[0016] As shown in FIG. 1 to FIG. 3, the present disclosure provides a gasifier with a tornado flame effect and capable of forming a web flame, which includes a cylindrical outer shell 2 and a furnace core 4 provided in the outer shell 2, wherein the furnace core 4 includes a carbon bridge 41 and a secondary combustion enclosure 42 connected to the carbon bridge 41. The carbon bridge 41 is fixedly connected with the outer shell 2 through a carbon bridge fixing frame 3, and a cavity a is formed between the secondary combustion enclosure 42 and the outer shell 2. The carbon bridge 41 is provided with a plurality of vent holes 411, the lower part of the outer shell 2 is provided with a plurality of air inlet holes 221, and the upper edge of the secondary combustion enclosure 42 is provided with a plurality of air outlet holes 421, which are obliquely arranged at the same angle in the same direction. The air inlet holes 221 are communicated with the air outlet holes 421 through the cavity a. In the height direction of the secondary combustion enclosure 42, the air outlet holes 421 form at least one layer of concentric circular structure. On the concentric circular structure of each layer, the plurality of air outlet holes 421 are uniformly distributed on a circumference, so that the upper part of the secondary combustion enclosure 42 forms a tornado rotating flame effect with unidirectional vortex.

[0017] As shown in figs. 2 and 4, the secondary combustion enclosure 42 includes a secondary combustion enclosure inner wall 422 and a secondary combustion enclosure outer wall 423. The air outlet holes 421 are provided on the secondary combustion enclosure 42 and can be subdivided into an air outlet hole left end 4211 and an air outlet hole right end 4212. In this embodiment, the air outlet hole left end 4211 is recessed toward and protruded from the secondary combustion enclosure outer wall 423, and the air outlet hole right end 4212 is recessed toward and protruded from the secondary combustion enclosure inner wall 422. Two rows of vent holes 421 are arranged on the secondary combustion enclosure 42, and these vent holes 421 are provided in an inclined manner. In practical application, the flame is guided and ejected through the air outlet hole 421, forming a flame network (as shown in FIGS. 5 and 6) in the form of counterclockwise vortex in the northern hemisphere (as shown in the circular track in FIG. 4).

[0018] In other embodiments, the air outlet hole 421 on the secondary combustion enclosure 42 is configured such that the air outlet hole left end 4211 is recessed toward and protruded from the secondary combustion enclosure inner wall 422, and the air outlet hole right end 4212 is recessed toward and protruded from the secondary combustion enclosure outer wall 423. This arrangement enables the flame to be ejected from the air outlet hole 421 to form a clockwise vortex in the southern hemisphere (not shown).

[0019] As shown in FIG. 4, in a direction from along the top end of the secondary combustion enclosure 42 towards the bottom end of the secondary combustion enclosure 42, that is, viewed from top to bottom, a plurality of air outlet holes 421 are arranged obliquely at the same angle counterclockwise, and the angle is 3-10 degrees. In the height direction of the secondary combustion enclosure 42, a plurality of air outlet holes 421 form a two layers of concentric circular structures, and the positions of the air outlet holes 421 on the two layers of concentric circular structures are staggered. A necking 222 is formed at the upper end of the outer shell 2, and the necking 222 limits the secondary combustion enclosure 42 at the upper end. A positioning groove 223 is also formed at the necking 222, which is used for placing the flame hood 5, so that the flame can be further gathered towards the center. The carbon bridge 41 and the secondary combustion enclosure 42 are connected by welding after insertion. Specifically, the carbon bridge 41 is provided with an insertion hole, and the lower end of the secondary combustion enclosure 42 is provided with an insertion part for receiving the insertion part. The carbon bridge fixing frame 3 is welded with the outer shell 2, and the carbon bridge fixing frame 3 is bolted with the carbon bridge 41. The outer shell 2 is divided into two parts: a main shell 22 and a base 21. The air inlet holes 221 are formed on the main shell 22, and the base 21 is detachably connected to the lower part of the main shell 22. The accumulated dust generated by combustion leaks and deposits in the base 21 through the vent holes 411, and the accumulated dust can be conveniently discharged by the way of back-fastening. Support feet 1 are fixed at the lower part of the base 21.

[0020] This gasifier adopts a cylindrical overall design, and an inclined air outlet 221 is designed at the top of the secondary combustion enclosure 42. This design not only ensures the sufficiency of secondary oxygen supply, promotes the complete combustion of fuel, but also realizes the visual effect of tornado rotating flame, which is both beautiful and ornamental, and meets the application requirements of diversified scenes. The product design is elegant, the assembly is convenient and quick, the thermal efficiency is high, and the smoke is less, which is beneficial to improving the customer's product experience.
