I'm planning on constructing a small natural gas carbonation furnace (about 2 or 3 cu feet of working space) with servo controlled gas and air valves and a wide band O2 sensor to control the mix. I'm guessing that at one end of the range, I'd want to run it at or near a stoich mix for heat treating stuff like O1 and 17-4 PH but what sort of mix do I want for case hardening mild steel? Are there charts available showing the relationship between time, temperature, lambda and depth of carbon penetration? What happens if I run it 'too rich'?
I'm planning on having second burn chamber to hopefully burn off any CO and carbon before I release the exhaust into my building's flue system. Does this sound like a good idea?
I hope I'm not cramming too many questions into one post, but also what sort of air supply will I want? Will a small blower work well, is it overkill, or will I need to feed it some O2? I know this last question will have some thinking I'm going for a Darwin award but I just realized last night how much better it would be to design my furnace around N.G. instead of electricity and I haven't had much time to research things yet.
Thanks for any help you can provide. I'll be sure to let you guys know how it eventually turns out.
