Advanced coal-fired slagging combustor for the low-emission boiler system

The Department of Energy, Pittsburgh Energy Technology Center has recently initiated a major engineering development program called {open_quotes}Combustion 2000{close_quotes} which is geared toward advanced coal-fired electric utility plants. The Riley Stoker Corp. is leading one of three teams developing a Low-Emission coal-fired Boiler System (LEBS), which will be commercial by the end of this decade. The Riley team includes Textron Defense Systems, Reaction Engineering, International, Sargent & Lundy Engineers, Research Cottrell, and Tecogen. In LEBS advanced pollution control goals will lower SOx and NOx emissions to 1/3 current New Source Performance Standards (NSPS) and particulate emissions to 1/2 current NSPS. Riley`s LEBS has selected the 4500 psi 1100{degrees}F double reheat cycle, which will include a high efficiency, once through supercritical Benson boiler.
