LAFARGEHOLCIM HOLLY HILL
In October 2013, the cement plant in Holly Hill, South Carolina completed a successful upgrade of their Kiln ID fan rotor. AirStream conducted in-depth system testing according to AMCA standards to determine the actual system resistance and flow distribution characteristics. The new rotor was modeled in the existing fan housing to deliver and increased flow at continuous temperatures of 500⁰C (932⁰F). The high temperature fan capabilities enabled the plant to significantly decrease cooling water, natural gas and electrical power consumption, reducing their carbon footprint. The project was completed reusing the existing fan housing, motor, and coupling. Verification testing was conducted after commissioning, confirming the fan performance and efficiency improvements.
