    Producing consistently high-qualityburnt limefor slaking requires not only deep knowledge of the calcining process, but also effective energy conservation and emissions control. Thelime kilnis a huge consumer of energy in apulp mill, and a large potential generator of CO 2 emissions. Energy and emissions need to be adequately controlled to consistently produce high-qualitylimeforcooking liquors.
