The Florida Department of Environmental Protection on Nov. 9 granted a final air construction permit that allows the firing by JEA of up to 240 tons per day of biomass for each of the Northside Generating Station Boiler Nos. 1 and 2.
The new permit also revises the description of St. Johns River Power Park Units 1 and 2 to allow the operation of one scrubber tower during low load operations. Northside Generating Station (NGS) and St. Johns River Power Park (SJRPP) are JEA solid fuel plants located near each other in Duval County and are covered by the same air permits.
The NGS Boilers Nos. 1 and 2 are two coal, coal coated with latex, petroleum coke, and landfill gas-fired circulating fluidized bed (CFB) boilers.
SJRPP Boilers Nos. 1 and 2 are fired with pulverized coal, a blend of petroleum coke and coal, natural gas, new No. 2 distillate fuel oil (startup and low-load operation), and “on-specification” used oil. SJRPP Boilers Nos. 1 and 2 each having a nominal nameplate rating of 679.6 MW.
SJRPP Boilers Nos. 1 and 2 are dry bottom wall-fired boilers and use an electrostatic precipitator (ESP) to control particulate matter, a wet limestone flue gas desulfurization (FGD) unit to control SO2, low NOx burners and over-fire air to control NOx, and good combustion to control carbon monoxide. Each FGD consists of three scrubber towers. During low load operation, one scrubber tower may now, under this new permit, be utilized to meet SO2 limits.
