insufficient contact with the oxygen when the fuel is combusted, and the combustion efficiency of the fuel is ensured, when the coal powder is used as the fuel, because the density between the coal powder is large and the gap is small, the coal powder at the upper end is completely combusted, and the coal powder at the lower end cannot be combusted is avoided, when the coal powder is added on the fire grate 12 to be combusted, the coal powder is driven to pass through the first hollow-carved 13 along with the movement of the fire grate 12, and is raked by utilizing the rods 25 on the first hollow-carved, the coal powder at the lower end is exposed to ensure sufficient combustion of the coal powder, then the coal powder moves to the second hollowed-out area 14, the coal powder is raked for the second time by utilizing the rake rods 25, the contact between the coal powder at the lower end and oxygen is further improved, meanwhile, the rake rods 25 on the first hollowed-out area 13 and the second hollowed-out area 14 are arranged in a staggered mode, the rake rods 25 are in a triangular column shape, the situation that the coal powder is blocked by the rake rods 25 and cannot move along with the grate 12 due to the fact that the coal powder is poked at different positions, the dispersion rate of the coal powder is improved, when the coal powder is in contact with the first hollowed-out area 13 and the second hollowed-out area 14, the scraper 24 at the lower end, where the first hollowed-out area 13 is in contact with the second hollowed-out area 14, scrapes the coal grate 12 and the coal powder, the heated coal powder is prevented from being adhered to the grate 12, when the coal is used as a fuel, the coal is conveyed to the grate 15 after being combusted on the coal 12, the coal ash after combustion directly passes through the first coal filtering hole 21 and the second coal filtering hole 22 on the grid 15 and falls into the slag discharging bin 9 to be discharged, the unburned coal is blocked to be continuously combusted, the situation that the unburned coal is completely and directly discharged to cause resource waste is avoided, then the driven shaft 11 rotates, the shifting plate 17 on the driven shaft 11 shifts the fire grate 12, so that the grate 12 is lifted up and down near the end of the grate 15, the grate 12 pushes the second partition 20 upwards inside the first partition 19, the first coal filtering holes 21 and the second coal filtering holes 22 are staggered with each other, the first coal filtering holes 21 and the second coal filtering holes 22 are prevented from being blocked by coal, the grid 15 can be ensured to normally carry out coal filtering operation, the heat generated after the fuel is combusted heats the water in the furnace barrel 3, thereby converting the heat energy into steam energy, and the flue gas generated by the fuel combustion is discharged through the smoke discharge pipe 8 for further treatment.
