In process industries like sugar factories and other processing plants, there are lot and various types of fans, pumps and material process that are installed to accomplish process objectives. The existing operation trends and system arrangements of most process industries are not effective from energy saving perspectives, whereas there is a big room for energy use saving if the feasibility of such aspects are made visible. In this regard, many white papers are issued proving and indicating that process industries can gain energy saving by studying their current operation trend and implementing proper automatic systems. To this effect, a practical energy saving study is conducted in above mentioned sugar factory for its boiler “Draught Control System” equipped with ID (Induced Draft) fan running in fixed speed arrangement versus the Variable Frequency Drive (VFD) enabling to adjust the speed of ID fan in line with the actual demand.
