Definitions
- the present invention relates to a method for producing coal briquettes which are charged into a base of a molten gasifier in a molten gas production apparatus including a molten gasifier in which reduced iron is charged, and a reducing furnace for providing reduced iron.
- Method for producing coal briquettes according to an embodiment of the step of providing pulverized coal, Mixing a starch, an aqueous acid solution and water to prepare a binder mixture; Mixing the pulverized coal and the binder mixture to produce a coal blend; And forming the coal briquettes by molding the coal briquettes.
- water may be mixed in an amount of 0.01 to 1% by weight and 20 to 60% by weight of an aqueous acid solution of starch, based on 100% by weight of the binder mixture. More specifically, the water may be mixed with 40 to 55% by weight of starch, 0.01 to 0.5% by weight of aqueous acid solution, and the remainder.
- the aqueous acid solution may include at least one citric acid, acetic acid, lactic acid, malic acid, tartaric acid and ascorbic acid.
- 90 to 99% by weight of pulverized coal and 1 to 10% by weight of the binder mixture may be mixed with respect to 100% by weight of coal blend. Specifically, it may include 95 to 98% by weight of pulverized coal and 2 to 5% by weight of the binder mixture.
- the step of preparing the blended coal may include a first mixing step in which mixing is performed at a temperature of 55 to 65 ° C. and a second mixing step in which mixing is performed at a temperature of 65 to 20 (C after the first mixing step. Can be.
- Coal briquettes according to an embodiment of the present invention comprises 1 to 10% by weight of bioplastics, 3 to 15% by weight of moisture and the balance of coal, and bioplastics may be 40% by weight of amylopectin> or less than 60% by weight of amylose. Is done.
- the concentration of the acid aqueous solution may be 1 to 10% by weight. .
- Table 1 summarizes the chemical structures and properties of amylopectin and amylose.
- Step S30 may include a first mixing step of mixing at a temperature of 55 to 65 ° C. and a second step of mixing at a temperature of 65 to 200 ° C. after the first mixing step. 1 again, in step S40, the coal briquettes are manufactured by mixing the pulverized coal and the binder mixture.
- a coal briquette in the form of a pocket or a strip may be manufactured by loading a mixture between the pairs rotating in opposite directions. As a result, coal briquettes having excellent hot strength and hot strength can be produced.
- the char generated by the pyrolysis reaction of the coal briquettes moves to the lower part of the melt gasification furnace 10 and reacts exothermicly with oxygen supplied through the tuyere 30.
- the coal briquettes can be used as a heat source for keeping the melt gasification furnace 10 at a high temperature.
- the left provides air permeability, the reduced iron supplied from the large amount of gas 20 reduction furnace 20 generated in the lower portion of the melt gasification furnace 10 .
- the coal gasification layer 10 in the melt gasification furnace can pass more easily and uniformly.
- a bulk coal material or coke may be charged into the melt gasifier 10 as necessary.
- An air vent 30 is provided on the outer wall of the melt gasifier 10 to blow in oxygen. Oxygen is blown into the coal seam bed to form a combustion zone.
- the coal briquettes may be burned in a combustion zone to generate reducing gas.
- the molten iron manufacturing apparatus 200 includes a molten gasifier 10, a reducing furnace 22, a reduced iron compression device 40, and a compressed reduced iron storage tank 50.
- the reduced reduced iron storage tank 50 can be omitted.
- coal briquettes are fed to the melt gasifier 10 and turned to a breathable left, a large amount of gas and compressed reduced iron generated in the lower portion of the melt gasifier 10 make the coal filling layer in the melt gasifier 10 easier and more uniform. It can be passed through to produce high quality molten iron.
- the storage modulus G '(storage modulus) and loss modulus G "(loss modulus) of each bioplastic are measured according to the pH of the binder mixture, and are shown in FIG. 6.
- Example 2 Viscoelasticity test of bioplastic according to acid type
- the coal briquettes were compressed into a press to produce briquette-shaped coal briquettes having a size of 64.5 mm x 25.4 mm x 19.1 mm.
- the compression strength and the drop strength of the coal briquettes were measured by the following evaluation method.
- the coal briquettes were compressed into a press to produce briquette-shaped briquettes having a size of 64.5 mm x 25.4 mm x 19.1 mm.
- the compression strength and the drop strength of the coal briquettes were measured by the following evaluation method.
- Comparative Example 1 It was prepared from 16 kg coal pulverized coal having an average property and a particle size of 3 kPa or less.
- the coal briquettes were compressed into a press to produce briquette-shaped coal briquettes having a size of 64.5 mm x 25.4 mm x 19.1 mm.
- the compression strength and the drop strength of the coal briquettes were measured by the following evaluation method.
- the coal briquettes were compressed into a press to produce briquette-shaped coal briquettes having a size of 64.5 mm x 25.4 mm x 19.1 mm.
- the compression strength and the drop strength of the coal briquettes were measured by the following evaluation method. Compressive strength test
- the coal briquettes prepared in Experimental Examples 1 and 2 and Comparative Examples 1 to 3 were dropped 4 times or 8 times at a height of 50 m from the ground after 1 hour at room temperature, 24 hours at room temperature, and maintained in a shape of 20 mm or more.
- the weight ratio is expressed as a percentage of the weight of the whole coal briquettes.
- Reduced iron compression device 50 Compressed reduced iron storage tank 100, 200. molten iron manufacturing plant 101. Dome part
