Abstract
There is provided a cement plant including a chlorine bypass apparatus capable of efficiently reducing the chlorine concentration in a cement kiln due to exhaust gas extraction by a small amount, by preventing calciner exhaust gas low in chlorine concentration from contamination and extracting a part of kiln exhaust gas high in chlorine concentration. In the invention, a baffle wallwhich protrudes, on a lower faceof an exhaust ductof a calciner connected to the pipe inclination partof an exhaust gas piperising from a kiln inlet partof a cement kiln, toward a pipe inclination partside at an inclination angle α within a range of 20 to 60° relative to the horizontal plane, and a spacing between a lower end edgeof the baffle wall and an opposite wall planeof the pipe inclination part is configured such that an average flow rate of the exhaust gas between the both falls within a range of 15 to 35 m/s.
