2.11 Reduction of Specific Power and Fuel Consumption
in Pyro Section
Process: Clinker is produced by the pyro-processing section were in this industry it
has been modified to Optimize heat recovery by upgrading the clinker coolers for
making in rotary kilns, Preheater/ pre-clinker kilns for clinker making in vertical shaft
kilns and Low temperature heat recovery for power generation for clinker making in
rotary kilns High temperature heat recovery for power generation for clinker making
in rotary kilns is attached and used. (Kabir et al. 2010; Emad et al. 2013).
Explanation of Cost Analysis using ROI and CBR for Reduction of specific
power and fuel consumption in pyro section
The return on investment of Cleaner technology (Reduction of specific power and
fuel consumption in pyro section) is (−63%) for Rs. 1 investment, depicting loss. In
terms of cost benefit ratio cleaner technology (Reduction of specific power and fuel
consumption in pyro section) is (0.447). Though loss in ROI and cost-benefit ratio
for cleaner technology, benefits in the form of energy saved 80,000 kWh per year
and profit earned Rs. 3.8 lakh per year (Table 1) were offsetting the loss. Advantage:
Low operational cost, Energy conserving technology.
2.12 Vertical Roller Mill Fan Optimization
Process of Fan optimization: High power consumption and low productivity. For
stable long term operation, when the system is found occurring a large variations
to control the grinding dust is accumulated in fan and when the system under small
variation adjustment automatically done so the machine speed varies. Due to the
decrease in the machines fan has a maximum optimization reduction occurs due to
this process by temperature and pressure, energy is conserved (Danielle and Patrick
2010).
Explanation of Cost Analysis using ROI and CBR for Vertical roller mill Fan
optimization
The return on investment in conventional technology (non-renewable energy)
was (−95.6%) and cleaner technology (Vertical roller mill Fan optimization) was
(−69.7%) for Rs. 1 investment, the two technologies were in loss. In terms of cost
benefit ratio conventional technology (non-renewable energy) was (0.1097) and
cleaner technology (Vertical roller mill Fan optimization) was (0.310) leading to
cleaner technology showing a higher benefit. Despite loss in ROI and higher gain in
Cost benefit ratio cleaner technology added further benefits through energy saved as
38,500 kWh per year and profit accrued as Rs. 1.82 lakh per year (Table 1).
