Structure composition of automatic natural gas burner
The automatic natural gas burning burner is composed of two parts: the burner body and the gas valve group. The initial combustion body mainly includes the fan, the motor unit, the combustion tube, the ignition system, the flame detector, the damper adjustment, the natural gas nozzle, the stabilizer, etc. Components: The gas valve group mainly includes manual valves, safety valves, regulating valves, natural gas filters, connecting pipes and other components. The electric adjustment of the upper air door of the burner body and the choker in the gas valve group constitute the natural gas air proportional adjustment system of the burner. It is in turn issued by the program controller and the state controller to implement various working condition adjustments and safety interlocks. protection. In addition, the natural gas-air ratio adjustment of the burner can also adopt a mechanical linkage type proportional copper joint. Fully automatic gas burners have the following advantages in terms of structural performance, manufacturing process, and product serialization;
1. It can burn all kinds of fuel gas, including natural gas, liquefied petroleum gas, city gas, etc.
2. The burner has a variety of adjustment methods. The low-power burner adopts one-stage and two-stage adjustment methods. The medium and high-power burner adopts the mechanical domain electronic proportional adjustment method to ensure the reasonable ratio and high efficiency of natural gas and air. combustion.
3. Pollutant emissions in combustion products are in line with international standards. The low-polluting natural gas burner has NO2 emissions lower than 150mg/m3. The structure of the fully automatic natural gas burner is shown in the figure below.
