Steam Reformer Design - Tube Count
Steam Reformer Design - Tube Count
(OP)
In the design of a primary steam reformer - can anyone explain how to obtain the tube count? I don't know what the heat transfer coefficient of the tubes is (because this is a function of tube count).

In my experience, the small "can" type reformers ( up fired, up flow) generally have a small number of large 5"+ tubes. The larger down flow reformers generally will go with tube between 2.5" and 5" depending on output and catalyst volume. The more exotic materials also may help the wall thickness / heat transfer rate / Creep life. A micro alloy tube may function better than a HP or an HP modified Tube.
I don't know that this helps but it may get you started.
