Jhz563, I have all three of the books you showed in your post above. I have read each one, cover to cover, at least twice. However, reading those books does not change the fact that modern American Steam locomotives do not have an "ejector."
Yes, I guess you could assign that term to the overall process of exhausting steam up the stack and using that energy to draw a draft on the fire, but when working in the steam locomotive world, that term is simply not used. As Steve said above, if you use that term around steam locomotive people, you'll be branded as one of those egghead "engineering types" when it comes to steam locomotives.
My point is that you have to use the lexicon of the industry you are working in if you want to be understood in that industry. In stationary power plant steam service, perhaps the use of the word "ejector" is commonplace. It is not commonplace in the steam locomotive industry. That doesn't make it wrong, it's just different.
