CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

❑ In unattended cutting
❑ For high-expertise parts
❑ Where EDM finish is specified
❑ For hard materials
❑ For sharp inside corners
❑ For the most complex geometry
9. HOW EDM WORKS?
o Uses very powerful sparks (~3x106 V/m)
o Series of rapidly recurring
charges
o Electroerosion
o Remove excess by fluid
flow
10. SPARKS
❑ The phenomena “Breakdown” occurs
❑ A path for the current through dielectric
❑ Locally 10-15.000 ºC
❑ Ionize the fluid
❑ Metal melts or vaporizes
11. PULSING SPARKS
❑ Periodically striking ( >100.000 sparks/sec)
❑ More accurate maching
❑ Controlling the on-off for optimization
On time Off time
12. WIRE EDM
❑ Needs wire feed
❑ Can work overnight
❑ Impossible to have narrower gap than the wire
❑ Can be close to wire diameter
13. ❑ Voltage changes with distance
❑ Distance must be controlled
❑ Manufacturer programs do all the work
❑ Promising method with oscilloscope
14. TOOL EROSION (WEAR)
❑ Tool is also eroded
❑ It can be replaced (wire feed)
❑ Affects the shape of workpiece
❑ Can be proceed with negative-piece
❑ Reverse polarity electoplating
❑ Deposits the eroded graphite back
15. EDM IS A MACHINING METHOD
TYPICALLYUSED FOR HARD METALS WHICH
ARE ELECTRICALLYCONDUCTIVE.
IT MAKES POSSIBLE TO WORK WITH
METALS FOR WHICH TRADITIONAL
MACHINING TECHNIQUESARE INEFFECTIVE.
16. ❑ EDM can be used to make fixtures, collets and jet engine blade slots, mold
cooling ribs and reinforcing ribs. This fact makes wire and ram EDMs ideal for
making magnetic reader heads for missiles, artificial joints, turbine blades and
car engine prototypes (bgpeck)
Engine Turbine Blades
17. APPLICATIONS
❑ Prototype production
The EDM process is most widely used by the mould-making tool and die industries,
but is becoming a common method of making prototype and production
parts,especially in the aerospace, automobile and electronics industries in which
production quantities are relatively low.
❑ Metal disintegration machining
Several manufacturers produce EDM machines for the specific purpose of removing
broken tools (drill bits or taps) from work pieces. In this application, the process is
termed "metal disintegration machining".
18. COINAGE DIE MAKING
This type of EDM is usually performed submerged in an oil-based dielectric. The
finished object may be further refined by hard (glass) or soft (paint) enameling
and/or electroplated with pure gold or nickel. Softer materials such as silver may
be hand engraved as a refinement.

drained).Initial flat stamping will be"dapped" to give a curved surface.
19. Small hole drilling
On wire-cut EDM machines, small hole drilling EDM is used to make a through
hole in a workpiece in through which to thread the wire for the wire-cut EDM
operation. A separate EDM head specifically for small hole drilling is mounted
on a wire-cut machine and allows large hardened plates to have finished parts
eroded from them as needed and without pre-drilling.

20. EXAMPLES OF USE
❑ Slots, keyways, square & hex drives
❑ Gears, splines
❑ Small or deep holes, especially in hardened
❑ Removal of broken taps and drills
❑ Hard tapping
❑ Machining of carbide
❑ Application of textured surface finish
21. ADVANTAGES AND DISADVANTAGES
❑ EDM is a method of machining parts that cannot be done by
conventional machines.
❑ “Since the tool does not touch the workpiece, there are no cutting forces
generated; therefore, very fragile parts can be machined” .
❑ The shape and also the hardness of the materials being used make EDM
ideal.
22. SOME OF THE ADVANTAGES OF EDM
INCLUDE MACHINING OF:
❑ Complex shapes that would otherwise be difficult to produce with
conventional cutting tools
❑ Extremely hard material to very close tolerances
❑ Very small work pieces where conventional cutting tools may damage the
part from excess cutting tool pressure.
23. SOME OF THE ADVANTAGES OF EDM
INCLUDE MACHINING OF:
❑ Intricate & complex details are possible
❑ Internal corners down to R .001" [.025mm]
❑ Small features down to .004" [.10mm]
❑ Very high accuracy attainable
❑ Precise control of surface finish
❑ No cutting forces
❑ Virtually no geometric limitations
