What are the precautions for using heat conduction oil furnace?

(1) When the heat transfer oil boiler diesel burner is insulated, the heat transfer oil circulation pump should not be turned off until the furnace temperature Down to the specified range. Every time the furnace is turned on, the circulation pump should be turned on first. If the power is suddenly cut off or the circulation system fails, ventilation and cooling should be used. Also need to use cold heat transfer oil instead. (2) Correctly select the heating furnace of the heat-conducting oil boiler diesel burner (generally the nominal capacity 1. Choose Ⅲ 5 times) to avoid a large overload ratio and uneconomic phenomenon. The selection of the heating capacity of the heating furnace is not only related to the safety and life of the heating furnace, but also affects the service life and production cost of the heat transfer oil. (3) Choose heat conduction oil for heat conduction oil furnace and light oil burner, which should have good thermal stability, oxidation resistance and coking resistance. When buying heat transfer oil for oil furnaces, be careful not to choose dark odor and color of heat transfer oil. The service life of heat transfer oil is measured by four indicators: carbon residue, acid value, flash point and viscosity. An oil test is conducted every six months to control the quality of heat transfer oil. Find out the problem and replace the heat transfer oil in time, find out the cause of heat transfer oil deterioration and preventive measures as soon as possible. At the same time, it is necessary to strictly control different amounts of heat transfer oil not to mix. (4) Use heat-conducting oil furnace light oil burner in strict accordance with operating procedures to avoid rapid heating (the heating rate should be controlled at 10-40℃, h), over-temperature and over-pressure, and emergency measures should be taken to stop the furnace quickly and decisively, and observe at any time The oil level and temperature of the expansion tank. If there is a shortage of oil, it should be refilled in time. Prevent air and water from entering the oil circulation system of the light oil burner of the heat transfer oil furnace. Since the direct contact of high-temperature heat transfer oil with air will accelerate the oxidation rate (the oxidation rate will increase by 2 times when the temperature rises by l0°C) to prevent the high-temperature oil from directly contacting the air. A better method is to seal the upper space of the expansion tank with nitrogen. The protective gas film is formed under unconditional nitrogen sealing conditions. Generally speaking, the heat transfer oil temperature of the high water tank should not exceed 60℃, and the high water tank should not be directly connected in series in the circulation system. (5) Improve the thermal efficiency of the heat-conducting oil boiler diesel burner, and timely remove the dirt on the inner wall of the furnace and the wall of the coil to ensure a good heat transfer effect. At the same time, better quality coal should be used as much as possible so that the heat generated by burning coal can be converted into hot oil in a timely and comprehensive manner. (6) The design of the full oil circulation system of the thermal oil boiler diesel combustion engine should be comfortable. Minimize elbows and valves. Choose a high-efficiency circulating pump. Clean the filter in time to ensure that the flow rate of the high-temperature heat transfer oil is not less than 2 m/s. Clean technology If your boiler diesel combustion engine has been used for a long time or the selected hot oil is not good or used improperly, coking and carbon deposits will block the pipeline and heating surface, reduce heat transfer efficiency, increase energy consumption, and finally it is difficult to meet the production requirements. need. Heat transfer oil boiler diesel combustion engine oil stain cleaning technology Heat transfer oil boiler diesel burner is rapidly using heat transfer oil boiler diesel burner (heat medium boiler diesel burner) is a boiler diesel burner that uses organic heat medium oil as the heat transfer medium. High working temperature can be obtained under low working pressure, and it can be quickly promoted to be used in petroleum, chemical, 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 thermal oil boiler diesel burners. Problem 1: The condensation of heat transfer oil easily causes the thermal cracking and polymerization chemical reaction of the carbon coking heat transfer oil in the heat transfer zone of the boiler diesel burner to cause thermal cracking and polymerization chemical reactions after high temperature heating, resulting in a decline 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. 2. Carbon fouling endangers the safe operation of boiler diesel burners. The carbon fouling 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. It will also cause the thermal oil boiler diesel The metal corroded by the burner corrodes and scales at high temperatures. The metal of the furnace tube is damaged by cracks or corroded holes. In severe cases, the furnace tube can be burned. The leakage of heat transfer oil may cause major accidents such as fire and human life. !
