The report gives results of a survey of a wet limestone system for desulfurization of flue gas on the Cholla Power Generating Station of Arizona. At capacity, the boiler burns 54 tons of pulverized coal per hour. The system consists of two parallel scrubbing train modules, each accommodating 50 percent of the flue gas. Both modules include an adjustable flooded-disc scrubber for particulate control, followed by a tower. The module A tower is packed, utilizing a limestone slurry for removal. Module B removal is estimated at efficiency 25 percent. Installed cost for the system is reported to be about $6.5 million, or $57 per KW. Annualized costs are estimated to be 2.2 mills/KWHr, including a 23 percent charge on capital investment to account for interest, depreciation, taxes, and other fixed charges.
