Process Characteristics Of Fuel Oil Burner
Process Characteristics Of Fuel Oil Burner
Oil is a liquid fuel. The boiling point of liquid fuel is always lower than its ignition temperature, so the combustion of oil is actually carried out in the gaseous state. When oil is burned, it is not oil in a liquid state that directly participates in combustion, but “gas”. Therefore, the combustion of oil droplets includes three processes: transpiration, loosening, and combustion, which are carried out together. The oil burner has the following characteristics: the oil burns in the transpiration and gasification state, the oil has the characteristics of loose combustion, the oil needs to be atomized before burning, the oil has different thermal decomposition under different conditions, and there are two types of fuel atomization. One method is pressure-type mechanical atomization, that is, the fuel is transmitted at high speed through the rotating device using high pressure, and then it is further accelerated to break into small oil droplets through the nozzle, To achieve the purpose of atomization. The other is mechanical atomization with the participation of the medium. The former has two methods: simple mechanical atomization and reflux mechanical atomization. The mechanical atomization involving medium includes steam atomization and air atomization.
The most widely used oil-fired boiler is the steam atomizing burner. The research and development of domestic steam atomizing burners have reached a high level, and the skills are old and stable. In general, the working environment temperature of the oil burner shall not exceed 70 ° C, otherwise, the cooling and insulation method shall be adopted. The use of oil burners shall prevent operation in humid environments. Replace the oil nozzle once a year, and replace the elastic coupling and rubber parts on the coupling once a year. Prevent parts from aging. At the same time, ensure that foreign matters are prevented from entering the air duct to prevent accidents. At the same time, check the combustion tube, impeller, flame detector, and combustion electrode in time to remove oil and carbon deposits. In particular, the flame detector shall be kept clean and not wet. Adjust the oil pressure properly according to the indicated oil pressure value. Also check whether the connection between the fuel burner and each component is firm, or loose and whether the direction is changed to ensure the normal operation of the fuel burner. The oil burner only needs to check the operation of the burner on time and do a good job in the maintenance of the burner, which will greatly improve the efficiency of the burner and bring about a long-term stable operating environment.
