The limestone’s temperature rises to about 900℃ heated by kiln flue gas of 1150℃, about 30% of them are decomposed, and they come into the lime rotary kiln by hydraulic rod, where the limestone decomposed into CaO and CO2. The decomposed limestone are put into the cooler, where its temperatures drops to 100℃ and released. The hot air (600°C) will come to kiln after heat exchange, …

Flue-gas desulfurization - Wikipedia

Most FGD systems employ two stages: one for fly ashremoval and the other for SO 2 removal. Attempts have been made to remove both the fly ash and SO 2 in one scrubbing vessel. However, these systems experienced severe maintenance problems and low removal efficiency. In wet scrubbing systems, the flue gas normally passes first through a fly ash removal device, either an electrostatic precipitator or a baghouse, and then into the SO 2-absorber. However, in dry injection or spray drying operations, the S…
