Can coking coal drying be preheated by power plant steam or with heat transfer oil? Steam dryers are widely used in coal, slag, feed and other fields, and the technology is mature, and it is feasible to use steam for coking coal dryers. Not only coking coal such as blue charcoal, bituminous coal, lump coal, pulverized coal and many other coals can use steam dryers.
Feasibility of using steam for coking coal dryer
Steam with a temperature above 100 degrees first enters the tube converter for technical treatment to reach the heat and temperature required for coking coal drying, and meet the evaporation intensity per unit area of the coking coal dryer. The coking coal with large water content is evenly heated through the steam tube. , Quickly evaporate water to meet the drying requirements.
The use of steam dryers for coking coal dehydration and drying has advantages in environmental protection and cost. Steam waste heat is a waste resource. During the entire steam drying process of coking coal, due to the good sealing performance of the steam dryer, the dust content in the exhaust gas is low. , The work load of the dust collector is small, the bag renewal rate is low, and the maintenance cost is reduced. Therefore, the cost of using steam to dry the coking coal is lower.
