Refined coal is the product of the coalupgrading technology that removes moisture and certain pollutants from lowerrank coals such as subbituminous and lignite (brown) coals, raising their calorific values. Coal refining or upgrading technologies are typically precombustion treatments and processes that alter the characteristics of coal before it is burned.

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 ashforming mineral matter. At present, coal cleaning is accomplished through physical separation of particles low in ...

Ultraclean coal (UCC) from new processing technologies which reduce ash below % and sulfur to very low levels mean that pulverised coal might be used as fuel for very large marine engines, in place of heavy fuel oil. There are at least two UCC technologies under development. Wastes from UCC are likely to be a problem.
