Coal is regarded as the most environmentally hazardous one. An advanced solution to the environmental problems of coal-burning enterprises is switching from coal to fuel slurries containing water and waste flammable liquids. These are known as coal-water slurries (CWS) or coal-water slurries containing petrochemicals (CWSP).The powder is burned in a combustion chamber by entraining the particles in combustion air. Because finely ground coal has more surface area per unit weight than larger particles, the combustion reactions occur at a faster rate, thus reducing the time required for complete combustion to about 1 to 2 seconds. ...

The study results of ignition of organic coal-water fuel (OCWF) compositions were considered. The main problems associated with investigation of these processes were identified. Historical perspectives of the development of coal-water composite fuel technologies in Russia and worldwide are presented. The advantages of the OCWF use as a power-plant fuel in …In addition to being used as an energy source, coal also has significant potential for other, more sustainable uses including water treatment. In this study, we present a simple approach to treat water that was produced during oil production and contained a total dissolved solids (TDS) content of over 150 g/L using Powder River Basin (PRB) coal. PRB coal used …
