secondary super heater
secondary super heater
(OP)
thanks for help
the problem we have that the secondary super heater coils were
manufactured from different alloys 213T22,213T12,213T13(in the same coil loop)
and for convienace we are arranging to manufacture the
coils from SA213T22 only so if any one can advice if its
ok or not?

RE: secondary super heater
Nevertheless, since you are changing materials, you no longer qualify 'replacement-in-kind' so you still have to provide a calculation plus a lot more paper work for the inspector and meet code requirements for 'alteration'.
RE: secondary super heater
I would not recommend you proceed down the path of attempting to optimize the SSH into one alloy on your own. Why? Because you have not presented any information as to why you a replacing the existing SSH and because you don't have enough materials experience to attempt a re-design. Have a boiler OEM look at this for you.
