Title:
設備におけるセメントクリンカの製造方法及びそのようなセメントクリンカ製造設備
Document Type and Number:
Japanese Patent JP2011529845
Kind Code:
A
Abstract:
The invention relates to a process for manufacturing cement clinker in a plant having a cyclone preheater, a precalcination reactor, a rotary furnace and a clinker cooler. According to the invention, the flue gases produced by the rotary furnace are separated from the gases from the preheater so as not to mix them, the precalcination reactor is fed with an oxygen-rich gas and a portion of the gases leaving the cyclone preheater is recycled into said precalcination reactor, or even into the preheater so as to obtain a flux suitable for suspending matter in the preheater. The non-recycled other portion of the gases, rich in carbon dioxide, is adapted for the purpose of limiting the amount of CO2 discharged, by means such as sequestration means.
