Those skilled in the art can readily appreciate other advantages and functions of the present disclosure from the disclosure herein. In addition, the present invention may be implemented or applied by various other specific embodiments, and various modifications and changes may be made without departing from the spirit of the invention.

Please refer to FIG. 1 to FIG. 3 , FIG. 1 is a schematic diagram of a system for preparing a combustion improver according to an embodiment of the present invention; FIG. 2 is a block diagram of a system for preparing a combustion improver according to an embodiment of the present invention; Another block diagram of a system for preparing a combustion improver.

As shown in FIG. 3, in the converter steelmaking process, by-products of molten steel and converter dust 12 are generated. As shown in FIG. 1, the present embodiment is a combustion-producing system 1 which may include a converter dust. The recovery device 10, a dewatering device 20, a combustion device 30, and a stirring device 40. As shown in FIGS. 1 and 2, first, the converter dust recovery device 10 can recover a converter dust 11 via a wet process to produce a converter dust sludge 12. Next, the dewatering apparatus 20 may dehydrate the converter dust 12 to produce a mud cake 21 comprising 40 wt% to 70 wt% of iron oxide, 10 wt% to 30 wt% of calcium oxide, and 20 wt% to 40 wt%. Water. Further, the combustion device 30 may be provided with a fuel 31 to which 0.1% by weight to 0.0001% by weight of the mud cake 21 is added relative to the total weight of the fuel 31. Further, the agitating device 40 may mix and mix the mud cake 21 and the fuel 31; wherein 0.1% by weight to 0.0001% by weight of the mud cake 21 serves as a oxidizer 21' in the fuel 31.

As shown in FIG. 2, after the mud cake 21 is produced, a first combustion step can be performed in the combustion device 30, in which the fuel 31 reacts to form a nitrogen oxide 301, a sulfur oxide. 302, a hydrocarbon 303 or a suspended particle 304. After the mud cake 21 and the fuel 31 are mixed and stirred, a second combustion step may be performed in the combustion apparatus, the combustion step including a reaction temperature in a temperature range of 200 ° C to 700 ° C. When the reaction temperature is between 400 ° C and 500 ° C, the Fe ^{3+ on the} surface of the iron oxide is reduced to Fe ²⁺ via carbon monoxide, and the Fe ^{2+ is further} reduced to a nitrogen gas to reduce the nitrogen oxide.
