Valmet Lime Kiln Optimizer

Valmet Lime Kiln Optimizer for a better quality of reburned lime and decreased emissions

Better quality of reburned lime and decreased emissions

Features

Fuzzy logic controls detect process changes and adjust mud filter speed, dry solids and excess oxygen level to maintain stable reburned lime quality. Residual carbonate analysis combined with fuzzy control algorithms is used in fuel flow control to optimize specific energy consumption of the process.

Benefits

  • Lower resid. CaCO3 level
  • Lower std of residual CaCO3
  • Lower std of excess O2
  • Lower specific energy consumption
  • Higher product rate
