Abstract
Most coal requires some preparation before use. Preparation may range from simply crushing to provide a size consist suitable for certain types of boilers to extensive size reduction and cleaning to remove sulfur and ash-forming mineral matter. At present, coal cleaning is accomplished through physical separation of particles low in mineral content from particles high in mineral content. In the future it may include chemical and biological treatment for removal of certain impurities from coal. In this chapter, the present state of the art of coal cleaning and promising new technological developments will be reviewed. Attention will also be given to problems requiring further research and development.
Ames Laboratory is operated for the U.S. Department of Energy by Iowa State University under Contract No. W-7405-Eng-82.
