Economizer. 3. Superheat/Reheat Panels
Economizer. Ash Handling System - This System removes fly ash from the economizer hoppers, then transfers the ash pneumatically to the pyrites transfer tank. From the pyrites transfer tank the ash is transferred hydraulically to dewatering bins. (c) Fly Ash Handling System - This System removes the mixture of fly ash and dry SO2 scrubber product from the baghouse hoppers, duct hoppers and spray dryer recycle bin hopper through a pressurized pneumatic system to fly ash stoxxxx xilos located adjacent to the bottom ash dewatering bins. In the fly ash silo, entrained air is vented off through a baghouse filter system. The major equipment components of this System are air conveyor flowers, a fly ash silo, bag filters, hopper feeders, fluidizing blowers, exhaust fans, and other xxxxxxated piping and miscellaneous equipment and controls. (d) Burial Area and Retention Dams - Bottom ash and the mixture of fly ash and dry SO2 scrubber product are trucked to an ash burial area, having a potential storage capacity of 10,000 acre-feet. The ash burial area includes an embankment will be constructed downstream of the ash burial area to retain surface runoff.
