    Abstract: A problem to be solved by the present disclosure is to reduce the emission of undesired pollutants during the combustion of coal. The present disclosure provides a process for treating coal by removing moisture and volatile matter from the coal. Air-borne emissions from the combustion of the fuel product of the invention will be cleaner than those of untreated coal and may obviate post combustion or scrubbing technologies that are typically needed to clean the emissions from a coal-fired burner. The disclosed process provides a less costly solution to the problem of dirty emissions than present techniques. A disclosed process of producing a treated coal and combusting the treated coal involves heating the coal to remove volatiles and drying the product to produce a treated coal consisting essentially of carbon and hydrogen, and combusting the treated coal by introducing a slipstream of natural gas alongside the treated coal in a quantity sufficient to sustain a stable burn in an industrial boiler configured to burn bituminous coals.
