In cement plant #2 (CP #2), Hg was in an enriching status because it was a new plant with operation of several months and most input Hg was retained inside the production system, hence with a much lower emission factor of 1.8 mg Hg·t −1 clinker and Hg concentration of 0.15–0.49 μg m −3 in the stack gas. Kiln tail stack was the main ...
In dry kilns, raw mix with low moisture content (e.g. 0.5%) is used, reducing the need for evaporation and reducing the length of the kiln. The raw mix is fed into a combined preheater and precalciner apparatus, which heats and partially (nearly completely) calcinates the raw mix before it reaches a rotary kiln , .
