[0002] Fixed grates usually have a fixed ventilation structure and cannot be flexibly adjusted according to combustion requirements. This results in unsatisfactory ventilation effects under certain combustion conditions, affecting the full combustion and combustion efficiency of the fuel. In addition, the ash generated in the furnace barrel is prone to accumulate in the ventilation channel, causing blockage, which not only affects air circulation, but may also cause damage to the grate and furnace barrel, reducing the service life of the equipment.

[0014] like Figure 1-5 As shown: an adjustable grate, including a furnace drum 1, an ash discharge port 2 is opened at the bottom of the front side wall of the furnace drum 1, and a furnace door 3 is rotatably connected to the upper edge of the ash discharge port 2. The furnace door 3 is adapted to the ash discharge port 2. There are several fixed slats 4 in the furnace drum 1, and the fixed slats 4 are located above the ash discharge port 2. The fixed slats 4 are equidistantly distributed on the left and right. The front and rear ends of the fixed slats 4 are fixedly connected to the front and rear inner walls of the furnace drum 1. Long strip holes 5 are formed between adjacent fixed slats 4. The width of the long strip holes 5 is equal to the width of the fixed slats 4. A limiting plate 10 is provided below the fixed slats 4. The limiting plate 10 is frame-shaped and is in close contact with the furnace drum 1. The inner wall is fixedly connected, the limiting plate 10 is clearance-matched with the fixed strip 4, and there is a furnace bottom plate 6 between the limiting plate 10 and the fixed strip 4. The furnace bottom plate 6 passes through the left side wall of the furnace barrel 1, and the furnace bottom plate 6 is clearance-matched with the left side wall of the furnace barrel 1. The furnace bottom plate 6 slides with the limiting plate 10, and the furnace bottom plate 6 slides with the fixed strip 4 and the furnace barrel 1 respectively. The left end of the furnace bottom plate 6 is fixedly connected with an anti-scalding handle 7. Several ash holes 8 are provided on the top of the furnace bottom plate 6. The width of the ash holes 8 is the same as the width of the long strip holes 5. Ventilation holes 9 are provided on the rear side wall and the right side wall of the furnace barrel 1, and the ventilation holes 9 are located below the limiting plate 10.

[0015] In the initial state of the adjustable grate, the furnace bottom plate 6 is installed between the limit plate 10 and the fixed strips 4, and the ash holes 8 on the furnace bottom plate 6 are aligned with the long strip holes 5 between the fixed strips 4, forming a certain ventilation channel. At this time, the furnace bottom plate 6 is fixed in the furnace tube 1 by the anti-scalding handle 7 at its left end, which is convenient for pulling and preventing burns to the operator.

[0016] When the ventilation effect in the furnace needs to be adjusted, the operator can hold the anti-scalding handle 7 and pull the furnace bottom plate 6 to the left. As the furnace bottom plate 6 moves, the alignment degree between the ash drop hole 8 and the long hole 5 will change, thereby changing the size of the ventilation channel.

[0017] During the combustion process, ash is generated in the furnace tube 1, which can be discharged through the ash discharge port 2. However, in some cases, the ash may block the ventilation passage. At this time, the operator can pull the furnace bottom plate 6 to change the alignment of the ash drop hole 8 and the long hole 5, so that the ash can more easily fall into the ash discharge port 2 through the ventilation passage, thereby preventing blockage.
