Induced Draft Fan Solution
The cement industry has a need for high efficiency, increased productivity and throughput, reduced downtime due to equipment wear, and higher process quality requiring an innovative solution. Older technologies require clunky mechanical components and running the motor full throttle which wastes a tremendous amount of energy along with wearing out the equipment.
Incorporating a medium voltage Variable Frequency Drive (VFD) with customized software that maximizes the motor/fan performance achieves an increase in system efficiencies and process throughput. A side benefit includes the reduction in high starting currents and voltage dips that could cause nuisance trips of upstream protective devices. Additionally, the higher power factor contributes to additional energy savings which reduces operating cost.
