[0002] Gas burners are divided into natural gas burners and city gas burners, etc. They are devices that convert substances into heat energy through the chemical reaction of combustion. In other words, air and fuel are mixed in an appropriate proportion through a premixing device to ensure complete combustion. Fuel and air are sent into the furnace according to the required concentration, velocity, turbulence and mixing method, and the fuel can be stably ignited and burned in the furnace. The fuel is mainly oil and gas. They are generally used in small and medium-sized boilers. Gas burners mainly consist of an air supply system, an ignition system and a detection system.
