Optimizing Plant Efficiency With Rotork Actuated Control Solutions 2026

NK Engineering has recently completed the supply and commissioning of seven Rotork IQ3 intelligent electric actuators for a heavy industrial plant in Northern Vietnam.

These actuators are deployed to control the outlet dampers of primary air fans – a critical position that directly governs the stability and safety of the entire boiler combustion system:

• • Precise airflow control: High-accuracy position/damper control ensures the primary air flow into the air preheater perfectly matches operational parameters across all load conditions.
  • Fuel gas supply optimization: Regulates hot air flow supplied to the coal drying system while driving the transport air stream that delivers pulverized coal from mills directly to the burners.
  • Enhanced equipment safety: Precisely regulates sealing air flow to shaft bearings, effectively preventing coal dust leakage and safeguarding mechanical components.
