Problems solved by technology

Therefore, when briquettes are manufactured using molasses as a binder, the quality of the briquettes cannot be constantly controlled
In particular, when using molasses with high moisture content, there is a problem that the quality of briquettes decreases and the price of molasses continues to rise globally

experiment example

[0064] Production of binder and preparation experiment of pulverized coal

[0065] Alcohol is distilled without the use of ammonia. And, the water content of CMS a was distilled at 50 mPa to 100 mPa to manufacture a binder made of fermented molasses by-product. Here, the fermented molasses by-product binders whose solid contents were 56% by weight and 72% by weight were produced by changing the distillation time.

[0066] In addition, after adjusting the amount of pulverized coal having a particle size of 3 mm or less to 90%, the amount of moisture is adjusted to 6.5% by weight to 9.5% by weight. Moreover, 1-5 weight part of quicklime is added with respect to 100 weight part of pulverized coal, and it mixes for 3 minutes - 10 minutes, and manufactures a mixture.

[0067] Table 3 below shows the composition of the adhesive used in the examples of the present invention. It can be seen that each binder includes components such as C, H, N, S, K, and Na, and also includes organi...

Abstract

The invention provides a manufacturing method of an adhesive used for briquette coal manufactured from molten iron. The method includes following steps: i) mixing molasses and water to obtain a mixture; ii) adding an acid into the mixture; iii) adding culture bacteria into the mixture to ferment the mixture; and iv) distilling the mixture to remove alcohol.

Description

technical field [0001] The invention relates to a method for manufacturing a binder for briquette coal and a method for producing briquette coal including the binder. In more detail, it relates to a method for producing a binder for briquettes that is a by-product of fermentation molasses (condensed molasses solubles, CMS), and a method for producing briquettes including the binder. Background technique [0002] In the smelting reduction ironmaking method, a reduction furnace for reducing iron ore and a melter-gasifier for melting the reduced iron ore are used. When the iron ore is melted in the melter-gasifier, briquettes are charged in the melter-gasifier as a heat source for melting the iron ore. Here, after the reduced iron is melted in the melter-gasifier, it is converted into molten iron and slag and discharged to the outside. The briquettes charged into the melter-gasifier form a packed bed of coal. Oxygen is blown in by a blower installed in the melter-gasifier, a...
