    Lime Shaft Kilns - ScienceDirect

    01-08-2017· Reducing the heat input would certainly lower the burning temperatures and this would increase the reactivity of the product, but at the same time the heat distribution over the cross section of the kiln shaft becomes more challenging. As a result the product in the centre of the kiln shaft would not be completely calcined anymore.
