The technical scheme that solves the problems of the technologies described above is:
A kind of coal gas burner that can improve efficiency of combustion, it comprises the burner shell, the air inlet pipe, the coal gas inlet pipe, air lance, the air inlet pipe is connected with air port, its improvements are, in the inner cavity chamber of burner shell, also have coal gas dividing plate and coal gas manifold tube, the periphery of coal gas dividing plate is connected with the circumferential inner wall of burner is airtight, inner cavity chamber is divided into two parts with burner, the coal gas inlet pipe is in a side of coal gas dividing plate, air inlet pipe and air lance are at the opposite side of coal gas dividing plate, a plurality of coal gas manifold tubes are distributed in the cavity of air lance along the axially parallel of air lance, uniform ring is around central distribution on cavity cross-section, and an end of coal gas manifold tube passes the coal gas dividing plate, and is welded to connect with the coal gas dividing plate, the other end of coal gas manifold tube is positioned at the exit of air lance, is fixed by brace rod.
The above-mentioned coal gas burner that can improve efficiency of combustion is equipped with revolving fragment in each coal gas manifold tube inside, and revolving fragment is continuous flight, and length and coal gas manifold tube are isometric, and two ends and coal gas multithread tube wall are welded to connect.
The above-mentioned coal gas burner that can improve efficiency of combustion is welded with fixedly gusset between the coal gas manifold tube.
The beneficial effects of the utility model are:
1, in the burner internal structure, gas passage adopts the coal gas manifold tube, increased the spout flow velocity, and the gas exit of coal gas manifold tube is arranged in the exit of air lance, make the exit combustion gas and the air of burner can produce strong rapidly and blending uniformly, obtain higher flame temperature, improve efficiency of combustion.
2, externally mixed combustion of coal gas and air, the design of coal gas manifold tube has improved the adaptability to combustion gas and air pressure variations, and ability and adjustable range are bigger, have reduced the possibility of tempering, have improved efficiency of combustion and safe handling property.
3, set up revolving fragment in the coal gas manifold tube, can adjust the length of flame by the different pitch of revolving fragment, the length of flame just in time is in the middle of the stove, fire box temperature is even, and it is even to add temperature for steel billet, is beneficial to control.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the structural representation of revolving fragment of the present utility model;
Fig. 4 is the side view of Fig. 3.
Mark is as follows among the figure: burner shell 1, air inlet pipe 2, coal gas inlet pipe 3, air lance 4, coal gas dividing plate 5, coal gas manifold tube 6, revolving fragment 7.
The specific embodiment
Fig. 1,2 shows that the utility model is made up of burner shell 1, air inlet pipe 2, coal gas inlet pipe 3, air lance 4, coal gas dividing plate 5, coal gas manifold tube 6, revolving fragment 7.
Have coal gas dividing plate 5, coal gas dividing plate 5 that burner inner cavity chamber is divided into two parts in the inner chamber body of burner shell 1, a part is connected with coal gas inlet pipe 3, and another part is connected with air inlet pipe 2, and air lance 4 and air inlet pipe 2 are in the chamber of homonymy.Burner shell 1, air inlet pipe 2 can determine according to the actual installation size with coal gas inlet pipe 3, guarantees that exterior line remains stationary.
Coal gas manifold tube 6 is a plurality of, is the long tube of being made by metal, is arranged in the cavity of air lance 4 along the axially parallel of air lance 4, and from the cross section of the cavity of air lance 4, a plurality of coal gas manifold tube 6 uniform ring are around the center of cavity cross-section.One end and the coal gas dividing plate 5 of coal gas manifold tube 6 are welded to connect, and coal gas can be by the exit ejection of coal gas manifold tube 6 from air lance 4 from the chamber of coal gas inlet pipe 3, and the welding gusset prevents the changing of the relative positions between the coal gas manifold tube 6.
