Heat oil boiler diesel burner fuel injection

Nowadays, my country’s heat-conducting oil boiler diesel combustion engine industry continues to develop, and it has launched more and more heat-conducting oil boiler diesel combustion engines. Advanced and user-friendly, greatly reducing the labor intensity of employees and improving work efficiency. So it is widely used in various occupations, and now it is our indispensable right-hand man; and below we explain in detail how to prevent fuel injection from boiler diesel combustion engines. We feel very confused. Does the heat-conducting oil boiler diesel combustion opportunity spray oil? The thermal oil experts pointed out that the original thermal oil boiler diesel combustion opportunity will appear on the oil scene. If we use the thermal oil boiler diesel burner, improper operation will cause the thermal oil boiler diesel burner to have fuel injection; through years of research , Shanghai Jinuo Chemical Co., Ltd. It is found that there are several reasons for the formation of the oil injection of the thermal oil boiler diesel burner: 1. When we clean the thermal oil boiler, it must be clean and very clean. If there is residual water in the boiler diesel burner, oil injection will occur if the cleaning method is not correct. 2. Thermal oil experts suggest that when we choose and purchase thermal oil, we must strictly choose better quality heat transfer oil. If the quality of heat transfer oil is poor, it will also cause oil injection. 3. When using the thermal oil boiler diesel burner, the staff must operate accurately, especially at the edible oil dehydration exhaust of the thermal oil boiler diesel burner. There is no water in the closed loop system, but there is water in the upper tank. The water in the original circulation system enters the high water tank through the auxiliary exhaust pipe. The temperature of the high water tank is only 60 degrees, and only a small amount of water vapor is discharged. Most of the water vapor condenses and accumulates in the high water tank. After the heat transfer oil temperature rises, its volume expands and is pushed into the high water tank. The heat transfer oil in the high water tank is heated to 140 degrees, and the water in it boils and is injected with air or oil. The thermal cracking of the heat transfer oil produced a large amount of light components. Due to the outlet pressure gauge of the boiler diesel burner, a large amount of gas was actually collected in the pipeline, which was noisy. The workers did not notice the sound of the air hammer. Later, the gas in Chengdu The concentration, through the oil and gas separator, suddenly overflowed to the high tank, because of the high pressure and oil. Safety countermeasures (1) Ensure the safety of equipment The heat transfer oil heating system should be managed as a pressure equipment to ensure that the heating equipment is intact and leak-free, otherwise the consequences will be very serious. During use, the wall thickness and compressive strength of the equipment should be measured regularly, and pressure gauges, safety valves and blow-out pipes should be installed on the equipment and pipelines. (2) Strict and safe operation When using the heat-conducting oil furnace light oil burner, the temperature should not exceed 350°C to prevent the temperature from rising above the pressure and causing danger. In order to avoid overheating of the pipe wall on the heating surface of the heat transfer oil, the flow of the heat transfer oil should be turbulent, that is, Reynolds number Rc> 10000, and have a certain speed, so as to reduce the thickness of the boundary layer when flowing over the heating surface. During the heating operation, the circulating pump with the heated body is not allowed to stop. When the thermal load is reduced or temporarily stopped, the bypass return valve should be opened to adjust the flow of the system so that the heat transfer oil in the pipe has sufficient flow and velocity. The heating furnace starts at the beginning of air preheating of the heating surface pipes and system pipes. When the ignition starts to heat up, the heat transfer oil has low temperature, high viscosity, slow speed, and thick film layer. The heating speed must be strictly controlled, generally below 40-50℃/h, in order to avoid local heat overheating. When the temperature of the circulating heat transfer oil is high but the temperature of the thermal equipment cannot be increased, the outlet temperature of the heat transfer oil should not be increased blindly, and thermal equipment, such as a scale, should be used. When using heat transfer oil, pay attention to the temperature and pressure at the beginning of the startup The relationship between. If the pressure is too high and the temperature is too low, it means that there is water and should be exhausted in time; if the pressure is low and the temperature is high, it means that the heat transfer oil is insufficient. When the system stops running, the heat transfer oil circulating pump should continue to run for a period of time. After the heat carrier is cooled, all the heat transfer oil in the system should be heated. (3) Ensure the heat conduction of oil and water. It is forbidden to mix heat transfer oil with water or other low-boiling impurities and flammable and explosive substances. When starting the car, the water in the system should be drained first, and then the intake valve and check valve should be opened, and heated as required to remove the water in the heat carrier; the newly added or added heat transfer oil must be preheated and dehydrated before being added. When eliminating water, first open the air valve, and then use a small flame to increase the temperature of the heat transfer oil to 150°C at a rate of 5°C/h to allow the water to evaporate and escape. Then lower the exhaust valve and raise the temperature to 250°C at a rate of 10°C/h. During the heating process, if there is water knocking sound or high pressure, immediately open the exhaust valve to discharge water vapor, and then close the exhaust valve to start. When stopping the furnace, close the steam valve of the light oil burner of the heat-conducting oil furnace after releasing the heated material to avoid material leakage into the system. (4) Removal of coking and scaling. In production practice, it is safe for the coking thickness to be less than 2mm, and the coking layer in the furnace tube is between 0 and 1.5mm. At this time, the continuous accumulation of the coking layer is roughly balanced with the melting amount washed by the heat carrier. The thickness of the coke layer in the furnace tube can be measured by an ultrasonic thickness gauge. A filter should be installed at the inlet of the circulating pump to remove suspended polymers and carbon particles precipitated by local overheating caused by chemical changes. The filter should be easy to disassemble and replace in order to clean up the residue and impurities regularly to ensure the filtering effect. (5) Strengthening safety management should pay attention to formulating and implementing technical specifications and management regulations for the operation of hot oil heating equipment, and strictly abide by relevant laws, regulations and safety operating procedures. The heat conduction oil heating operation should have a complete emergency treatment plan, especially to prevent the occurrence of overflow, spraying materials, leakage, overload and disease operations. Once the leakage point, stop the leakage immediately and replace the insulating cotton. (6) Set up safety devices Set up temperature, pressure, flow, liquid level automatic adjustment system, alarm system and safety release device to ensure the sensitive use of instruments. During the heating operation, if the pressure suddenly rises, immediately open the exhaust valve to release the pressure, and close the valve of the heat carrier pipe to the heating device. !
