2.13 To Stop the Bag Filter Fan by Connection of Venting
Line with ESP Inlet
Process
Process Modification is done using venting line in Electrostatics precipitator (EP)
inlet to conserve energy by adding automated sensor and variable frequency drive
(VFD).
Cost analysis for to stop the bag filter fan by connection of venting line with
ESP inlet
The return on investment in conventional technology (non-renewable energy)
was (−91.09%) and cleaner technology (To stop the bag filter fan by connection
of venting line with ESP inlet) was (−64.71%) for Rs. 1 investment, both losses.
In terms of cost-benefit ratio conventional technology (non-renewable energy) was
(0.1177) and cleaner technology (To stop the bag filter fan by connection of venting
line with ESP inlet) was (0.3555) and cleaner technology showed higher benefits.
Also cleaner technology had extra benefits in the form of energy saved as 55,200
kWh per year and profit as Rs. 2.622 lakhs per year (Table 1).
Advantage: Automated and sensors are available, Energy saving technology
connected to variable frequency drive
2.14 Belt Conveyor and Pipe Conveyors
Process
Due to transport of materials like lime stone and calcium carbonate inside the
industry conveyor systems were used. And this conveyor are classified into two, Belt
and Pipe conveyor
Belt conveyor: Belt conveyor is an old method of transport using to rotatory poles
was used.
Pipe conveyor: Pipe is used in a vacuum method using (air sucking) in this method
there is no spillage and dispersion of air.
Advantage: No spillage, dust emission, Lesser area required for plant and
machine, Reduced maintenance costs, Investment required for 6 Numbers of
Auxiliary bag filters eliminated.
Explanation of Cost Analysis using ROI and CBR using for Belt and Pipe
conveyor
The return on investment in conventional technology (non-renewable energy)
was (−98.65%) and cleaner technology (Belt conveyor) was (−100%) for Rs. 1
investment, both losses. In terms of cost-benefit ratio conventional technology (nonrenewable energy) was (0.0295) and cleaner technology (Belt conveyor) was (0.3168)
where cleaner technology showed a higher benefit. Added benefits like energy saved
55,500 kWh per year and profit obtained Rs. 2.63 lakhs per year were attributed to
cleaner technology (Table 1).
