The petroleum coke fired CFB boilers technology selection allowed the investors to utilize local fuel or sorbent sources significantly lowering the . operational cost of the plants. Petcoke-fired boilers typically have a multi-fuel design where a blend of coal and petroleum coke may vary in different proportions.
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 13.5) so the limestone feed and ash removal systems must be designed for higher flow rates than for a CFBC plant firing low-sulfur PRB coal.
