- Note:
- Saving for Preheater = Rs. 35,284/- per Annum
- ROI Calculation:
- Belt Conveyors:
For 9000 TPD plant, there are 21 Major Belt Conveyors whose length is more
than 50 Meter, if we consider 12 hours of illumination in night and out of which
only 1 hour is utilized for normal inspection on daily basis, then 11 hours of idle
illumination is there. So if we go for occupancy sensor for the same then there
would be a huge saving on this account.
