Precise calcining with energy conservation and emissions control

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 CO2 emissions. Energy and emissions need to be adequately controlled to consistently produce high-quality lime for cooking liquors.

Well-proven lime kiln technology with integrated auxiliaries

ANDRITZ’s expertise in lime reburning has been thoroughly and successfully proven in more than 100 installations around the world. The fully automated ANDRITZ lime kiln package demonstrates low heat consumption, low emissions, and excellent availability. In addition to traditional fuels, the lime kiln can also burn 100% biofuels without the need for any fossil fuels with gasification or wood powder technologies.
