There are over 90 fans used throughout Plant assessment for a vanety of tasks within the cement making process. Many of the fans used on site are controlled and monitored from the Central Control Room (CCR). Whilst looking at the controls for some of these fans the CP-EE team observed that many of them have inlet guide vane (IGV) or damper controls that were closed to some extent and are not operating at best efficiencies. Mosr of all the fans in Plant assessment has the best potential for energy savings. The CP-EE option to optimize fan use is by Installing VSD to control fan with fluctuation load. The original in vestment for this project is Rp 1,250,000,000.00 or approximately US$136,000,00 (1US$ = Rp 9,200). Where the feasibility study shows that the electricity saving can achieve 5530.120 kWH per year, Annual Cash Inflow per Year Rp 2,942023,799.30, or approximately US$ 320,000 Payback Period 5 month, GHG Emission 4,608.4 MWH x 0.724 = 3,336.41 TCO. New installation will just be accomplished at the end of March for 6 (six) inverters in grate 2 and 3 while the other 6 (six) in grate 1 is planed to be accomplished at the beginning of December. VSD Panel will be placed in MCC location.
