Expect results

Two Metso Fiberboard Optimizer modules was installed at Medite MDF, Clonmel, Ireland, to optimize and control the two EVO Defibrator systems.

Each of the modules controlled pre-steaming flow, retention time, pre-heater pressure and disc gap. Each of the systems targeted a certain mat height and minimum energy cost, based on defibrator electrical consumption, steam consumption and dryer energy consumption.

Results

• Specific energy consumption has been reduced by approximatley 8%
• Specific energy consumption is trending down towards a 10-12 % reduction.
• Mat density variation is in the range of +/- 2-4% which is a significant reduction

(Light green= MPO on. Dark green/orange= MPO off.)
