Abstract

To avoid the fire and explosion danger in the current coking coal moisture control technology, a new coal moisture control technology was proposed in this paper where the superheated steam was used as the drying medium. A self-developed lab scale superheated steam drying experimental setup was constructed and the coal moisture control experiments were carried out. Experimental results showed that the superheated steam can be used as drying medium to reduce the coal moisture from initial 11.9% into the required 6% successfully. Super heated steam temperature,the thickness of coking coal are the key governing parameter in the drying process. Under this experimental condition,when super heated steam temperature increased from 130? to 190?,the drying time of coking coal was shortened from 6min to only 1.5 min. The superheated steam was promising for developing a fast, energy saving coking coal moisture control technology.
