This is inspired by "what's" horizontal bubble section idea. 4" x 300mm. Will have a 3 plate bubbler above it. 2x 22mm risers extended along the base caped at the end with holes/slots/single long slot, undecided. 2x 3/4" downcomers. Upper plate will have downcomers distributing distillate to outer edges. More pics and plans to come. Sight glass each end.

Pretty unusual googe, took me a little while to get the jest of it. At first I thought well that's just a big vapor chamber, come to think of it might be something to think about too for slowing vapor speeds. I got it now. Keep us posted!

[googe]

Yep, I'm unusual cooker . Sorry about the confusion , will do a drawing soon explaining. Made some.progress today.

Googe, I love your ingenuity.

What is the last picture? I'm referring to the picture of the two tubes with elbows.

Also, have you given any thought to how you would insure that the pressure of the vapor that exits at the end of each horizontal bubble tube is the same as the pressure of the vapor that exits near the other end? For example, consider a soaker hose. Unless care is taken to manage water pressure, the amount of water that bleeds out of the hose near the faucet will be greater than the amount of water, if any, that bleeds out of the hose at the far end. When the faucet is barely turned on, all of the water bleeds out of the first few feet of hose, and no water bleeds out of the hose after the first few feet.

One idea that comes to my mind is to taper the bubble tube so that the vapor pressure increases along the length of the tube. Alternatively, you could increase the hole diameters along the length of the tube. Unfortunately, these schemes would only be optimized for one particular boiler pressure (heat input), and would no longer optimally work for other boiler pressures. Of course, maybe I'm being overly pessimistic, and if that is the case, then maybe varying boiler pressure would not have much effect on how well the bubble tube works in equally distributing the exiting vapor along the length of the tube. Or, on the other hand, maybe it is not important to equally distribute the exiting vapor. Maybe it is perfectly acceptable (or desireable) to have vapor exit only a few bubble holes when the boiler pressure is low and exit more bubble holes as the boiler pressure is turned up.

If there is anything I have learned as an engineer, it is: To test is to know.

The pic with the tubes and elbows are the risers. you have good points that I've been thinking about mate. I made the horizontal tubes the same length, same size holes, 10mm between holes. Just tried to keep everything uniform. as we all know, vapor finds the easiest path. I've done this as simple as I can for testing, things can be changed.

Googe, I am eagerly anticipating your experimental results. Wishing you the best. I love innovation !!

[googe]

Thanks mate, I'm looking forward to trying it out, will be a while.though, have holidays next week then will get into it.

where do the 2 vertical downcomer tubes lead to? the way I am viewing it, it looks like they are going back to the boiler, which is confusing me. I'm sure that I'm just not understanding it completely but it sure looks very interesting and innovative and once I make sense of it I'll probably be even more impressed!

[Sungy]

this is a great concept. I will be very interested in how this works out for you. Good luck and keep posting pics. Love that copper....

Your vapor up tubes look pretty restrictive. Be careful with excess boiler pressure created there. A simple blow out cork can save your life. You really only need to direct vapor below liquid level to create a boil in your thumper. I dont think your idea will work real well but who knows. Dont forget to ad a drain valve and possibly a fill port. My 2 cents.
Good luck. MR

I don't know if its soldered in yet but milling out the whole bottom might be a solution. It's not like it can be too open as long as it is submerged. Even then a blowout cork would still be a good idea.

Even then a blowout cork would still be a good idea.

The blowout cork would especially be useful during the experimental stages, when different hole diameters and layouts are tested. This is probably a good safety procedure for anybody trying new designs.

I once saw a thread where a boiler blowout was implemented with a J-pipe that was filled with water.

It might be useful to add a thread for pressure relief safety -- when experimenting with new designs -- to the introductory lounge.

It might also be a good idea for boiler vendors (e.g., Mile High, Custom Copper Still Components, etc.) to consider adding, as an option, pressure relief to their boilers, or as a separate, in-line column module, which connects between the boiler and the column with tri-clamps. These devices shouldn't be that expensive, or maybe provided at cost, for PR. Another thought is to sell pressure-relief-ready boilers, that provide a boiler opening for people to optionally add their own pressure-relief device.

Thanks, googe, your thinking outside the box has spawned other people to start thinking there too.

They go to the boiler hyko, they will have pee traps of some.sort. Thanks.sungy. Thanks Mr, when you say they look.restricted,do you mean the small holes on the vapors tube?. The riser inlets are 22mm each, so I was thinking they would be big enough cause the risers on my other plates are 1.5"?. I like the idea of a now off cork just to be safe!. Good idea about the fill port and drain too, will be easy to add. Thanks lampshade, I think it's.a.good idea too, I always take care when designing things to try and make.them.safe, but there could always be something you don't see, that's why it's great having second opinions like on here .
