Hello everyone,

Is there any design rule to define the internal diameter of HRSG Economizer headers?
In two reference Boilers books, I have found that the axial velocity inside the Economizer header should be less than 6 m/s?

I think there should be a minimum internal diameter to ensure correct distribution of water within the tubes.

Thanks for your help.

Best regards.
