Cyclonic dust collector pulls double duty
To solve pilot test problems, a southern Iowa power plant converted the system's existing cyclonic dust collector from a filter to a filter-receiver.
The US Department of Energy [DOE] recently funded several experimental pilot test programs throughout the US to find ways to increase the use of renewable fuels and reduce toxic air emissions. In the programs, coal-fired power plants used biomass [organic materials] to replace a percentage of the coal they burned. In October 1999, Chariton Valley Resource Conservation and Development [RC&D], Centerville, Iowa, spearheaded one of the programs -- called the Chariton Valley Biomass Project -- at the Ottumwa Generating Station [OGS], Chillicothe, Iowa. Chariton Valley RC&D is a USDA-sponsored, nonprofit organization that carries out local objectives related to economic development, community facilities, and natural re- source conservation in several south central Iowa counties. The OGS is co-owned by Alliant Energy, Madison, Wisc., and MidAmerican Energy, Des Moines, Iowa.
