Petcoke may be combusted as fuel in industrial and power generating plants. Cement plants and power plants are currently the two greatest consumers of petcoke. There is some limited use as space heating and in commercial brick kilns in Europe, and a small but emerging market as a metallurgical coal blending component for the steel industry.
Petroleum coke is commonly used in CFBC plants, a low volatile fuel not well suited for use in PC plants (Anon., 2010). However, it commonly has a high sulfur content (as indicated in Table ) so the limestone feed and ash removal systems must be designed for higher flow rates than for a CFBC plant firing lowsulfur PRB coal.
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.
