Germany will have the lowest dust emissions limits for cement plants in 2016. Russia operates on a plant-by-plant basis. In Turkey dust emissions are limited according to the type of abatement system used: ESP (pre-1993) = 120mg/Nm 3; Filters (pre-1993) = 75mg/Nm 3; Post 1993 = 50mg/Nm 3.

• Separate clinker cooler and bypass stacks as well as coal mill, cement mill and material dryer stacks measure dust emissions at least once per year. Continuous dust measurement at these stacks is recommended, in particular at the clinker cooler stack. • In case of AFR processing in the coal mill (co-grinding), the impact on VOC emissions ...
