Precautions in heating up the heat-conducting oil boiler diesel burner

The thermal oil boiler diesel burner refers to the boiler diesel burner heated by the thermal oil. Heat transfer oil, also known as organic heat carrier or heat medium oil, has been used as an intermediate heat transfer medium in industrial heat transfer processes for more than 50 years. The boiler diesel burner is developed based on the design concept of forced circulation. Generally, coal, petroleum, and natural gas are used as fuels, and heat transfer oil is used as a medium. The hot oil circulation pump is used to force the medium to circulate in the liquid phase. The heat energy is transferred to the heating equipment and then returned to the heating furnace for reheating. 1. The ignition and heating process of the thermal oil boiler diesel burner should strictly follow the heating curve (or the heating curve provided by the heat carrier furnace manufacturer). 2. When the temperature of the heat-conducting oil boiler diesel burner rises above 200°C, the equipment and the entire system should be thoroughly inspected, and all bolt joints should be tightened once to eliminate the leakage caused by thermal expansion. 3. Pay attention to the expansion of the thermal oil boiler diesel burner. When the temperature is lower than 100°C, it is about 6%. It is about 7% at 100~200℃, and about 7.5% at 200~300℃. If the liquid level of the expansion tank is too high, open the liquid pipe and put the heat carrier into the low water storage tank to prevent the heat carrier from overflowing from the high water tank and cause an accident. 4. The circulating pump must be started for ignition in the cold furnace of the thermal oil boiler diesel combustion engine. Before ignition in a cold northern area, the heat carrier and steam should be heated and melted, and then the circulation pump can be started. 5. The heat transfer oil boiler diesel combustion engine furnace evaporates water from the expansion tank in the expansion tube factory. Part of the gas is discharged from the vent tube, and the other part is condensed at the bottom of the tank. In order to prevent water from entering the circulation system again, it must be regular During the heating process, open the expansion tank at the bottom of the drain pipe to drain the condensed water. Clean technology If your heat transfer oil boiler diesel burner is used for a long time or the selected heat transfer oil is not good or improperly used, coking and carbon deposits will block the pipes and heating surfaces, reduce heat transfer efficiency and increase energy consumption, and it will be difficult to meet Production demand. Heat transfer oil boiler diesel combustion engine oil carbon scale cleaning technology First of all, the quick use of heat transfer oil boiler diesel burner The heat transfer oil boiler diesel burner (heat medium boiler diesel burner) is a kind of organic heat medium oil as heat transfer muon boiler diesel combustion Because of the safety and efficiency of petroleum, chemical, printing and dyeing, food, etc., the machine can obtain higher working temperature under lower working pressure. Chemical fiber, plastics, coatings, building materials and other industrial enterprises quickly spread and use. Problems existing in the use of heat-conducting oil boiler diesel burner Problem 1: Condensation of heat-conducting oil easily makes the heat transfer area of ​​boiler diesel burner coking heat-conducting oil prone to thermal cracking and polymerization chemical reactions after high temperature heating, which reduces oil quality. For example, the heat transfer oil gel is thick, the carbon residue and acid value exceed the standard, and the coke crystals precipitate and deposit, causing the coking 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. The accumulation of oil coke fouling on the heat transfer tube wall of the heat transfer oil boiler diesel burner not only greatly reduces the heat transfer efficiency, increases the fuel cost, but also affects the downstream The temperature of the production process. Severely lead to overheating of the heat transfer wall, cracks in the pipe wall, corrosion and pipeline explosion, and major safety accidents such as fire and casualties caused by heat conduction oil leakage. Heat transfer oil coke resistance and anti-scaling technology First of all, the deterioration of petroleum accelerates the carbon coking of boiler diesel burners. In the process of using heat transfer oil boiler diesel burners, the chemical components of heat transfer oil are prone to high-temperature oxidation, cracking decomposition and thermal condensation and other chemical reactions , Make the grease gel. The coke particles produced by polycondensation greatly increase the carbon residual value of the heat transfer oil and form coke 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. ! If you are interested in diesel combustion engines, please contact us for a quote!
