THE CHALLENGE. In 2008, the Babcock Wilcox Company awarded AllenShermanHoff, the USA Licensee for Magaldi Power technologies, with a contract to supply a dry bottom ash handling system for its new advanced pulverized coal fired boiler at Dry Fork power plant, owned by Basin Electric Power Cooperative.
"DRYCON is the next generation of dry bottom ash systems," he said. "One of the unique design features of DRYCON is that it does not use belt technology; rather, it conveys the bottom ash ...
When pulverized coal is burned in a dry, bottom boiler, about 80 percent of the unburned material or ash is entrained in the flue gas and is captured and recovered as fly ash. The remaining 20 percent of the ash is dry bottom ash, a dark gray, granular, porous, predominantly sand size minus (½ in) material that is collected in a water ...
DryType Bottom Ash System. Bottom ash is collected in a hopper lined with refractory to withstand high temperatures; this also is treated as a transition chute acting as a temporary volume chamber. The ash accumulated at the bottom is evacuated by a special type of extractor connected through an isolating gate/door for maintenance or ...
