Gorlev Sukkerfabrik, a sugar mill, located in Gorlev Sjaelland, Denmark, installed two Simatek 3C filters with Gortex fiber-glass bags for an average temperature of 160 degrees Celsius for coal-fired boilers.

Air volume for both filters are 57,000 m3/h (35,000 acfm). Each filter cleans 17,500 acfm of hot flue gases with coal ash particles. The sugar mill produces sugar from sugar beets, and the boiler creates steam as well as electric power.

Simatek Engineering provided the total design, including ducting, spark arrester, bypass, rotary valves, flyash screw conveying system, and controls, and the installation was completed within a few months during the summer of 1993. The four year warranty period expired in 1997, without any problems.

The sulfur content of the bituminous coal used as fuel for the oil fired boiler to create power and steam is max. 1%. The irregular coal qualities of varying Btu's and calorific values as well as large temperature differences have not caused any problems to the originally installed high-temperature Gortex fiber glass filter bags that now have been functioning to full satisfaction for almost five years.
