According to its working principle, a burner can be defined as a device that converts substances into heat through the chemical reaction of combustion - that is, air and fuel are mixed in an appropriate proportion through a premixing device to make it fully burned. The burner is a thermal energy device that feeds fuel and air into the furnace according to the required concentration, velocity, turbulence and mixing mode, and enables the fuel to stably ignite and burn in the furnace. The fuel is mainly fuel oil and gas. Generally used in small and medium oil or gas boilers . Gas burners are divided into natural gas burners , city gas burners, etc.
According to the fuel atomization method, it is divided into : mechanical atomizing burner, medium atomizing burner ;
According to the structure, it is divided into : integral burner and split burner. Among them, the split burner is mainly used in industrial production, and its main feature is that the combustion system , air supply system, control system, etc. are all disassembled and installed. This kind of machine is mainly suitable for large equipment or special working environments such as high temperature.
Relatively speaking, commercial burners are relatively inexpensive due to mass production and low specialization requirements in the market supply chain, while split burners have relatively high specialization requirements, and Most require a professional installation team, and the market sales price is relatively much higher than the same period last year.
The gas burner construction consists of the following 5 systems :
1. Air supply system The function of the air supply system is to send air with a certain wind speed and air volume into the combustion chamber. Its main components are : shell, fan motor, fan impeller, air gun fire pipe, air door controller, air door baffle , Cam adjustment mechanism, diffuser plate.
2. Ignition system
The function of the ignition system is to ignite the mixture of air and fuel, and its main components are : ignition transformer, ignition electrode, electric fire high-voltage cable.
3. Monitoring system
The function of the monitoring system is to ensure the safe and stable operation of the burner , and its main components include a flame monitor, a pressure monitor, and a temperature monitor.
4. Fuel system
The function of the fuel system is to ensure that the burner burns the required fuel. The fuel system of the oil burner mainly includes : oil pipe and joint, oil pump, solenoid valve, nozzle, heavy oil preheater . Gas burners mainly include filters, pressure regulators, solenoid valve groups, ignition solenoid valve groups, and fuel butterfly valves.
5. Electronic control system
The electronic control system is the command center and contact center of the above systems. The main control element is the program controller. Different burners are equipped with different program controllers. The common program controllers are : LFL series, LAL series, LOA series, LGB series , the main difference is that the time of each program step is different.
当可燃气体(城市煤气、天然气、液化石油气)由微电脑控制系统按程序控制进入燃烧器的燃烧头内，由一次风与可燃气体混合，点火燃烧，二次风助燃，实现充分燃烧。燃烧状况由火焰自动跟踪系统检测控制燃烧，当燃烧出现故障(燃烧室缺氧、可燃气体欠压、可燃烧气体断流、气量不足等)，控制系统发出指令，供气系统的电磁阀迅速关闭，切断气电源，燃烧器自动吹扫后停机，指示故障。1 )热效率高 :能适应压力波动，自行调节一次配风 ( 即燃气压力大，吸入一次风多;燃气压力小，吸入一次风少 ) ，燃烧充分，热效率高;
( 3 ) 燃料适应性强:该种燃烧器只需更换少量部件就能适用于天然气、液化石油气、煤气、液化石油混合气以及其它类燃气
(2) The second is : when artificially shutting down and switching off the shift, the operator should follow the reverse sequence when starting up (a. Turn off the combustion control button first, b. Turn off the fan button, c. Turn off the power button at last twist ) to operate the shutdown.
(3) When the shutdown time is long, the operator should close the gas pipeline valve to avoid gas leakage .
