Coal slurry is a waste generated during the coal washing process. Improper handling of it can cause environmental pollution. Due to the high ash and moisture content in coal slurry, it can affect the calorific value of coal slurry. Removing moisture can improve the utilization value of coal slurry. Coal slurry dryer is usually used to remove moisture from coal slurry, therefore, choosing a suitable coal slurry dryer is crucial.
There are two types of coal slurry drying technologies: new and traditional. At present, some users use steam drying to evaporate the moisture in coal slurry. Steam can be generated by steam boilers or by utilizing the waste heat from power plant steam. As long as the temperature reaches a certain level, steam drying will not produce any other exhaust gas, and the amount of dust generated is also very small. If the waste heat from power plant steam is utilized, the cost is very low, sometimes even no cost. Different types of heat sources need to meet the customer's applicable scenarios. If the customer is in an environmentally controlled area, they can also choose a natural gas hot air stove to produce clean hot air during drying, which can reduce the burden of dust removal.
Dingli has carefully developed a new generation of coal slurry drying system based on the market and characteristics of the coal slurry industry. Through multiple technical research and breakthroughs, the moisture content of the dried product is less than 15%, and the calorific value of coal can reach 2800-4200 kcal/kg. It is a good fuel for coal-fired boilers. This set of equipment has mature technology, stable operation, and easy operation and maintenance.welcome to come for consultation!
