Description

Technical Field

[0001] The utility model relates to a burner, in particular to a burner for a boiler. Background Art

[0002] In order to reduce the pollutant content in boiler flue gas and improve combustion efficiency, metal surface burners are usually used. This type of burner first mixes natural gas with combustion air to form an unburned mixed gas. After the mixed gas is sent into the metal combustion rod, it is sent into the furnace for combustion after passing through the metal fiber felt on the surface of the metal combustion rod. This type of burner allows the gas to be fully mixed with the combustion air before combustion, which reduces the combustion flame temperature, effectively inhibits the generation of thermal types, and improves combustion efficiency. The gas flow surface gap of the metal fiber felt on the surface of the metal combustion rod is small, and particulate matter in the combustion air often accumulates in the gap, increasing the workload of burner maintenance; if maintenance is not in place, there will be safety hazards such as gas explosion and combustion backfire.

The utility model discloses a high-efficiency burner for a gas boiler, including a wind wheel, a burner housing, a motor, a combustion head and a boiler flange. A motor is fixed to the side wall of the burner housing, and the motor is connected to the wind wheel inside the burner housing through a motor shaft. A boiler flange is sleeved inside the outlet end of the burner housing, and a combustion head is fixed to the end of the boiler flange by bolts. In the utility model, a combustion mesh cover is arranged inside the combustion head, and the inner diameter of the combustion mesh cover gradually increases from the inside to the outside. A plurality of branch pipes arranged at equal angles are connected through an annular tube, and then nozzles facing the center of the combustion head are equidistantly arranged on the outer wall of the branch pipe.

[0004] Although the existing technology makes the fuel injection range wider and increases the probability of fuel contacting the combustion mesh cover, so that when the fuel burns, the wind resistance is enhanced, the fuel burns faster and more fully, and the combustion efficiency of the burner is improved, but there are safety hazards in the combustion of mixed gases in the existing technology.
