Case Study: FLSmidth Kiln Exhaust Systems


FLSmidth is a longtime client of Quickdraft, with our first exhaust system placed for the company in 1997. This company supplies the mineral and cement industries worldwide with everything from engineering, to equipment, to support services. As a leader in mineral and mining, FLSmidth often needs custom exhaust solutions for its operations.


High temperature kilns are often used in mineral and mining. These conditions are not conducive to inline fans with blower wheels or bearings in the air stream. Maintenance issues arise when the exhaust particulate from the kiln builds up on an inline blower wheel and thereby throws it out of balance. Costly hours are spent cleaning and realigning these moving parts, and safety issues abound when working in these high heat conditions.


FLSmidth needed an exhaust solution for its kilns that had no moving parts and could be customized for its many operations throughout the world. Quickdraft placed Venturi exhausters—which have no moving parts—on the kilns, virtually eliminating maintenance and costly down times.

We also supply special flanges on the Venturi (eductor) to mate easily with the pipe that is typically used in this industry. Our blowers can be resized for 50 hz operation and/or at high elevations up to 18,000 feet. FLSmidth has several customers at elevations that range from 2,300 to 13,800 feet ASL.
