Referring to fig. 1 to 7, a fire pan comprises a fire pan body 5, an ash receiving plate 8, a shell 3, a chassis 2, a base 1 and other main components, wherein the top of the fire pan body 5 is provided with an annular edge 51 covered with an annular retaining ring 57, the opening edge thereof is covered with an annular air deflector 7, the bottom thereof is provided with a plurality of leakage holes 52 for allowing burnt furnace ash to pass through, and the side wall of the fire pan body 5 is uniformly provided with a plurality of cyclone inlets 53 extending longitudinally along the circumference, usually, an air guiding cover 54 is arranged at the cyclone inlets 53 for allowing air flow to rotatably enter the inner cavity of the fire pan body 5, the air guiding cover 54 is formed by stamping the side wall of the fire pan body 5 and is made into a single piece with the fire pan body 5, usually, the side wall of the fire pan body 54 is stamped with the inlets 53 and a guiding wall 55 of the inlets, and an upper connecting plate 56 is welded and fixed between the guiding wall and the side wall of the fire pan body 5 to form the air guiding cover 54. The fire pan body 5 is provided with a hollow air inlet cylinder column 6 in the middle, the inlet at the lower end of the air inlet cylinder column 6 is communicated with the space of the base 1, and the upper section of the side wall of the air inlet cylinder column 6 is provided with air outlet holes 61. Usually, a central air hole 57 is formed in the middle of the fire pan body 5, leak holes 52 are distributed at the bottom of the fire pan body 5 around the central air hole, the air inlet cylinder column 6 can be in a round table shape, namely, the diameter of the cylinder column gradually increases from top to bottom, so that the fire pan body 5 is sleeved on the air inlet cylinder column 6 through the matching of the central air hole and the air inlet cylinder column, the lower end of the air inlet cylinder column 6 penetrates through the chassis 2, the lower end inlet of the air inlet cylinder column 6 is communicated with the space of the base 1, usually, a central hole 23 is formed in the bottom surface of the chassis 2, a fixing ring 24 is formed along the central hole 23, the lower end inlet of the air inlet cylinder column 6 is sleeved on the fixing ring 24 and fixed on the chassis 2 and is communicated with the space of the base 1, and a matched ash receiving disc 8 is distributed at the lower end inlet of the air inlet cylinder column 6. In addition, the shell 3 is in a cylinder shape, and the diameter of the shell is larger than that of the fire pan body 5 by one circle, so that the fire pan body 5 is sleeved in the shell 3, an airflow channel is formed between the fire pan body 5 and the shell 3, and the airflow channel is communicated with the cyclone inlet 53. The shell 3 is placed and fixed on the annular baffle plate 22 on the edge of the opening of the chassis 2, so that the fire pan body 5 and the shell 3 are both arranged on the chassis 2, an ash receiving disc 8 is arranged in the middle lower part of the chassis 2 aiming at a leak hole 52 of the fire pan body, the size of the ash receiving disc 8 is usually larger than the diameter of the fire pan body 5, and a central fixing hole 81 is formed in the middle part of the ash receiving disc 8 and sleeved on the air inlet cylinder 6.
