Maintenance of heat-conducting oil boiler diesel burner

The heat transfer oil boiler diesel burner is the general term for a type of boiler diesel burner that uses heat transfer oil to conduct heat to the heating equipment. It uses coal, oil, and gas as fuel for heating, and uses a hot oil circulating oil pump to force the medium to circulate in the liquid phase. In the daily use process, it is best for operators to carry out targeted maintenance work according to different fuel types, so that the boiler diesel combustion engine can be used for a longer time. So let's briefly explain below. The working characteristics of the heat transfer oil boiler diesel burner Compared with the traditional heat transfer medium water and steam, the heat transfer oil boiler diesel burner has the following characteristics: It can obtain a high operating temperature under almost normal pressure. That is, the operating pressure and safety requirements of the high-temperature heating system can be greatly reduced, and the reliability of the system and equipment can be improved; it can meet the process requirements of heating and cooling at different temperatures in a wider temperature range, or use the same type in the same system The heat transfer oil realizes the process requirements of high temperature heating and low temperature cooling at the same time. That is, the complexity of the system and operation can be reduced; the water treatment system and equipment are omitted, the thermal efficiency of the system is improved, and the maintenance workload of the equipment and pipelines is reduced. That is, the initial investment and operating costs of the heating system can be reduced; in the case of system leakage caused by the accident, the heat transfer oil may burn when it meets the open flame. This is the problem of the heat transfer oil system compared with the water vapor system. But under the condition of no leakage, because the heat transfer oil system works under low pressure conditions, its operational safety is higher than that of water and steam systems. Compared with another type of high temperature heat transfer medium molten salt, the heat transfer oil furnace light oil burner has an absolute advantage over the heat transfer oil in terms of the price and service life of the heat transfer medium when the operating temperature is above 400℃. In other respects are at a significant disadvantage, especially in the complexity of system operation. Why does the heat-conducting oil boiler diesel burner need to be maintained? After the heat-conducting oil in use deteriorates or is seriously polluted, it is often easy to coke and deposit in the pipes of the boiler diesel burner and heat transfer system, and the heat-conducting oil with higher viscosity is easy to adhere to A thick oil film is formed on the tube wall of the boiler diesel burner, which not only reduces the circulation flow of the system, easily causes the overheating of the heat transfer oil, but also accelerates the deterioration of the oil, deteriorates heat transfer, affects heat exchange, wastes fuel, and causes serious coking and accumulation. The charcoal can even burn the furnace tube, causing a fire accident and affecting safety. Therefore, when the residual carbon, viscosity, and acid value of the heat transfer oil exceed the standard, it should be replaced in time. For the more serious deterioration, especially the carbon residue, high viscosity, and more viscous residual oil adhered to the furnace tube and system pipeline, or even coking, the entire heat transfer oil boiler diesel should be burned when the oil is changed. The machine and system are cleaned as necessary. The cleaning scope should include: boiler diesel burner, circulation system, expansion tank and oil storage tank, etc. Some impurities will also have a stimulating effect, accelerate the rate of deterioration of newly refueled products, shorten the service life, and cause significant economic losses. Therefore, timely chemical cleaning of the boiler diesel burner and circulation system whose heat transfer oil has been deteriorated or seriously polluted is a serious measure to ensure the safety, energy saving, and economic operation of the heat transfer oil boiler diesel burner. Daily maintenance of the gas heat conduction oil boiler diesel combustion engine 1. Remember to check regularly. First of all, we must regularly check the various parts of the gas heat conduction oil boiler diesel combustion engine to see if there is any looseness. In many cases, if you do not pay attention, there will be loose parts. There will be safety hazards when you continue to use it, and you can continue to use it only after it is maintained, so that no other problems will occur. 2. Keep the interior clean and clean. When we are not using the boiler diesel burner, we must first release all the heat transfer oil inside, because when there is oil in it, the quality will change, and it will also be affected if a leakage accident occurs. The surrounding environment is sanitary, so after all the oil is discharged, the inside of the boiler diesel burner must be cleaned to keep the inside clean to avoid other impurities from appearing inside. 3. Check for leaks. Normally, the inner wall of the heating surface of the high-performance gas heat conduction oil boiler diesel combustion engine should be decoked at least once a year. At the same time, the entire heating system can be cleaned together. The oil storage pipeline valve shall be checked for leakage, the loose bolts shall be tightened in time and the sealing packing shall be replaced in order to continue working without knowing it if there is a leakage. Maintenance of oil-fired heat-conducting oil boiler and diesel burner 1.

