The Anna E by Eddie-Sand The Anna E by Eddie-Sand
The last month or so I have been playing around with the designs for a full size 4-4-0. Using this fictional locomotive as a test bed for ideas and concepts. In this (dated) sketch I have a Lempor ejector and an Altoona Firebox. I have a few concept drawing of this locomotive in mechanical form.

I like the Altoona firebox simply because it's low slung roof provided a funnel in which to rapidly move hot gasses forward. They where notorious for burning VERY hot. I have been debating trying to couple the Altoona Firebox with some thermic syphons. Perhaps the low slung firebox will help induce a circulation of water to compensate for the lack of heating surfaces.

I also wonder if the Lempor is being restricted by the screens and shape of the diamond stack, even though the diffuser empties directly into the crown of the stack.

I'm sure I can get a few ideas on this from some more knowledgeable folk.

Interesting. :) I'd love to see this engine finished.

I kinda thought that would be your expression.

If I'm going to spend alot of my time on a thought experiment like this one, then I should give the darn locomotive a name worth the time and energy. Wait till you see the four pages of blueprints for this locomotive. ^^

If you do a straight stack give it a cap that way you will still have some ornamentation :)

I do not think I will be going with a Strait stack.

Maybe its just me, but I figure if the fire is burning hot enough, you wouldn't really need spark screens in the first place because whatever little tidbits of fuel from combustion in the firebox would probably have been thoroughly burnt and eliminated already.

You might be better off with a straight smokestack. Shotgun variety or otherwise. The sonic speed of the exhaust probably wouldn't help the screen either. :noes:
