hydrogen-oxygen-steam flammability diagrams

I have a flammability diagram for hydrogen-air-steam mixtures.

Has anyone here seen such a diagram for straight hydrogen-oxygen-steam mixtures?

Well, what is it then, have you got one or not. If you do, why not post it? Show me yours and I'll show you mine?

If so I think I could create one from the other.

You seem very much on track. Make our day and give us a few more bits of info on this, Ky.

From NUREG/CR-3468. I have a hydrogen-oxygen-nitrogen from another reference as well. Frequently these diagrams just have hydrogen on the Y-axis and steam on the X, with air being the remainder. That format would be fine for hydrogen:oxygen:steam as well. I read somewhere that nitrogen is slightly less effective as a diluent than steam.

My "air" in enriched in oxygen, and as a worst case, I'd like to know where the "knee" at ~60% steam moves with all oxygen.

Now that he has given you what you asked for, please show us yours!
