TECHNICAL FIELD

[0001] The utility model relates to a boiler gas supply technical field, concretely relates to a novel boiler gas supply device for improving the boiler combustion efficiency and optimizing the gas supply structure. BACKGROUND

[0002] A boiler is a device that converts water into steam or hot water by heating, widely used in industrial production, power generation, heating and other fields. Its core function is to convert chemical energy into heat energy by burning fuel (such as natural gas, coal, etc.), thereby providing a stable heat source. The performance of the boiler is directly related to the energy utilization efficiency and the degree of environmental pollution, so the optimization of its combustion efficiency and gas supply system is crucial.

[0003] The traditional boiler gas supply device usually adopts a straight injection design when in use, and the mixing effect of fuel and air is poor, which not only requires more fuel for combustion, but also causes uneven distribution of combustion temperature. Such uneven combustion temperature not only reduces the thermal efficiency of the boiler, but also may cause local overheating and damage the internal structure of the boiler; in addition, the structure design between the air supply pipe and the gas pipe of the traditional gas supply device lacks optimization, and air and fuel are prone to turbulent flow when entering the combustion chamber, resulting in uneven airflow distribution. Such airflow turbulence not only affects the stability of combustion, but also may cause local temperature of the flame to be too high or too low, further reducing the thermal efficiency of the boiler. Therefore, there is an urgent need for a new type of boiler gas supply device to solve the above problems. SUMMARY

[0008] The connecting pipe is connected to one end of the air supply pipe by screw thread, and the other end of the connecting pipe is rotatably connected to the gas pipe by a positioning frame.

[0009] As a preferred technical scheme of the utility model, the air supply pipe and the gas pipe are concentrically arranged.
