Application

Fans are used in industry to generate a flow ofclean or dust-laden air as well as exhaust gases.The gas temperatures can be as high as 400oC,reaching 450oC for short periods.

The FLS High-Pressure Fans, Type XP work atpressures up to 19,200 Pa and with performancesup to 190 m3/s and are designed tooperate in the cement industry environment.

The impeller has bolted-on plane, radial bladeswhich are easy to replace when worn or whenmajor changes in performance are required. Thefan has an access door for inspection of the im-peller and to facilitate the replacement of blades.The fan hub and impeller are balanced staticallyand dynamically to ensure vibration- free opera-

tion.The heavy duty design eliminates an emergencydrive which would otherwise be necessary duringpower cuts.

FLS High-Pressure Fans, Type XP, are fitted withself-aligning spherical roller or ball bearings. Foroperating temperatures above 150oC

Design and operation

the shaft is fitted with a cooling disc to preventoverheating of the bearing. The bearings arebolted to the base frame which is grouted intothe concrete foundation. In smaller fans, how-ever, the casing and the base frame are inte-grated into one unit.

Motor power is transmitted via a V-belt pulley(up to 250 kW) or by flexible coupling and a gear.Highest operating economy is attained by us-ing a thyristor-controlled motor.

Maintenance requirements are small. Lubri-cating frequency depends on operational con-ditions. The bearing temperatures may rise to100oC. Monitoring equipment to guard againstexcessive vibration in bearings is available as

required. Thermal sensors are included in fansfrom size 160 and upwards.

Size 160 and above are restricted to seven stan-dard handings, but this restriction does not ap-ply to sizes 50-140.

Type designations are XPF or XPW followed bydigits indicating impeller diameter (cm).
