Residue from the chloride bypass de-dusting of cement ...

Nov 01, 2016 1. Introduction. In the production of Portland cement in a cement kiln a large amount of dust containing off-gas is generated. When the off-gas leaves the rotary kiln its temperature is about 1000–1200 C.The thermal energy of the kiln off-gas is used to preheat the raw meal by counter current heat exchange in a multistage cyclone preheater (European Commission, 2013, VDI, 2003).
