Calculating Energy Requirements for HRSG in Hydrogen Power Plants

AI Thread Summary
To calculate the energy requirements for a Heat Recovery Steam Generator (HRSG) in hydrogen power plants, it's essential to understand that HRSGs are designed to recover energy rather than consume a specific amount of power. The energy recovery depends on various parameters, including the efficiency of the system and the design of the cycle. Testing and simulations are crucial for accurate assessments, but initial research can provide useful insights. The discussion highlights the importance of foundational knowledge in power plant design for effective analysis. Understanding these concepts is vital for a comprehensive dissertation on hydrogen power plants.

Hi guys,

I’m a final-year student studying mechanical engineering. I’m doing my dissertation on hydrogen power plants.

I had a question….

How would I work out the energy needed to run a HRSG in my cycle.

I understand this depends on various parameters and needs testing and simulations but just needed a rough ball park.

Thanks, any help would be greatly appreciated!!

This question doesn't make a lot of sense as asked. The HRSG is recovering energy, it's not a device that needs a specific amount of power to run, you size it to recover as much energy as you economically can.

Did you take your university's Power Plant Design course? This question at this level is a little disconcerting...
 
Thread 'What type of toilet do I have?'

Thread 'What type of toilet do I have?'

I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...

Thread 'Thread No-Go plug gage allows 3 turns to enter. That's too many!'

After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
