Introduction to a high-capacity low-rank coal dewatering and upgrading technology that has been in normal operation for 1 year

Thread Content

1. Features: 1) It has been in operation at full capacity for one year and is still producing normally； 2) High processing capacity: 350 tons of low-grade coal can be processed per hour; 3) Quasi-static fluidized drying, resulting in virtually no generation of secondary coal dust ； 4) All core equipment is imported from abroad, allowing the system to achieve true airtight conditions for drying in a low-oxygen environment, thereby ensuring the safe operation of the system ； 5) Emissions meet environmental standards; environmental inspection has been passed ； 6) Although all the core equipment is imported from abroad, due to the large volume of processing, the investment per ton of coal is similar to that of other domestic processes ； 2. Applications: 1) When low-grade coal is treated using this technology to remove water at a large scale and at low cost, thereby increasing its calorific value, it can be sold directly, which boosts the added value and sales volume of coal products ； 2) After using this technology to remove moisture from coal products on a large scale at low cost for low-rank coal, it improves the quality of the raw coal used in subsequent processes such as coal carbonization and gasification ； The above is a brief overview; we welcome colleagues who are actually involved in production, operation, and process design in this field to engage in technical discussions!
