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 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
