Definitions
- the present invention relates to a coal supply apparatus for reducing and dispersing and supplying dust of coal input for drying in a coal drying apparatus using reheat steam, and more particularly, in a multi-stage dryer for drying coal using reheat steam.
- the present invention relates to a device for minimizing dust generation when feeding coal to a multi-stage dryer from a coal feeder through a differentiator and dispersing coal to a transport device.
- coal-fired coal-fired power plants burn about 180 tonnes / hr of coal per 500 MW, and supply about 37 tonnes of coal to the boiler per quarter.
- the coal-fired 500-MW coal-fired power plant has approximately six 500 tonnes of coal storage, five of which are supplied with normal coal, and one reserve reserves for use over a period of time. It is operated by low coal.
- the standardized design criteria for coal is 6,080 Kcal / Kg and less than 10% low moisture bituminous coal.
- Some coal-fired power plants use imported coal, some of which have a mean water content of more than 17%, which reduces the combustion efficiency of the boiler. If the calorific value of coal used at the standardized combustion limit of 5,400 Kcal / Kg is low, the generation efficiency and fuel consumption are expected to decrease due to lower combustion efficiency.
- sub-bituminous coal which is a low-molecular coal with high moisture content, the water content is higher than the design standard, and the transfer system for transporting coal is not smooth. In some cases, however, the heat distribution in the boiler may be drift and operate in an abnormal state.

- the surface moisture is mostly water sprayed during the washing process and transportation and storage in the mountain area, and the amount is determined according to the surface area and absorbency. The smaller the particles, the larger the surface area and the formation of capillaries between the particles. This increases the moisture content.
- the combined moisture is formed in the coal generator, and is followed by lignite, bituminous coal (bituminous coal, sub-bituminous coal) and anthracite. If the coal has a lot of moisture, the calorific value is lowered and the transportation cost is increased, so it is necessary to control the moisture in the process of mixing, crushing and separating coal.
- coal is fed from a multi-stage dryer, ie, a conveyor with a plurality of through holes through which reheat steam passes, or a conveying plate combined with a plurality of combined conveying plates while spraying hot reheat steam under the dryer to dry coal.
