Pulp mill lime kilns go fossil free Valmet

Typical wood-base biomass fuels used for direct fired rotary kilns range from wood chips and pellets to saw dust. At pulp mills, methanol, turpentine and tall oil may also be available for burning in lime kilns. These work well as support fuel, but they cannot normally cover the lime kiln’s fuel requirements.

In partnership with Andritz Pulp and Paper we offer complete refractory lining systems of rotary lime kilns for the Pulp and Paper mills. Improving the life time of your refractory lining and minimizing shut-down times of your kiln is our most important target.

Lime Kilns in Chemical Kraft Recovery Convergence Pulp

A lime kiln uses heat, motion, and airflow to convert lime mud to lime, or in chemical terms, calcium carbonate to calcium oxide. This process is referred to as "calcining". The most common lime kiln designed found at kraft pulp mills is the rotary lime kiln.

Paper Mill Lime Kiln Cleaning CARDOX Blast Kiln

A papermill in the eastern United States was experiencing heavy buildup in their rotary lime kiln. Industrial Access solved the problem by implementing Cardox blasting as a solution. Cardox is the most efficient, reliable and cost-effective method of clearing material buildup and blockages.
