Fuel Cost Savings through Pulverizer Performance Upgrades at the St. Johns River Power Park

摘要

The St. Johns River Power Park (SJRPP) is a two-boiler, 2 × 660 MW station that is jointly owned by JEA (formerly Jacksonville Electric Authority) and Florida Power & Light (FPL). JEA is the plant operator. These Foster Wheeler boilers, started up in 1987 and 1988, were each equipped with 7 OEM vertical spindle pulverizers feeding 28 OEM low NO_x burners in an opposed, wall-fired configuration. Since 2005, the boilers typically fire a blend of 70% Colombian coal (or, to a lesser degree, domestic coal) and 30% delayed petroleum coke.
