[0002] A gas boiler is a heating device that usually uses liquefied petroleum gas or natural gas as fuel. It generates heat energy by burning liquefied petroleum gas or natural gas, and transfers it to boiler water or steam, ultimately achieving the purpose of heating or hot water supply. Gas boilers are more environmentally friendly and efficient than traditional coal-fired boilers, and are widely used in households and industrial fields.

[0003] The low-nitrogen burner of a gas boiler is a burner designed to address the problem of nitrogen oxide emissions generated during the combustion process. The low-nitrogen burner of a gas boiler can reduce the emission of nitrogen oxides and achieve environmental protection and emission reduction. During the combustion process, the low-nitrogen burner reduces the generation of nitrogen oxides by optimizing the combustion process, increasing air preheating and lowering the combustion temperature. The low-nitrogen burner of a gas boiler ensures full combustion of the fuel while reducing pollution to the environment.

[0004] However, conventional gas boiler low-nitrogen burners are not convenient for accurately adjusting the use height of the burner, and since the actual installation ground is not completely horizontal and the axis of the fuel delivery pipeline connection port is not completely horizontal, the gas boiler low-nitrogen burner and the fuel delivery pipeline are difficult to install. Therefore, there is an urgent need for a low-nitrogen combustion device for gas boilers that can accurately adjust the use height of the burner and is easy to install. Utility Model Content
