Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As Figure 1-4, the utility model includes blower fan 1, gas mixing unit, mixed cyclonic current device, metallic fiber combustion
Burn first 5；Gas mixing unit is made up of spindle 2 and hybrid chamber 3；The arrival end of hybrid chamber 3 passes through one with the port of export of blower fan 1
Number flange 6 is connected；Spindle 2 is bicone structure, and spindle 2 is fixedly installed on the arrival end of hybrid chamber 3 by support member
On pipeline, be conducive to further diffusing to the air at fan outlet in hybrid chamber 3, improve the mixing journey of combustion gas and air
Degree；The arrival end of blower fan 1 is provided with air filter 12, the impurity being used in air filtering, prevents impurity from entering metal fine
Tie up inside combustion head 5, improve the service life of combustion head；Air filter 12 is radial ventilation mouthful.
