The demand of power is increasing exponentially results in installation of new stations whereas the sources of water are depreciating acutely. In future there may be a situation in which water sources may not cope up with this requirement.
Also the serious concerns of the regulatory authorities regarding usage of natural resources, definitely the norms will be further be tightened, which will curtail the freedom of usage of water in power plant.
In present scenario land acquisition is one of the toughest hurdles in plant installations which can be averted by locating stations in water scarce regions, by employing air cooled system which eliminates dependencies on water for CW.
Although dry cooling systems are costly technologies on techno-economic considerations, but foreseeing the future it is the need of hour to employ dry cooling system which offers possible solution for power plant installation eliminating the above mentioned challenges.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

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.

• Availability of Coal, Land & Water is becoming more
difficult for new power projects.
• Coal is an exhaustible natural resource. Hence, its
saving through efficiency enhancement is desirable.
R&M results in lower Specific Coal Consumption.
• R&M is one of the most cost effective measure for
getting additional generation.
• Additional generation from old units becomes
available in very short duration.
( Contd--)
25. • The benefits expected from Comprehensive R&M in a
typical 200/210 MW unit include : -
- Increased output by about 4 - 8%
- Improved Unit Heat Rate by 10 - 15%
- Extended Plant Life by about 15 - 20 years.
• There is a shift from ‘Generation Maximisation’ to
‘Generation Optimisation’ with efficiency enhancement.
Efficiency enhancement of about 8-10% is feasible in the
existing LMZ units.
• Increased emphasis on Environment for clean technology.
The environmental norms are getting more and more
stringent.
