How to stop the natural gas thermal oil wall-hung boiler when using it

The thermal oil boiler diesel burner is mainly used for the processing, storage and transportation of heating crude oil and mineral oil. The oil refinery uses heat transfer oil to preheat the cold material, which has been successfully used in the heating solvent and extractant evaporator in the lubricating oil production process. Do you know what should be paid attention to when the diesel burner of the gas heat transfer oil boiler is turned off? 1. Emergency shutdown method of gas heat conduction oil furnace and light oil burner If the furnace is stopped in an emergency, the burner should be shut down quickly, and the burner should be moved along the burner reaming axis to form a natural ventilation state between the furnace and the chimney. Heat storage and distribution in the furnace, so that the heat transfer oil is naturally cooled to prevent overheating. 2. Normal stop (1) Gradually reduce the temperature, turn off the burner, and stop burning; (2) When the hot oil temperature drops below 70°C, stop the operation of the hot oil circulating pump (see the operating rules of the water pump); (3) Turn off the main power and make a record of the switch. 3. During the inspection, check whether there is any leakage around the light oil burner of the gas heat transfer oil furnace. Sufficient oil-electric fire-fighting equipment should be equipped nearby. Do not use water as a fire extinguishing agent. Clean technology If your heat conduction oil furnace light oil burner has been used for a long time or the selected heat conduction oil is not good or used improperly, coking and carbon deposits will block the pipes and heating surfaces, reduce heat transfer efficiency, increase energy consumption, and finally it will be difficult Meet production needs. Thermal oil boiler diesel combustion engine oil carbon scale cleaning technology First of all, the thermal oil boiler diesel burner is being used quickly. Heat transfer oil boiler diesel burner (heat medium boiler diesel burner) is a kind of organic heat medium oil used as heat transfer muon boiler diesel burner. Because of the safety and efficiency of petroleum, chemical industry, printing and dyeing, food, etc., it is under lower working pressure A higher working temperature can be obtained. 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: The condensation of heat-conducting oil can easily coke the heat transfer area of ​​the boiler diesel burner. Heat transfer oil is prone to thermal cracking and polymerization chemical reaction 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. Problem 2: Coke fouling in the heat transfer area will increase energy consumption and cause fire accidents. The accumulation of oil coke scale on the heat transfer tube wall of the heat transfer oil boiler diesel combustion engine not only greatly reduces the heat transfer efficiency, increases the fuel cost, but also affects the temperature of the downstream 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. Matters needing attention 1. For the oil and gas heat carrier boiler diesel burner using heat transfer oil as the heat carrier, the system should be equipped with an expansion tank, a 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 during the running phase, and start ignition and heating after running for half an hour. When using for the first time, the temperature should rise slowly, about 20℃ per hour. When the temperature rises to 180~200℃, the temperature should be kept for a period of time before normal use. 3. When using, check carefully and strictly prevent the leakage of water, acid, alkali and low boiling point substances into the use system. The system should be equipped with a filter device to prevent all kinds of debris from entering and to ensure the purity of the oil. 4. After six months of use, oil analysis should be performed. If poor heat transfer or other abnormal conditions are found after long-term use, the oil should be analyzed, added or replaced according to the analysis results. Standard dosage: basic carbon must not be greater than 1.0%, acid value must not be greater than 0.5mgK(OH)/g, ignition point change must not be less than 20%, viscosity change must not be greater than 10%, and the new oil should be replaced. 5. In order to ensure the normal service life and heat conduction effect of heat transfer oil, it is strictly prohibited to use over temperature. !
