REFUSE DERIVED FUEL USING PULVERIZED COAL AND PRODUCTION METHOD THEREOF
Technical Field
[I] The present invention relates in general to refuse derived fuel using pulverized coal (or coal dust) and a production method thereof. More specifically, the present invention provides a solid fuel having pulverized coal as a primary ingredient mixed with a variety of additives to offer excellent performance, so that hard-to-recycle materials such as pulverized coal can be recycled more efficiently and, at the same time, the solid fuel can be utilized as an alternative fuel for the lump coal excellent in product performance.
[2]
Background Art [3] As is well known, iron manufacturing companies in general undertake a variety of processes to produce steel. [4] The production of steel is largely divided into an iron-making process, a smelting process, and a rolling process. Here, the iron-making process is a basic process for preparing molten steel, where mainly iron ore and coking coal (hard coal) are fed into a blast furnace and preheated blast air of approximately 12000C is blown into the furnace to burn the coking coal, while generating heat. [5] The generated heat is then used to melt down the iron ore to molten steel, which is also called molten iron rich in carbon and impurities such as sulfur. [6] Using lumps of coal as coking coal is not a big problem, except that the lump of coal is expensive and has a limited yield so it is rather urgent to develop a new alternative fuel. [7] In general, when coal (hard coal) is mined from the earth, 10-15% of the coal is in the form of a lump and the rest is in the form of powder. [8] Pulverized coal that is mined together with lump coal amounts to roughly 20,000,000 tons each year, and it is easily carbonized and burns without smoke. [9] The pulverized coal consists of a low content of volatile matters at an amount of
3-7% by weight and a high content of fixed carbon at an amount of 80-90% by weight.
Accordingly, the pulverized coal is burned giving off short sparks and no smoke. [10] In addition, having the ignition point at approximately 4900C, the pulverized coal does not readily ignite, but the coal-fired power is very strong and the coal burns continuously, maintaining a constant temperature.
[I I] On the other hand, the lump coal contains a large amount of volatile matters so it
produces flame while burning. Peat, lignite, brown coal, bituminous coal, etc. are all classified as the lump coal.
[12] The lump coal is high in heating value and demonstrates excellent performance as a product in diverse applications such as electricity generation, while the pulverized coal is low in heating value and shows the limited applicability.
[13] Meanwhile, there is briquette produced by mixing molasses, starch and the like with pulverized coal to enhance the cohesive force. However, the briquette is found utile only at normal temperature, but it is deformed being incapable of overcoming high temperature effects, raising many questions in its applicability range.
[14] Therefore, raw materials had to be imported from abroad as a substitute for the pulverized hard coal, so a lot of money has to be spent for material cost and the applicability range of the domestically obtained pulverized coal has been decreased.
[15] Meanwhile, some brickyards in rural areas use a brick press system to make bricks, but the marketability of bricks has dropped relative to the output capability, so a good part of the brickyards stop their business or suffer much loss.
[16] However, if the solid fuel containing pulverized coal according to the present invention can be produced with the brick press system available at the brickyard, it is advantageous for not only its utilization of pulverized coal but also the enhancement of the yield of the brickyard.
[17]

[19] Another object of the present invention is to press mold the mixture so as to form a single unit object.
[20]

[21] To achieve the objects and advantages of the invention, there is provided a mixture comprising pulverized coal as a primary ingredient and cement as an additive, with a mixed ratio for pulverized coal: cement being 100: 7-12 percent by weight.
[22] Another aspect of the present invention provides a mixture comprising pulverized coal as a primary ingredient and cement and petro cokes as additives, with a mixture ratio of pulverized coal: cement: petro cokes being 100: 7-12: 12-30 percent by weight.

[24] Another aspect of the present invention provides a mixture comprising pulverized coal as a primary ingredient and cement and a combustion agent as additives, with a mixture ratio of pulverized coal: cement: combustion agent being 100: 7-12: 0.0001-1.5 percent by weight.

[32]
Brief Description of the Drawings
[33] The above and other objects and features of the present invention will become apparent from the following description of the preferred embodiments given in conjunction with the accompanying drawings, in which:
[34] FIG. 1 is a flow chart using a block diagram for describing a production method of refuse derived fuel in accordance with the present invention; and
[35] FIG. 2 shows refuse derived fuel manufactured in accordance with the present invention method.
[36]
Mode for the Invention
[37] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[38] FIG. 1 is a flow chart using a block diagram for describing a production method of refuse derived fuel in accordance with the present invention, which the method includes five steps from Sl through S5 as shown.
[39] Pulverized coal retains a heating value of approximately 5,000 Kcal, and a mixture of the present invention is prepared by adding special additives to pulverized coal to improve the heating value and the adhesiveness of the pulverized coal that functions as a primary ingredient.
[40] For example, petro cokes high in heaving value is added to pulverized coal, the primary ingredient, as part of the additives.
[41] Because petro cokes being added retain a heating value of approximately 8,500 Kcal, the mixture of pulverized coal and petro cokes can provide a heating value of approximately 6,000 Kcal in total.
[42] In order to produce a predetermined refuse derived fuel by mixing pulverized coal and petro cokes, cement and clay are also added as additives to reinforce a bonding force and facilitate the production of refuse derived fuel.
[43] Moreover, a small amount of combustion agent is further added as a catalyst to yield a more complete combustion.
[44] The composition ratio of the primary ingredient and other additives is now described below.
[45] Added to 68-81.99% by weight of the pulverized coal are 10-20% by weight of petro cokes, 6-8% by weight of cement, 2-3% by weight of clay, and 0.01-1% by weight of the combustion agent.
[46] With respect to 100% by weight of pulverized coal as a primary ingredient, additives that consist of 7-12% by weight of cement, 12-30% by weight of petro cokes, 2-5% by weight of clay, and 0.0001-1.5% by weight of the combustion agent are added to obtain the pulverized coal mixture. The weight ratio by percent can be varied
depending on the mixture ratio of the pulverized coal to the additive(s) including cement.
[47] By increasing heating value of the pulverized coal as described above, it becomes possible to produce refuse derived fuel high in heating value.
[48] Furthermore, the refuse derived fuel of the invention can be produced with the brick press system used for making bricks at the brickyard.
[49] FIG. 2 illustrates refuse derived fuel that is obtained in accordance with the production method of the present invention. Besides the shape shown in the drawing, the refuse derived fuel may take various angled shapes and sizes according to the press system used.
[50] While the present invention has been described with respect to certain preferred embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims. Industrial Applicability
[51] As for refuse derived fuel using pulverized coal in accordance with the present invention, first, low heating value pulverized coal is mixed with petro cokes to produce refuse derived fuel of high heating value. Then, a place like an iron works may conveniently utilize such high heating value coking coal as a substitute.
[52] In addition, by producing refuse derived fuel of the present invention with the brick press system available at the brickyard, yield of the small and medium sized brickyards suffering poor yield can be increased, thereby achieving other synergy effects, i.e. social economy is activated and competitive power among the small and medium sized companies is improved.
