Exhaust gas temperature of heat conduction oil boiler diesel burner

Actually, if the thermal oil boiler diesel burner is used according to the normal operation process, the exhaust gas temperature of the boiler diesel burner is not Will be significantly higher. However, the above-mentioned problems can easily be caused by the lack of attention of related companies or the negligence of operators in actual operation. So what are the specific reasons for these problems? It is understood that, first of all, the possible cause is the cracking of the flue wall of the heat-conducting oil boiler diesel burner, resulting in a short circuit of the flue gas, which effectively reduces the use of the heating surface, so it is reduced Heat transfer, causing the exhaust gas temperature to rise. Generally, the furnace should be shut down for maintenance. When the wall ash on the heating surface of the boiler diesel burner (usually accompanied by low-temperature corrosion), in addition to a large amount of fly ash and the flue gas flow is too low, it is often caused by blowing failure, especially when saturated steam is used for blowing. In the medium, the steam condensate deposited on the gray-scale surface condenses into a concrete shape. These conditions are also likely to cause similar problems. In addition, frequent starting and stopping of the furnace can easily cause condensation on the heating surface of the tail, which will aggravate low-temperature corrosion and ash blockage, which will increase the exhaust gas temperature. Of course, some companies blindly pursue unilateral economic benefits and choose to run the heat transfer oil boiler diesel burner over load, which will inevitably increase the amount of fuel. Secondly, the heat release of the boiler diesel burner will also increase, and the heat absorption of the heating surface cannot be significantly increased. The exhaust gas temperature will naturally continue to rise. Therefore, for the long-term development of the enterprise and better economic benefits in the future, the heat-conducting oil boiler diesel combustion engine cannot be continuously overloaded for a long time. Therefore, the abnormal rise in the furnace exhaust gas temperature of the heat-conducting oil boiler diesel combustion engine we mentioned will also be reduced. Troubleshooting 1. Outlet oil over temperature When the temperature of the outlet oil exceeds the upper limit set for the outlet oil temperature by 20°C or 350°C, the computer will flash the overheating temperature and forcibly shut down the controlled equipment. 2. The flue temperature is too high. When the flue temperature exceeds the set limit temperature of 300℃, the flue temperature is too high indicator will shut down the controlled equipment. 3. Low pressure difference. When the inlet and outlet oil pressure of the boiler diesel combustion engine is lower than the set pressure difference, the computer will indicate a fault and the controlled equipment will be forced to shut down. 4. Overpressure When the oil pressure of the boiler diesel combustion engine is higher than the set high pressure point, the computer will display a fault, thereby forcibly shutting down the controlled equipment. 5. Power prompt When the system power grid voltage exceeds the normal working range (180v-260v), the screen failure prompt will not interlock the equipment. Notes 1. For the thermal oil boiler diesel burner with thermal oil as the heat carrier, the system should be installed There are expansion tanks, storage tanks, safety elements, measuring instruments and control devices. 2. After the heat transfer oil is put into use, please start the circulating oil pump when starting to run. After running for half an hour, start to ignite and heat. It should be heated slowly during the first use. When the temperature rises to 180~200°C, it should be heated to about 20°C per hour and kept warm for a period of time before normal use. 3. It should be carefully checked during use to prevent water, acid, alkali and low boiling point substances from leaking 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 and supplemented or replaced according to the analysis results. Standard judgment: Alkaline carbon does not exceed 1.0%, acid value does not exceed 0.5mgk(OH)/g, ignition point change is not less than 20%, viscosity change does not exceed 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 should not be used at high temperature. The design and installation of the heating system of the heat-conducting oil boiler diesel combustion engine shall strictly follow the design regulations of the heat-conducting oil boiler diesel combustion engine formulated by the relevant state departments to ensure the safe operation of the system. !
