This presentation discusses the results of a techno-economic analysis (TEA) of a coal-fired utility scale power plant based on the indirect supercritical carbon dioxide (sCO2) Brayton cycle using an oxy-fired circulating fluidized bed (CFB).  A baseline plant configuration was examined as well as three variations to the sCO2 power cycle examining the impact of reheat (Rht), main compressor intercooling (IC), and a combination of reheat and main compressor intercooling (RhtIC).  Each plant configuration was assessed at two turbine inlet temperatures of 620 °C and 760 °C.
