It is a well-known fact that lignite resources cannot be used directly. High moisture, high volatility, low ignition point, and spontaneous combustion, etc., make lignite resources not conducive to transportation and difficult to store. As a result, lignite cannot be sold at a good price in the market, cannot be formed, and it is difficult to enter the market.

  1. Product transportation issues

  The performance is more obvious when the geographical environment is poor or the temperature after the air is low. When the product is transported without a drying process in winter, anti-freezing measures must be taken due to the high moisture content, which will invisibly increase the cost input. Moreover, it is difficult to guarantee the progress of the contention in the export link, and the long-term development goal cannot be achieved.

  2. Excessive moisture content of coal slurry will result in an overall decrease in the calorific value of the blended coal, which will affect the economic benefits of the coal preparation plant

  The moisture in the coal will affect the calorific value of the coal, and it will consume more heat to evaporate the water during the combustion process. Approximately 2.509 MJ of heat is required for each kilogram of water evaporated. Therefore, the high moisture in the coal will reduce the quality of the coal.

  3. The stacking of slime will pollute the environment.

  The surface of the coal slime yard will be weathered under the action of wind and sun. In addition, the coal slime has a very fine particle size, and it will become dusty in windy weather to form a secondary pollution environment.

  Under the situation of increasingly tight energy, the economic value of lignite and its related processing and production technology are paid attention to, and the development of lignite drying and upgrading technology and equipment is the key to clean and effective use of lignite. Zhengzhou Dingli has rich production experience in lignite quality improvement and drying process, which improves heat utilization rate, reduces raw material drying cost, and reduces its smoke and dust content.
