DIRECT USE OF CALCIUM OXIDE (CAO) IN THE DESULPHURIZATION OF FLUE GASES IN BOILERS WITH FLUIDIZED-BED TECHNOLOGY

摘要

Method for removing SO2 in the flue gases of a fluidized-bed boiler in which CaO rather than CaCO3 is used directly in the boiler. Said method permits optimization of energy and emissions to atmosphere as well as molar absorption of SO2 more than doubled compared with that observed when using CaCO3 in the boiler.
