摘要： Described is a plant for manufacturing cement, which plant comprises a cyclone preheater (1) for preheating cement raw materials, a calciner (3) for calcination of preheated cement raw materials, a kiln (5) for burning cement clinker, as well as means (12) for removing volatile components, such as chloride, alkali and sulphur, from the cement manufacturing plant. The plant is peculiar in that at least some of the means (12) for removing volatile components from the plant are located after the calciner (3) viewed in the direction of movement of the gases. It is hereby obtained, that significant amounts of volatile components, such as chloride, particularly KCI, may be removed from the plant since the removal is effected at the location of the plant where the highest concentration of these components occur, thereby avoiding coatings and clogging further upstream in the preheater. Also, the energy loss will be reduced since the gases after the calciner have a temperature which is lower than that occurring immediately after the kiln, and, therefore, there the volatile components need not to be cooled to the same extent in order to achieve condensation. Another advantage of the plant according to the invention is that the draught conditions and the mixing ratio of the gases which are drawn through the calciner and the preheater will be far less disrupted.
