[0019] Figure 1It is a schematic structural diagram of a natural gas gun head mixing device in an embodiment of the present utility model.

[0020] As Figure 1 shown, the natural gas gun head mixing device 100 in this embodiment is used to mix natural gas and combustion-supporting gas and then spray it.

[0021] The natural gas gun head mixing device 100 includes a gas supply device 10, a mixing device 20, and a spraying device 30.

[0022] Among them, the gas supply device 10 includes a natural gas supply pipe 11 and a natural gas supply pipe gun head 13.

[0023] The natural gas supply pipe 11 and the natural gas supply pipe gun head 13 are threadedly connected through a natural gas supply pipe joint 12, which is convenient for replacement and can be replaced and adjusted according to different working conditions such as different gas pressures and calorific values in different regions, so as to adjust to meet the requirements of the overall load of the burner on site, greatly increasing the applicability.

[0024] The natural gas supply pipe 11 and the natural gas supply pipe joint 12 are welded together.

[0025] The mixing device 20 includes a natural gas mixing pipe 21 and a natural gas mixing pipe joint 22.
