Power Plant Saves Over US$20,000 Annually on Tank Cleaning Labor Problem: A Midwestern coal-fired power plant injected a lime reagent into a Spray Dryer Absorber (SDA) to control the emission of sulfur dioxide. The power plant recovered unspent lime from fly ash created during the combustion process. The fly ash was mixed with fresh …

The semi-dry technology has typically been employed on small to moderate size plants. Because of size limitations on the absorber tower, the maximum power served by a spray dryer is about 250–350 MW. Power plants with semi-dry FGD usually burns low-sulfur coal, in virtue of a limit of 95% on SO 2 removal efficiency. The semi-dry …

The rotary atomizers were used to spray water to maintain a temperature below this permitted temperature. The plant struggled with operating the SDA's to cool the gases, so that the temperatures could be kept below 300°F. The Atomizer also had issues with hopper wetting and this de-rated the boiler in multiple instances.
