the system and the water content in the oil. Generally, it takes 10 to tens of hours to cook oil. The heating rate of the diesel combustion engine oil of the domestic thermal oil boiler does not exceed 5-6℃ per minute. Set up a high expansion water tank to prevent hot oil accidents caused by expansion and overflow. The capacity of the oil loading system should be considered in the system design. The total capacity is 1.5, which should be placed on the top of the system to stabilize the operating pressure of the circulating system. Generally, the highest point system above 2 meters can be used, but it cannot be used in the heat transfer oil boiler diesel Burning machine. The volume of the low oil storage tank should be within 0.5 of the total load of the system. Clean technology If your heat transfer oil boiler diesel burner is used for a long time or the selected oil is not good or improperly used, coking and carbon deposits will block the pipes and heating surfaces, reduce heat transfer efficiency, increase energy consumption, and finally difficult to meet production Needs. Hot oil boiler diesel combustion engine oil stain cleaning technology Heat transfer oil boiler diesel combustion engine is a boiler diesel combustion engine that uses organic heat transfer medium oil as the heat transfer medium. It can obtain higher working temperature under lower working pressure and quickly Promote the application in petroleum, chemical industry, printing and dyeing. , Food, chemical fiber, plastics, coatings, building materials and other industrial enterprises because of its safety and efficiency. Problems in the use of heat transfer oil boiler diesel burners. Problem 1: The condensation of heat transfer oil easily makes the carbon coking heat transfer oil in the heat transfer zone of the boiler diesel burner easy to undergo thermal cracking and polymerization chemical reactions after high temperature heating, resulting in a decrease in oil quality . If the hot oil is gelled, it will thicken, the residual carbon and acid value will exceed the limit, and the coke will precipitate and precipitate, which will cause the coke oil carbon scale in the heat transfer zone of the boiler diesel burner. Question 2: Coke fouling in the heat transfer area will increase energy consumption and cause fire accidents. After petroleum coke fouling accumulates on the heat transfer tube wall of the heat transfer oil boiler diesel burner, not only the heat transfer efficiency is greatly reduced, the fuel cost increases, but also downstream production The process temperature is also affected. In severe cases, it may cause local overheating of the heat transfer wall, rupture of the pipe wall, corrosion and explosion, and cause fire, casualties and other major safety accidents caused by the leakage of heat transfer oil. Heat transfer oil coke scale inhibition control technology 1. Oil degradation accelerates boiler diesel burner carbon coke. In the process of using heat transfer oil boiler diesel burner, the chemical composition of heat transfer oil is prone to high temperature oxidation, cracking decomposition, thermal condensation, etc. due to heat The chemical reaction that takes place gelatinizes the grease. The carbon particles produced by polycondensation greatly increase the residual carbon value of the heat transfer oil and form carbon scale on the heat transfer surface. The scale of oil and carbon endangers the safe operation of boiler diesel burners. The carbon scale formed by the thermal oil product oil coke not only greatly reduces the heat transfer efficiency of the thermal oil boiler diesel burner, but also greatly increases the energy consumption cost, and it also leads to diesel combustion in the thermal oil boiler. The machine-corrosive metal corrodes and scales at high temperatures, the furnace tube metal is damaged by cracks or corroded holes, and the furnace tube can be burned in severe cases. The leakage of heat transfer oil may cause major accidents such as fire and human life. Matters needing attention 1. For the oil and gas heat carrier boiler diesel burner with heat transfer oil as the heat carrier, the system should be equipped with an expansion tank, water storage tank, safety components, measuring instruments and control devices. 2. When the heat transfer oil is put into use, start the circulating oil pump at the beginning of the operation. After running for half an hour, start ignition and heating. The temperature should be raised slowly during the first use, and the temperature should be about 20℃ per hour. When the temperature rises to 180~200℃, and keep it warm for a period of time, it can be used normally. 3. Check carefully during use to prevent leakage of water, acid, alkali and low boiling point substances into the use system. The system should be equipped with a filtering device to prevent all kinds of debris from entering and to ensure the purity of the oil. 4. After half a year of use, the oil should be analyzed once. After long-term use, if poor heat transfer or other abnormal conditions are found, the oil should be analyzed, added or replaced according to the analysis results. Judgment criteria: basic carbon is not more than 1.0%, acid value is not more than 0.5mgk(OH)/g, ignition point change is not less than 20%, viscosity change is not more than 10%, one of which exceeds the standard should be replaced with new oil. 5. In order to ensure the normal service life and heat conduction effect of heat transfer oil, it is strictly prohibited to use it under over temperature. The design and installation of the heating system of the heat-conducting oil burner light oil burner should strictly follow the hot oil burner design regulations formulated by the relevant state departments to ensure the safe operation of the system.
