GAS
DISTRIBUTION PACKAGE FOR ESP |
|
| |
 ESP
utilization is a direct function of uniform gas distribution.
Non-uniform distribution can overload certain sections
of the ESP, leaving the rest under - utilized. The overloaded
section dominates the working of the ESP more sparks,
lower operating voltage & poor performance.
As a solution for this, IFI offers virtual gas distribution
package for ESPs. Under this, a 3D model of each ESP
design is created in the computer. By employing computational
fluid dynamics techniques, the gas flow pattern is analyzed.
Corrective changes such as modified turning vanes or
gas distribution screens are introduced until a correct
flow distribution is seen on the computer screen. The
fabrication drawings are prepared based on this study,
so that corrections can be implemented in upcoming shutdown.

GAS
DISTRIBUTION PACKAGE FOR BAG HOUSE |
|
| |
 The
over-bearing role played by gas distribution in bag
house performance is undisputed. The inlet & outlet
ducts influence the flow pattern in a major way. However,
as the plant layout decides the ducting lengths and
bends in ducting, very little can be done to modify
them.
Hence, IFI employs CFD techniques for bag houses. Every
inlet is tested for uniform distribution of the gas.
Effects of corrective measures such as diffusers to
reduce high velocity flow are tried in a virtual environment.
The most effective ones are then chosen. When implemented,
these measures ensure uniform loading of all the bags.
The abrasion of the bags is reduced and long life is
ensured.
