Abstract

Using modified IEA-CFBC(International Energy Association-Circulating fluidized bed combustion) model, a 2 MWe oxy-fuel CFBC boiler is simulated and analyzed as a promising solution to reduce greenhouse gas emission from coal power plants. This study evaluated and compared the oxy-combustion characteristics of various coals. Also, the effects of CO₂ concentration (71–79 vol%), bed temperature (850°C) and coal properties on combustion efficiencies, CO₂ concentration, acid gas emissions were analyzed. Because of their higher N₂ and S content, sub-bituminous and bituminous coals were found to have SO_x and NO_x concentrations higher than those of anthracite. These simulation results from Oxy-fuel CFBC simulation of various coals can be used as operating parameters for design and development of commercial Oxy-fuel CFBC boilers.
