For this process energy audit should be done properly 1. Optimizations of the
output 2. Reduction in specific energy consumption 3. Trouble shooting in electrical,
mechanical and process systems 4. Dust abatement 5. Quality assurance.
Explanation of Cost Analysis using ROI and CBR for False air reduction
The return on investment in conventional technology (non-renewable energy)
was (−103.59%) and cleaner technology (False Air Reduction) was (−109.97%) for
Rs. 1 investment. On comparing the two technologies were in loss. In terms of cost
benefit ratio conventional technology (non-renewable energy) (0.00 713) and cleaner
technology (False Air Reduction) (0.1184) and cleaner technology showed a higher
benefit. Along with loss in ROI and higher benefit in cost-benefit ratio of cleaner
technology, added benefits are energy saved as 1600 kWh per year and profit earned
as Rs. 0.076 lakhs per year (Table 1).
Operational modification done in areas: Ball mills kiln burner, Clinker cooler,
Kiln shell.
2.10 Compressor Power Reduction
Working process of compressor power reduction
Compressed air systems has various modification depends on the capacity like
Incoming air filters, inter-stage coolers, after coolers, air dryers, and moisture drain
traps, receivers, piping network, filters, regulators and lubricators Air compressors
can save significant amount of energy. Air compressors are used in a variety of large
scale industries to supply energy requirements, to operate air tools, equipment, and
instrumentation needs. Only 10–30% of energy reaches at the process end-use, and
balance 70–90% of energy is being converted to useless heat energy is lost in form
of sound energy, mismanagement and friction (Saidur et al. 2010).
Explanation of Cost Analysis using ROI and CBR for Compressor Power
Reduction
The return on investment in conventional technology (non-renewable energy) was
(−98%) and cleaner technology (Compressor Power Reduction) was (−95.8) for Rs.
1 investment. On comparing the two technologies showed loss in ROI. In terms of
cost-benefit ratio conventional technology (non-renewable energy) was (0.033) and
cleaner technology (Compressor power reduction) was (0.070) and cleaner technology showed a higher benefit. Additionally cleaner technology showed benefits in
energy saved as 6500 kWh per year and profit as Rs. 0.308 lakh per year (shown in
Table 1).
Advantage of Compressor power reduction
Energy saving technology, Operational and maintenance cost is less
