Producing consistently high-quality burnt lime for slaking requires not only deep knowledge of the calcining process, but also effective energy conservation and emissions control. The lime kiln is a huge consumer of energy in a pulp mill, and a large potential generator of CO 2 emissions. Energy and emissions need to be adequately controlled to ...

d. The lime begins to sinter, if all of the calcium carbonate dissociates before a given particle leaves the calcining zone. This process occurs to a very limited extent during stage (c); but for most situations, it can be disregarded. e.
