What Is Natural Gas Combustion?
Natural gas burner is one of the main combustion equipment of natural gas. Divided according to the burner's combustion control mode: single-stage fire burner, double-stage fire burner, proportional adjustment burner. Natural gas has a wide range of applications, which can be roughly divided into two aspects: energy and chemical. Energy is mainly natural gas combustion equipment, of which natural gas burner is one of the main combustion equipment of natural gas. In the broad sense of the burner concept, domestic water heaters, gas stoves, and even lighters can be considered as a type of burner. According to its working principle, a burner can be defined as a device that converts heat energy through the chemical reaction method of burning substances-that is, air and fuel are mixed in a proper ratio through a premixing device to make it fully burn.

- Natural gas burners are divided into civil and industrial. China's civil combustion equipment has developed rapidly. Mainly imitating Japanese and European products. There is a certain gap between high-end products and advanced countries. However, with the exception of a few imported equipment for industrial combustion equipment, most of the industrial burners developed by ourselves are relatively backward. Obviously, tens of billions of natural gas cannot be used for civilian use every year. First, natural gas is used for power generation, and second, it is used in various industries. With the progress of natural gas engineering, a series of energy-saving and low-polluting burners that are necessary for different processes should be developed. Not only can companies make it affordable, but they can also improve the quality of their products. In this way, natural gas can be delivered there, where it can be digested in situ, and the economic and social benefits of natural gas saving energy, reducing pollution, improving product quality, and promoting national economic growth can be fully utilized. Therefore, we must improve China's natural gas application technology, and the development of advanced burners is an urgent task.
- The maintenance of natural gas burners should start from the main gas source, filters, control regulating valves, burners and other links. Main gas source for natural gas burners-For natural gas fueled burners, check the main gas source regulating valve to ensure that the line is intact. Do not adjust the control valve of the gas company. The gas company will assist in cleaning, maintenance and adjustment of the main gas source control valve. If there is a sensing line, inspect it for damage. Natural Gas Burner Filter-If a "y" filter is installed before the control valve is controlled, care must be taken to clean it. Control valve-Check the control valve on the gas burner to see if the adjusting bolt is easy to adjust. Make sure all outlets and screens are not blocked. Burner-check the gas pipe group, and confirm whether the manual switch adjustment is sensitive and the valve handle is installed. Check if the barometer is working properly. When adjusting a gas burner, accurate pressure display is critical. Turn the low and high pressure switches to verify their operation. The connection of the air valve needs to be cleaned and lubricated. If the connection is sticky or too rough, replace the appropriate accessories. If the burner is equipped with removable pipes, care should also be taken to clean it.
