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.

6. The 8051 microcontroller has 32 I/O pins configured as four 8 bit
parallel ports and they are denoted as port-0, port-1, port-2 and
port-3.
All four ports are bidirectional. Used as input or output or for
both.
Each port can be used as either 8-bit parallel port or 8 numbers
of 1-bit ports.
All port pins are multiplexed except port-1.
Port-1 can be used only for I/O operation.
Each port is having a latch, an input buffer and output driver.
8. Port-0 can be used as a normal bidirectional
I/O port or it can be used for address/data
interfacing for accessing external memory.
When the control is '0', the port can be used
as a bidirectional I/O port.
When control is '1', the port is used for
address/data interfacing.
9. PORT 0 as an Input Port:
Let us assume that control is '0'.
When the port is used as an input port,
'1' is written to the latch.
In this situation both the output
MOSFETs are 'off'.
Hence the output pin have floats hence
whatever data written on pin is directly
read by read pin.
10. PORT 0 as an Output Port :
To write 1 on pin of Port 0, a '1' written to
the latch which turns 'off' the lower FET
while due to '0' control signal upper FET
also turns off.
Instead of logic '1' on pin, floating value will
be getting on the pin.
So to convert that floating value into logic
'1‘, it is need to connect the pull up resistor
parallel to upper FET .
11.
12. To write '0' on port 0 pin, when '0' is written to the
latch, the pin is pulled down by the lower FET. Hence
the output becomes zero.
When the control is '1', address/data bus controls the
output driver FETs.
If the address/data bus (internal) is '0', the upper FET
is 'off' and the lower FET is 'on'. The output becomes
'0'.
If the address/data bus is '1', the upper FET is 'on'
and the lower FET is 'off'. Hence the output is '1'.
Hence for normal address/data interfacing (for
14. Port-1 dedicated only for I/O interfacing.
When used as output port, not needed to
connect additional pull-up resistor like port
0. It have provided internally pull-up
resistor.
The pin is pulled up or down through
internal pull-up when we want to initialize
as an output port.
15. To use port-1 as input port, '1' has to be written
to the latch. In this input mode when '1' is
written to the pin by the external device then it
read fine.
But when '0' is written to the pin by the external
device then the external source must sink
current due to internal pull-up.
If the external device is not able to sink the
current the pin voltage may rise, leading to a
17. Port-2 we use for higher external address
byte or a normal input/output port.
The I/O operation is similar to Port-1.
Port-2 latch remains stable when Port-2 pin
are used for external memory access.
Here again due to internal pull-up there is
limited current driving capability.
19. It work as an IO port same like Port 2.
Only alternate function of port 3 makes its
architecture different than other ports.
The alternate functions of port 3m are,
