Reprint of “Experiences in sulphur capture in a 30Â MWth Circulating Fluidized Bed boiler under oxy-combustion conditions”

In this work, SO2 emissions under different scenarios have been evaluated. Variables such as limestone composition, Ca/S molar ratio and bed temperature among others have been considered along different test runs in both air-combustion and oxy-combustion conditions to analyse its influence on SO2 abatement. Fly and bottom ash, together with flue gas analysis have been carried-out. Desulphurization performance tests results are presented.
