In the broad concept of burner, domestic water heater, gas stove and even lighter can be regarded as a kind of burner. According to its working principle, the burner can be defined as a kind of equipment that converts substances into heat energy through the chemical reaction of combustion - that is, air and fuel are mixed in an appropriate proportion through the premixing device to make it burn fully.

   Burner is a thermal energy device that sends fuel and air into the furnace according to the required concentration, speed, turbulence and mixing mode, and enables the fuel to ignite and burn stably in the furnace. The fuel is mainly fuel oil and gas. It is generally used in small and medium-sized oil or gas boilers.

   Gas burners are divided into natural gas burners, city gas burners, etc. According to the combustion control mode of burner: single-stage fire burner, double-stage fire burner and proportional regulation burner. According to the fuel atomization mode, it is divided into mechanical atomization burner and medium atomization burner.

   According to the structure, it is divided into integral burner and split burner. The split burner is mainly used in industrial production. Its main feature is that the combustion system, air supply system and control system are disassembled and installed. This kind of machine is mainly suitable for large equipment or special working environment such as high temperature.
