Heat conduction oil boiler diesel burner does not circulate

Heat transfer oil is a forced circulation system organic chemical load furnace. When the saturation pressure is lower than 6.86×104pa, its operating temperature reaches 2600 degrees. It has the characteristics of bottom pressure and high temperature work, and is used in chemical plants, textiles, light industry, printing and dyeing plants, paper industry, decorative building materials and other manufacturing industries. The risks and solutions: First, the bulge and the water pipe burst causing a fire accident. The oil is not very good, and the residual carbon in the oil exceeds the standard. The high temperature heat transfer oil is accidentally stored during the whole process of storage, transportation, operation and maintenance, so that moisture, residue or other oil can penetrate into the high temperature heat transfer oil. When the high-temperature heat-conducting oil is heated to 1500°C, it will cause the oil pump to catch fire, or the water will be heated and vaporized, resulting in high pressure, resulting in the destruction of machinery and equipment. Explosion due to overpressure. In addition, the residual carbon index value in the oil exceeds the standard. High-temperature heat transfer oil will produce certain chemical reactions during the whole heating process, which will be converted into a small amount of polymer, and at the same time, it will also be converted into coke due to partial overheating. This polymer and residual carbon do not dissolve the oil and float in the oil. In operation, this chemical substance will accumulate at the bottom of the steam drum, causing the bag to over-temperature, and accumulate on the wall thickness, causing the pipeline to over-temperature. Therefore, we should carry out sampling and analysis of high-temperature heat transfer oil on time, pay close attention to the quality of high-temperature heat transfer oil, analyze the reason for the change, and fill in the use of new high-temperature heat transfer oil on time to stabilize the residual carbon amount. The high-temperature heat transfer oil added to the heating furnace must be dried beforehand to find problems. Effective countermeasures should be taken immediately. The inlet and outlet temperature is too high and the total flow is too low. Sometimes the heat engine temperature is too high because the car oil temperature is too high, which does not meet the manufacturing requirements. Some generator sets choose to increase the inlet and outlet temperature to ensure heating. Therefore, the inlet and outlet temperature is close to or exceeds the maximum allowable application temperature of a heat carrier, thereby increasing the level of coking and fouling, and the heat transfer efficiency of the heat pipe radiator using the heat engine is low. Until the furnace body exploded polarization. In addition, if the water flow rate is too low, the temperature of most of the heating surfaces or part of the pipeline cavity will be higher than the allowable slick temperature. The normal service life of high-temperature heat transfer oil will be reduced, and over-temperature will cause bursting. Therefore, the maximum oil temperature of the heating furnace should be 30°C lower than the operating temperature of a heat carrier to prevent the oil from dissolving mildew during the entire application process. In operation, the water flow rate of the high-temperature heat transfer oil outside the heating surface tube of the radiation source is not less than 2m/s, and the water flow rate outside the heat convection tube is not less than 1.6m/s to avoid carbon residue, blockage of the tube and over-temperature. Wall thickness. Secondly, the leak caused a fire accident. Due to the welding quality of electric welding, part of the main body of the heat medium transportation is dropped or a lot of vaporization in the condition of excessive temperature, which causes the pipeline to vibrate and even destroy, causing a lot of high-temperature heat transfer oil to leak. The high-temperature heat transfer oil has a strong Hydrophilicity, especially at the flange sealing ring. More serious fire accidents generally occur after fire accidents. Therefore, during installation, be sure to choose a qualified installation engineering company to carry out the installation. The pipeline connection is welded by electric welding, and the looper flange is suitable. Do not tighten. When looping flanges, use high-toughness graphite products with acid and alkali resistance, working pressure resistance, and heat resistance. As a sealing ring. All notes that touch with a heat carrier cannot be made of rare metals and pig iron. Seamless steel pipes should use No. 20 seamless pipes and standard parts, especially the connecting anchor bolts on the main loop. Before the heating furnace fires, the boiler supervision company and the installation engineering company carry out hydraulic tests on all pipelines and gate valves until the high-temperature heat transfer oil in the system software pipeline leaks for more than 65 minutes. After confirming that there is no problem, only fire up. 3. Negligence during a power outage will cause a fire accident. When the heat transfer oil is used normally, the generator set sometimes loses power suddenly. At this time, the gasoline pump of the circulation system stops working, the coal is ignited in the furnace again, and the temperature of the heating furnace oil rises again. If the temperature of the car's oil increases too quickly, it will decrease. In a short period of time, the temperature of the oil will partly rise and coke, causing over-temperature and over-temperature pipes to cause fire accidents. Therefore, in the event of a power outage such as a power outage, all furnace ports should be opened to immediately remove the remaining coal in the furnace, so that a lot of strong cold air enters the furnace, quickly reduce temperature control, and remove pyrogens; turn on the heating furnace to release The oil valve makes the high-temperature oil slowly enter the oil storage tank, and the cold oil in the swelling oil storage tank is slowly injected into the heating furnace, which immediately takes away the heat. There are standard modules that can be configured with two-way switching power supplies. For example, each medium and small diesel generator is installed, and the power circuit and the circulation system gasoline pump power circuit are mutually converted to avoid excessive water temperature after a power failure, causing coking and safety accidents. On the other hand, furnace workers must go through the training of the quality supervision unit and be awarded the 'Special Operation Certificate of the Manufacturer'. Can only have the ability to operate alone to ensure that the abnormal phenomenon is cleared immediately. Keep the gasoline pump and storage tank clean of the circulation system together to eliminate the vegetable grease and dust accumulated on the surface anytime and anywhere, and avoid the ignition of external flying fire. Abnormalities in the heat-conducting oil circulating water pump and solutions a) When the current of the heat-conducting oil circulating water pump is less than the standard value, the high efficiency of the circulating water pump will be reduced, the total flow will be reduced, and the heating pipeline will be blocked by fouling and should be cleaned and tidy. b) The working pressure of the circulating water pump will not change, the current flow will expand, and the total flow will decrease. High temperature heat conduction oil moldy and viscosity increase. It should be replaced or rebuilt immediately. If the water content is not removed in the system software or the newly heated conductive liquid is dissolved, the automatic exhaust valve should be opened first to discharge the vapor. c) When the current of the heat transfer oil circulating water pump decreases, the pump pressure at the inlet and outlet returns to zero, indicating that the pump speed is not high. It will be oil and gasification, and effective investigation should be taken to find out the cause of gasification; if the filter device is blocked, the circulating water pump should be drained first, and the bypass should be opened to clean the filter device; if the newly heated fluid mechanics contains water or water is dissolved In the system software, the automatic exhaust valve should be opened first to start the exhaust pipe. d) High-efficiency liquid phase is a kind of heat carrier heating furnace with low inlet and outlet temperature, insufficient heat transfer oil heating, and organic waste gas temperature exceeding 400°C. The key is the problem of dust accumulation, which should be purged immediately. If the exhaust pipe temperature is low, the key is to ignite the problem, the key is because of insufficient steam intake. Despite the positive pressure of the heating furnace, the amount of engineering blasting is not large, the temperature of the heating furnace is low, and the ignition compressive strength is not enough.
