Described is a plant for manufacturing cement clinker comprising a preheater ( 1 ) which comprises at least one last cyclone ( 1 d) and at least one next-to-last cyclone ( 1 c) which is connected in series via a gas duct ( 2 c) to and fed with a gas from the last cyclone ( 1 d), a calciner ( 3 ) which comprises at least one inlet opening ( 9 ) for introducing preheated raw meal from the last cyclone ( 1 d), and which is connected to a subsequent separating cyclone ( 4 ), a gas duct ( 2 d) which connects the separating cyclone ( 4 ) to the last cyclone ( 1 d), and which comprises at least one inlet opening ( 11 ) for introducing preheated raw meal from the next-to-last cyclone ( 1 c). The plant is peculiar in that the inlet opening ( 11 ) for introducing preheated raw meal from the next-to-last cyclone ( 1 c) into the gas duct ( 2 d) which connects the separating cyclone ( 4 ) to the last cyclone ( 1 d) in a vertical plane is located under at least one inlet opening ( 9 ) for introducing preheated raw meal from the last cyclone ( 1 d) into the calciner. Hence, without affecting the installation height of the preheater, it will be possible to locate the last cyclone ( 1 d) of the preheater ( 1 ) at an arbitrary height relative to the calciner ( 3 ), and preheated raw meal from the last cyclone ( 1 d) can therefore be introduced at any point into the calciner ( 3 ) without any use of lifting equipment. |
