DETAILED DESCRIPTION

[0033] As shown in the figure, the body 1, the air hole 2, the hollow body 3, the support plate 4, the hollow body partition plate 5, the vertical plate 6, the inclined plate 7, the vertical partition plate 8, the horizontal partition plate 9, the outer air exchange hole 10, the air inlet 11. Figure 1 , 10 In one preferred embodiment, the high-efficiency combustion liner comprises a body 1, and a hollow body 3 is arranged in the body 1. Figure 1 In one preferred embodiment, the cross section of the body 1 is oval, and the hollow body 3 is in communication with the combustion area through the air hole 2 on the side wall.

[0034] An air inlet 11 is arranged at the lower end of the hollow body 3, and the gas entering from the air inlet 11 enters the hollow body 3 and is discharged from the hollow body 3 into the combustion area through the air hole 2. In one preferred embodiment, the high-efficiency combustion liner further comprises a support plate 4 supporting the body 1, which can make the body 1 more stably placed in the combustion area. In use, the body 1 can be placed at any position in the combustion area, and one body 1 can be arranged, or two bodies 1 can be arranged symmetrically as shown in the figure, and a main combustion area is arranged between the two bodies 1. Figure 1

[0035] As shown in the figure, the body 1 is a cylindrical body, the hollow body 3 is arranged in the cylindrical body, and the air hole 2 is arranged on the surface of the cylindrical body. In use, the cylindrical body is generally arranged at the center of the combustion area, and multiple cylindrical bodies can also be arranged in the combustion area. Figure 2 As shown in the figure, the body 1 is a cylindrical body, the hollow body 3 is arranged in the cylindrical body, and the air hole 2 is arranged on the surface of the cylindrical body. In use, the cylindrical body is generally arranged at the center of the combustion area, and multiple cylindrical bodies can also be arranged in the combustion area.

[0036] Figure 3 , 4 ​​In options 5 and 6, a hollow partition plate 5 is provided on the inner wall of the outer shell of the main body 1, and a space 3 is formed between the inner wall of the outer shell and the hollow partition plate 5. An air hole 2 is provided on the hollow partition plate 5. Preferably, the hollow partition plate 5 includes a vertical plate 6 and an inclined plate 7 provided on the upper end of the vertical plate 6. The upper end of the inclined plate 7 is inclined towards the center. More preferably, the angle between the inclined plate 7 and the vertical plate 6 is less than 180 degrees.

[0037] Preferably, the upper end of the body 1 contracts inward. Of course, other technologies can also create the effect of the upper end of the body 1 contracting inward. The inward contraction of the upper end of the body 1 can interfere with the gas discharged from the combustion zone because the inward contraction forms a constriction, thereby increasing the gas flow rate.

[0038] like Figure 7 In this case, there are three hollow partition plates 5 inside the main body 1. Generally, they are evenly distributed inside the main body 1, but it is also possible to set one or more plates.

[0039] like Figure 8 , 11 In the process, a hollow body 3 is provided inside the wall of the main body 1, and a vertical partition 8 is provided inside the hollow body 3. Preferably, the vertical partition 8 is parallel to the center line of the main body 1, and the vertical partition 8 forms a gas channel inside the hollow body 3.

[0040] like Figure 9 In the middle, a hollow body 3 is provided inside the wall of the main body 1, and a horizontal partition 9 is provided inside the hollow body 3, which divides the interior of the hollow body 3 into an upper space and a lower space.

[0041] The outer surface of the upper space body 1 is provided with an external ventilation hole 10, and the inner surface of the upper space body 1 is provided with a vent 2.

[0042] The surface of the lower body 1 is provided with air holes 2. This structure has a good effect on the initial stage of combustion, realizing simultaneous air intake from the upper and lower ends.

[0043] In use, two main bodies 1 are placed symmetrically in the combustion zone, which can divide the combustion zone into three parts: left, center, and right. Alternatively, the outer side of the main body 1 can be directly attached to the furnace wall, thereby reducing the size of the combustion zone. Or, only one main body 1 can be placed, or... Figure 3 As shown, one or more hollow partition plates 5 are provided on the inner wall of the main body 1, and air enters from the air inlet 11 and exits from the air hole 2. Figure 1 , 2 The main body 1 shown can be placed in the combustion zone during combustion or before combustion. When the main body 1 is placed, the combustion efficiency is greatly improved. As shown in Figure 3, the structure generally needs to be placed before combustion, which can greatly improve the combustion efficiency.
