Process characteristics of fuel burner

Process characteristics of fuel burner
Oil is a liquid fuel, and its boiling point is always lower than its ignition temperature, so the combustion of oil is actually carried out in a gaseous state. When oil is burned, it is not the liquid oil that directly participates in the combustion, but the "gas". Therefore, the combustion of oil droplets includes three processes: transpiration, loosening, and combustion, which occur together. The fuel burner has the following characteristics: oil burns in a state of transpiration and gasification, oil has the characteristics of loose combustion, oil needs to be atomized before combustion, oil has different thermal decomposition under different conditions, and there are two types of fuel atomization. One method is pressure mechanical atomization, which uses high pressure to transfer fuel through a rotating device at high speed, and then further accelerates it to break into small oil droplets through the nozzle, To achieve the purpose of atomization. Another method is to perform mechanical atomization with the participation of the medium. The former has two methods: simple mechanical atomization and reflux mechanical atomization, and the mechanical atomization involving medium includes steam atomization and air atomization.
The most widely used oil-fired boiler is the steam atomization burner. The research and development of domestically produced steam atomization burners has reached a high level, with outdated and stable skills. In general, the working environment temperature of fuel burners should not exceed 70 ° C, otherwise cooling and insulation methods should be used. The use of fuel burners should be prevented from operating in humid environments. Replace the oil nozzle once a year, and replace the elastic coupling and rubber components on the coupling once a year. Prevent aging of accessories. At the same time, it is necessary to ensure that foreign objects are prevented from entering the air duct to prevent accidents from occurring. At the same time, timely check the combustion tube, impeller, flame detector, and combustion electrode to remove oil and carbon deposits. Especially the flame detector should be kept clean and not damp. Adjust the oil pressure appropriately according to the indicated oil pressure value. Also, check whether the connection between the fuel burner and various components is firm, loose, and the direction has changed to ensure the normal operation of the fuel burner. The fuel burner only needs to check its operation on time and maintain it properly, which will greatly improve the efficiency of the burner and bring about a long-term stable operating environment.
