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.

22. BONDS IN BRICK WORK
Stretcher Bond
Header Bond
English Bond
Flemish Bond
Garden Wall Bond
Zigzag Bond
23. STRETCHER BOND
Bricks are laid as stretchers on the faces of walls.
This pattern is used in only for those walls which
have thickness of half-brick.
It is used as partition walls, division walls etc.
The bond is not possible if the thickness of the wall is
more.
25. HEADER BOND
Bricks are laid as headers on the faces of walls.
The pattern is used only when the thickness of the
wall is equal to one brick.
This bond does not have strength to transmit
pressure in the direction of the length of wall.
It is used in construction of footing.
27. ENGLISH BOND
In this type of bond alternate course of headers and
stretchers are laid.
This bond is considered to be the strongest.
In this bond, the vertical joints of the of the header
course come over each other; similarly, the vertical
joints of the stretcher course also come over each other.
Every alternate header comes centrally over the joint
between two stretchers in course below.
There is no continuous vertical joint.
It is necessary to place queen closer in the heading
course for breaking the joints vertically.
29. FLEMISH BOND
In this type of bond, each course is comprised of
alternate headers and stretchers.
This bond creates better appearance than English
Bond.
This bond is not as strong as English bond and is not
used generally.
Every alternate course starts with a headers at the
corner.
It is of two types:-
Double flemish bond
Single flemish bond
31. COMPARISON OF ENGLISH & FLEMISH
BOND
English bond is stronger than Flemish bond.
Flemish bond gives more pleasing appearance than
the English bond.
Broken bricks can be used in the form of bats in
Flemish bond. However more mortar is required.
Construction with Flemish bond requires greater skill
in comparison to English bond.
32. GARDEN WALL BOND
As the name suggests, this type of bond is used for
the construction of garden walls, boundary walls,
compound walls.
It is used where the thickness of the wall is one brick
thick & the height does not exceed two meters
This type of bond is not so strong as English bond,
but is more attractive.
34. ZIGZAG BOND
In this bond bricks are laid in zigzag fashion.
This type of bond is commonly used for making
ornamental panels in the brick flooring.
