3, adopt modularized design, structure wants simple compact than common premix burner space gas pipeline, is convenient to process and assemble.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation that the utility model is applicable to the space gas blender of burner;
Fig. 2 is that the utility model is applicable to the structural representation that the space gas blender of burner is connected with pipeline;
Fig. 3 is the front view of automatic ignition line style burner;
Fig. 4 is the side view of automatic ignition line style burner.
The specific embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
As shown in Figure 1, the space gas blender that is applicable to burner of the present utility model comprises the mixture 1 of hollow, and mixture 1 is provided with air inlet 3, gas inlet 5 and mixed gas outlet.
Blender carries out air and coal gas premix, can guarantee that air and coal gas mix on shorter pipeline.The utility model adopts modularized design, and structure wants simple compact than common premix burner space gas pipeline, is convenient to process and assemble.
Further, the length of control wind body 2 is greater than the internal diameter of gas inlet, and the internal diameter size of control wind body 2 is 1/2～3/4 of its external diameter size, can further improve the injection effect of coal gas.In a preferred embodiment, the internal diameter size of control wind body 2 is 5/8 of its external diameter size.Mixture 1 and control wind body 2 can carry out similarly dwindling or amplifying according to the ability of be suitable for burner.
Further, be also provided with the first pressure valve installing hole on mixture 1, in the first pressure valve installing hole, pressure valve 11 be installed, pressure valve 11 is connected with air gauge.
