Energy Optimization In Cement Manufacturing

An air flow controlled fan is shown in 2. Fans are predestined for saving en-ergy due to a quadratic load charac-teristic. Normal operation of large fans consumes about 90 percent of nomi-nal air flow, which still represents a potential saving of 20 percent power. Nowadays VSD for large fans are usu-ally installed in all new plants. How-.
