section I or viii
(OP)
Hi,
I am very new to ASME codes. Can somebody provide guidance on the following:
A steam coil is placed in the flue gas chimney of a process furnace. A type of waste heat recovery i guess. The steam goes to a shared steam drum. The steam drum accepts steam from other heat exchangers etc..
There is a gate valve on the inlet of the steam drum.
Is the steam drum considered part of the boiler-proper? and thus section i, or sectrion viii.
If there was no valve between the steam coil and steam drum then would it make a difference?
Thanks.

In the petrochem industry, the drum would more than likely be designed and stamped per ASME VIII, Div.1. One similar instance that we were most recently involved provided for production of steam in an olefins furnace. The piping/tubing/header in the furnace was designed per ASME I. The steam drum was designed and stamped per ASME VIII, Div. 1. The appurtances to the steam drum were PP stamped as was required by the jurisdiction. Don't ask me for the logic!!
In the past, sulphur condensers produced steam from burning H2S rich gas, the exhaust gas of which was transmitted through tubes (fixed tube sheet heat exchanger)with the shell side containing steam. These "waste heat boilers" were all U stamped.
You must check with the jurisdiction with regard to your particular case.
