Coke (fuel) - Wikipedia

Coal pollution mitigation, sometimes called clean coal, is a series of systems and technologies that seek to mitigate the health and environmental impact of coal; in particular air pollution from coal-fired power stations, and from coal burnt by heavy industry.. The primary focus is on sulfur dioxide (SO 2) and nitrogen oxides (NO x), the most important gases which caused acid rain; and

Coal Reburning Reduces NOx Emissions | Power Engineering

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low
