A number of heat dissipation fins 11 are fixedly installed on the outside of the heat dissipation rod 9 near the top and bottom. Through this arrangement, the heat conducted out of the heat-conducting block 7 can be dispersed on multiple heat dissipation rods 9 and multiple heat dissipation fins 11, and the heat is distributed to avoid concentrated action on the water-cooled wall body 2, which accelerates thermal corrosion and aging of the water-cooled wall body 2.

[0025] See also Figure 2 and Figure 4 The plurality of heat dissipation fins 11 are bent outwards, and the bent heat dissipation fins 11 increase the contact surface and improve the heat conduction effect.

[0029] Working principle: When the present application is in use, the furnace body 1 is first used normally to work. During this period, the water-cooled wall body 2 arranged inside the furnace body 1 is used to absorb the heat of the flame in the furnace, protect the furnace wall, prevent slagging of the furnace wall and the heating surface, simplify the furnace wall structure, and reduce the weight of the furnace wall. In addition, through the cooperation of the wear-resistant shell 3 and the wear-resistant sleeve 4, the wear-proof and wear-resistant treatment of the inside of the water-cooled wall body 2 is achieved, and the service life of the water-cooled wall body 2 is improved.
