Coal gas burner is widely used in the various industrial furnaces that coal gas is fuel of take.Existing coal gas burner is generally the overall structure of being made by steel, can only integral replacing after part damages, and the service life of burner is short.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of hot gas flat-flame nozzle of dismountable, long service life is provided.
According to technical scheme of the present invention: a kind of hot gas flat-flame nozzle, comprise air hose and gas pipe, on the sidewall of described gas pipe, be fixed with gas entry pipe, one end of described gas pipe is provided with gas pipe flange, on the outer wall of described air hose, be fixed with cover plate, described air hose stretches in described gas pipe and described cover plate is connected on described gas pipe flange by securing member.
Described cover plate is fixed with ring flat-plate in the face of on the side of described gas pipe flange, and described ring flat-plate stretches in described gas pipe, between described ring flat-plate and described air hose, is provided with burner liner.
Described air hose consists of the first steel pipe, reducing joint, the second steel pipe and Taper Pipe successively along airintake direction, the end of described the first steel pipe is fixed with air hose flange, the diameter of described the second steel pipe is less than the diameter of described the first steel pipe, described Taper Pipe is the little structure in large the inner, outer end, the material of described the first steel pipe and described reducing joint is carbon steel, and the material of described the second steel pipe and described Taper Pipe is stainless steel.
Described the second steel pipe is provided with near the inside of described Taper Pipe spinning disk and the stable flame pan of being made by stainless steel material.
Described gas pipe and described gas entry pipe inside are provided with burner liner.
The gas exit place of described gas pipe is throat structure.
Described gas exit place is provided with stainless steel endless tube, between described endless tube and described gas pipe, is provided with stainless steel gusset.
On the outer wall of the described gas pipe at described gas exit place, be fixed with square flange.
Technique effect of the present invention is: the present invention is connected to air hose on gas pipe by flange and securing member, can pull down replacing from gas pipe, thereby extended the service life of burner when air hose scaling loss; Air hose is made by carbon steel material and stainless steel material, and carbon steel material is positioned at low-temperature space, and stainless steel material is positioned at high-temperature region, has both guaranteed service life, has reduced again material cost; In air hose, be provided with spinning disk and stable flame pan, can guarantee to form stable flat flame.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, comprise stable flame pan 1, Taper Pipe 2, gusset 3, square flange 4, endless tube 5, spinning disk 6, the second steel pipe 7, reducing joint 8, gas pipe 9, the first steel pipe 10, ring flat-plate 11, gas pipe flange 12, cover plate 13, air hose flange 14, bolt 15, nut 16, gas entry pipe 17, burner liner 18, gas exit 19, air hose 20 etc.
As shown in Figure 1, the present invention is a kind of hot gas flat-flame nozzle, comprises air hose 20 and gas pipe 9.