The heat transfer oil in the diesel burner of the electric heating heat transfer oil boiler should not exceed the maximum allowable temperature. The quality of the heat transfer oil strictly controls the performance indicators of the organic heat carrier. The exhaust valve should be opened during the initial start of the organic heat carrier furnace to clear the air, water and the organic heat carrier mixed steam in the diesel burner of the electric heating heat transfer oil boiler. Generally, after half a year of use, the heat transfer oil is sampled and tested every 3 to 6 months, and different oils should not be mixed. 3. Electric heating heat transfer oil boiler diesel combustion engine boiler diesel combustion engine should always check the temperature measuring instrument and perform regular measurement to prevent the increase of the thermal resistance of the temperature measuring node, which may cause incorrect operation of the temperature. 4. The installation of the circulation pipeline should facilitate the removal of gas in the pipeline. If the circulation pipeline leaks, it should be stopped in time and repaired before use. 5. When it is found that the oil temperature is difficult to rise during the operation of the diesel burner of the electric heating heat transfer oil boiler, check whether the pipeline is unblocked, whether the valve is wrong, whether the filter is blocked, etc., and it can be used after removing it. The device should be removed and washed regularly. 6. The user should customize detailed operating procedures and regular maintenance and repair systems, and the operator should be very familiar with and master the essentials of this equipment. 7. Always check the electric heating tube contacts, fuses, instruments, electric contact pressure gauges and relays. 8. Since the electric heating heat conduction oil boiler diesel combustion engine uses precision instruments, severe vibration is strictly prohibited during transportation and installation. Do a good job in the maintenance and maintenance of the diesel burner of the electric heating heat transfer oil boiler, which can extend the life of the equipment and maximize its working efficiency, so that the entire production process can operate safely and stably. 9. After long-term use, the wiring must be reliable after replacing the electric heating element, and the heater should be tested for leakage to prevent the leakage of heat transfer oil, the contact of wires, and the fire causing fire accidents. Maintenance of coal-fired heat transfer oil boiler diesel burner 1. Maintenance of safety accessories for coal-fired heat transfer oil boiler light oil burner (1) The pressure gauge in the coal-fired heat transfer oil burner light oil burner should be checked daily to see if it is under pressure The pointers in the watch are beating or the pointers are not moving, and whether the surface is clear and recognizable. (2) The level gauges and thermometers in the boiler diesel combustion engine should also be checked every day, mainly to see whether they are legible, and whether their display is accurate and correct. In addition, whether there is dust or dirt in its interior or display. Also, if necessary, check and proofread work should be carried out. 2. Maintenance of the main body of the light oil burner of the coal-fired heat-conducting oil furnace (1) Decoking the inner wall of the heating surface of the light-oil burner of the coal-fired heat-conducting oil furnace, and, at the same time, should be combined with the entire pipeline and heating system In this way, it can be comprehensive and thorough, without any omissions. (2) If it needs to be out of service for a long time, then after the furnace body is completely cooled, all the heat load should be put into the storage tank, and then the blowdown valve and the vent valve should be closed, so that its good performance can be achieved. maintenance. 3. Maintenance of auxiliary equipment and pipelines of coal-fired heat-conducting oil furnace light oil burners (1) Check the pipeline valves of coal-fired heat-conducting oil furnace light oil burners for leaks and other problems, as well as the insulation layer on the pipeline, Is there any damage? (2) Check all the bolts in the boiler diesel burner to see if they are loose, and if any, they should be tightened in time. In addition, check the sealing packing for any problems. And, whether the temperature of the expansion tank in the boiler diesel burner is within the specified range. In addition, the filter should also be checked to see if there are any problems such as clogging. If any, it should be cleared and cleaned in time. Precautions for the use of heat-conducting oil boiler diesel burner 1. The leakage of flanges, valves and other connecting parts or seals in the system has not been solved in time and encountered open flames. 2. If the heat transfer oil leaks into the heated material and mixes with the oxidant or active catalyst in the material, it will burn violently. 3. The temperature in the high-position tank is too high, and the heat-conducting oil is exposed to oxygen through the exhaust pipe to oxidize and cause spontaneous combustion. 4. If moisture enters the gas-phase heat transfer oil system, its volume will expand rapidly and cause an explosion; or the leaked heat transfer oil in the system will form an aerosol and reach a certain concentration, which will also cause fire or explosion. 5. Adding new heat transfer oil does not remove moisture and volatiles in time. 6. Sudden power failure, the heat transfer oil stagnates in the furnace tube, causing overheating. 7. The improper use of the filter causes the coking and sticky substances to fail to filter out, and deposits on the bottom of the pot or the wall of the tube, causing overheating and overheating. After a long period of use, there may be some carbon deposits on the inner wall of the boiler diesel burner. If some companies do not pay attention to these, there may be certain safety risks. At the same time If the inner wall of the heat transfer oil burner and light oil burner equipment is not cleaned, it may reduce the heat transfer efficiency, and also affect the temperature of the industry. In severe cases, it may cause oil leakage and cause fires to cause casualties. Therefore, it needs to be performed regularly Clean. 1. Oil draining of the system: the circulating heat transfer oil will drain the heat transfer oil in the system at a temperature of 120±5℃. If you do not change the oil, please find a clean container for storage, and then remove the coke cleaning agent before preparing a proper amount of heat transfer oil. , When the oil in the heat transfer oil system is drained cleanly, the cleaning system is disconnected from the oil storage tank, and the connection between the high tank and the oil storage tank is also included. 2. Blowing residual oil step: connect the air compressor at the pressure gauge or other connectable places, increase the pressure of the system to 0.3-0.4MPa, and discharge instantly; repeat this operation until the residual oil is blown out , And the heat-conducting oil furnace light oil burner, circulation pump and other heat exchangers form a cleaning circulation loop. 3. Decoking cleaning: After the above steps are completed, if you want to add diluted cleaning agent to the system, when it is filled to one-half of the water level of the high tank, add an appropriate amount of decoking cleaning agent, almost 10% Up to 20%, we need to determine the specific dosage based on the scale thickness. The temperature is between 90 and 95 degrees Celsius, and the time should be determined according to the scale thickness, which is between 12 and 72 hours. 4. Rinsing and cleaning: After cleaning, we need to clean up the remaining night in the drainage system and add water to rinse until the coke cleaning agent has no foam and the water is clear. 5. Blowing steps: connect the air compressor at the pressure gauge or other connectable places, use compressed air to boost the system to 0.3-0.4MPa, and vent at each low point, and repeat until the water is blown out until. 6. Waste liquid treatment.
