The shape of the air inlet and outlet pipe 300 can be selected according to the actual situation, such as a rectangular hollow pipe or a cylindrical hollow pipe. The burner 400 is installed on the upper part of the air inlet and outlet pipe 300. The burner 400 is used to block the upper part of the air inlet and outlet pipe 300, so that the air is blown out from the air outlet hole on the side wall of the air inlet and outlet pipe 300 into the furnace body 100, and disperses the gasified fuel above it to make the combustion more complete. The fan 500 is connected to the air inlet and outlet pipe 300 and supplies air through the fan 500.

[0040] In this embodiment, the required fuel, such as waste engine oil, recycled oil, diesel, etc., is transported to the furnace body 100 through the oil supply pipe 200. Then, the igniter is lit and placed into the furnace body 100 to ignite the fuel. At the same time, air is supplied by the blower 500. The air enters the air supply pipe through the air inlet 310 of the air supply pipe 300 and then exits into the furnace body 100 through the air outlet of the air supply pipe, gasifying the fuel and providing the oxygen required for combustion.

[0041] In a preferred embodiment, a first control switch 600 is also included. The first control switch 600 is connected to the fan 500.

The two outlet ends of the oil supply pipe 200 are located on one side and the opposite side of the furnace body 100, respectively. With this arrangement, when the oil supply pipe 200 supplies fuel to the furnace body 100, the fuel can be distributed more evenly in the furnace body 100, resulting in more complete combustion. It should be noted that the number of outlet ends of the oil supply pipe 200 connected to the furnace body 100 in this embodiment is not a limitation of this utility model. It can be selected according to the actual situation, and the outlets of the oil supply pipe 200 can be evenly distributed on the furnace body 100.

[0044] In a preferred embodiment, the air outlets on the air inlet and outlet duct 300 include at least one lower air outlet 321 near the bottom of the air inlet and outlet duct 300 and at least one upper air outlet 322 near the top of the air inlet and outlet duct 300. In this embodiment, three lower air outlets 321 are provided near the bottom of the air inlet and outlet duct 300, evenly distributed on the bottom sidewall of the air inlet and outlet duct 300. The lower air outlets 321 are mainly used to gasify the fuel at the bottom of the furnace body 100; the upper air outlets 322 are located near the top of the duct. The upper air outlet 322 of the part has 20 openings, which are evenly distributed on the top side wall of the air inlet and exhaust pipe 300. The upper air outlet 322 is mainly used to provide oxygen to the furnace body 100, and at the same time blow the gasified fuel to the bottom of the burner 400 to improve the combustion efficiency. It should be noted that in this embodiment, the number of lower air outlets 321 opened near the bottom of the air inlet and exhaust pipe 300 and the number of upper air outlets 322 opened near the top of the air inlet and exhaust pipe 300 can be selected according to actual needs.

[0045] In a preferred embodiment, the system also includes an oil storage tank 800, which has an oil outlet 810 and a second control switch 820. The oil outlet 810 is located above the inlet end of the oil pipeline 200. The second control switch 820 is used to control the opening and closing of the oil outlet 810 and to control the amount of oil delivered by the oil outlet 810. The second control switch 820 can be selected as a knob switch, a lever switch, or a push-pull switch, etc., according to actual needs. The oil storage tank 800 has an oil inlet 840 at the top for refueling. The oil inlet 840 is equipped with an openable cover 850 to prevent external dust particles and impurities from entering the oil storage tank 800, causing blockage or affecting the combustion effect.

The furnace body 100 is located on one side of the partition 910 inside the furnace frame 900, and the blower 500 and power supply 700 are located on the other side of the partition 910 inside the furnace frame 900. The partition 910 is filled with heat-insulating material, or the partition 910 is made of heat-insulating material, which can prevent the heat from combustion inside the furnace body 100 from affecting the blower 500 and power supply 700 during use, reducing their service life, or even causing them to malfunction or be damaged. The oil storage tank 800 is installed on the outside of the furnace frame 900 for easy refueling by the user.

[0048] In a preferred embodiment, the bottom of the oil storage tank 800 on the side away from the oil outlet 810 is at a higher level than the bottom of the side of the oil storage tank 800 near the oil outlet 810. This causes the fuel in the oil storage tank 800 to flow towards the side of the oil storage tank 800 near the oil outlet 810, improving fuel utilization. The oil storage tank 800 is detachably connected to the furnace frame 900, making it convenient for users to remove the oil storage tank 800 to add fuel or to clean the inside of the oil storage tank 800.

[0049] As a preferred implementation, to achieve a higher horizontal height on the side of the oil storage tank 800 furthest from the oil outlet 810 than on the side closest to the oil outlet 810, two support columns 830 can be installed on each side of the bottom of the oil storage tank 800, and two mounting slots 920 can be provided on the outside of the furnace frame 900. The two support columns 830 are placed in the mounting slots 920 for detachable connection. By using two support columns 830 of different lengths, with the support column 830 closer to the oil outlet 810 of the oil storage tank 800 being the shorter one, the height difference between the two sides can be achieved; alternatively, two mounting slots can be used. The mounting grooves 920 have different depths, with the mounting groove 920 on the side closer to the oil outlet 810 of the oil storage tank 800 being deeper, thus achieving a height difference between the two sides of the bottom of the oil pipe. It should be noted that in this embodiment, there is no restriction on the method of setting the bottom of the oil tank on the side away from the oil outlet 810 to be higher than the bottom of the oil storage tank 800 on the side closer to the oil outlet 810. Alternatively, mounting grooves 920 can be opened on both sides of the bottom of the oil storage tank 800, and two support frames 930 can be set on the outside of the furnace frame 900. The height difference between the two sides of the bottom of the oil pipe can be achieved by using the different depths of the mounting grooves 920 on both sides or the different lengths of the two support frames 930.

[0050] In a preferred embodiment, the furnace frame 900 is provided with a support frame 930, which is located on the upper part of the furnace body 100 and is used to place the pot.

[0051] In a preferred embodiment, the furnace frame 900 is provided with heat dissipation holes 940 on the outside. The heat dissipation holes 940 are located on the side of the furnace frame 900 near the fan 500 and the power supply 700.
