Keywords: Limestone, Fluidized bed boilers, Flue gas desulfurization Laboratory research of the reactivity of limestone used for desulfurization of coal fluidized bed boilers have shown that reactivity of CaO after limestone calcination process in boiler is significantly influenced by reactions of CaO with SiO2, Al2O3 and Fe2O3 contained in ash.
· The OC and EC from coalfired coal has been reported (Ma et al., 2016). The conclusions from this study suggest that grate boiler emissions had higher levels of OC and EC, with emission rates about 16 and 10 times higher than those of the pulverised combustion boilers and circulating fluidised bed (CFB), respectively.

FOR COALFIRED BOILER FLUE GAS DESULFURIZATION (FGD) FOREWORD. When coal is oxidized (burned) as fuel, the elemental sulfur it contains is converted to SO 2. Some of this SO 2 is converted to SO 3 when oxygen leftover from the combustion process causes further oxidization in the boiler. A system equipped with a selective alytic reducer (SCR) to reduce NO X emissions will .
