I'm imagining a portable boiler/turbine unit that burns wood and creates steam for a turbine, generating electricity.
I was planning on using freshwater from a river or lake. (A simple filter will remove particulate matter and minerals.)
But then I came across something called a Deaerator.
Basically, the deaerator removes oxygen and carbon dioxide from the water. Those substances often dissolve in the water and, in a boiler, can cause metal corrosion.
So I'd like to choose a material that doesn't require this, if possible. Titanium? Bronze? Carbon-carbon? Iron-Nickle like they use in jet engines?
Edit: For the curious, this question arose from studying old steam trains. Pretty sure they did not de-aerate the feedwater there and just let boiler lifetime suffer. I'm wondering if some modern "miracle" material, maybe carbon composites, can eliminate the need for de-aeration.
