It refers to a thermal power device that releases heat through the combustion of coal in the furnace, heating the heat medium water or other organic heat carriers (such as thermal oil, etc.) to a certain temperature (or pressure). The coal burned as fuel, after the heat of the coal is converted, produces steam or becomes hot water, but not all the heat is effectively converted, and some of it is consumed as reactive power. A coal-fired boiler refers to a combustion device.
[0003] The coal-fired boiler has a square shape and mainly burns coal to burn objects. The internal space of the combustion device is limited.

After the combustion box 10 moves to the outside, the staff can put the objects that need to be burned into the combustion box 10. Then, after starting the servo motor 3, it will drive the gear 4 to rotate, thereby driving the two straight racks 7 meshing with it to move left and right. When the two straight racks 7 move relative to each other, they drive the two combustion boxes 10 to be gradually loaded into the interior of the combustion box 1. Subsequently, the two discharge plates 16 are respectively connected to the two The discharge ports 15 are engaged with each other, the push-pull plate 13 is engaged with the combustion box 1, and the combustion box 1 is sealed. The flame of the coal burning can contact the placed objects through the multiple leakage holes 11 to achieve the combustion effect. The structure can solve the problem of artificially pushing the combustion box 10, and objects can be stored in the two combustion boxes 10 at the same time, which increases the use range of the combustion device. The structures arranged inside the combustion box 1 are all made of high-temperature resistant materials and have good high-temperature resistance. When the gear 4 is engaged with the straight rack 7, the adjustment block 6 can move at one end of the adjustment rod 5, and the vertical plate 9 is connected to the adjustment block 6 by the vertical rod 8. Therefore, the position of the combustion box 10 inside the combustion box 1 can be adjusted by moving the adjustment block 6. When the straight rack 7 moves toward each other, the two combustion boxes 10 are respectively moved to the two sides outside the combustion box 1. At this time, the discharge plate 16 and the discharge port 15 are separated from each other, which is convenient for the staff to put objects into the combustion box 10 for subsequent combustion.
