Hi, I am designing a the evaporator of a waste heat recovery for my final proyect degree and I've a few doubts:
I suposed it as a shell-tube heat exchanger, a "bare tube boiler" and I saw that a fire boiler has a steam drum in the top (water boiler too), what I want to know is if it's possible to have the water-steam separator inside the boiler, I mean, as a kettle design.
Is it common? Or should I design the bare tube boiler as a heat exchanger conected to a steam drum?
Thanks!
