Whats the view on this? is it a non flash squirrel or nearer the real thing?

That sounds exactly how I'd expect a proper flash evaporator to work
-
Thanks Tony,i shall have another read then,is it a similar design to what you intend to make?
-
Similar but mine will be multi-pass as it won't be at such high pressure (his is at 6.0 bar and over).
For water really it'll be a glorified diffuser, but with Methanol it should properly flash.
-
Any progress on this Tony?
-
Got it all planned and done the calcs, will post them here when I'm back home. Will do the welding on that last though when I'm in the swing of it as it'll need to take 4 bar without leaking!
-
I should be starting to build my new evaporator in the next few week's , just getting some of the main bit's together. My plan is to buid something to de-meth in a single pass. When I have this working I'm then going to try adding extra heat to the heat exchange and extra vacuume to the vac vessel and see if it's possible to vac distill the bio. It all works in my head but I'm sure there will be headache's along the way.
My plan is a small amount in a constant flow.
I will update when things start getting put together

I posted this ...

on the VOD a while back in this thread ... http://www.vegetableoildiesel.co.uk/forum/viewthread.php?tid=19674
I thought it was a reasonable idea, but it had already been thought of and wouldn't work according to the experts.
Ho, Hum.

Hi Julian
I had a read of the thread but cant see any pictures (if there are any).
I think I have a really simple design but trying not to look to much into other designs until mine fails.
Probably the wrong way to go about it but if I go with gut feeling and it doesnt work at least I will know
Cheers
Paul

Can't see any either, thought it was because of my phone but perhaps not it seems!
-
I can see the pics, no problem. Just a link to my webspace ... these are the URLs

Not sure why others can't, can you see them in the VOD thread?
-
No think its a phone thing (iPhone 4s )
-
Both links redirect to http://mobilf.com/in.cgi?10 on my mobile (android). Can't see em on VOD either.
-
Ah it's Julian's site, it tries to do something clever for mobile browsers but it doesn't work. If you change the browser settings so user agent is ie6 then it works and the pictures appear.
-
Very interesting idea Julian. What stops the vacuum sucking bio up from the bio receiver via the bio exit?
-
The barometric leg. You won't get a high vacuum unless you have a very tall shed!
-
Luckily the Eve's of the unit are about 10M
-
from the pics this looks very intertesting idea, anyone made one yet?
-
I never got round to seeing picks but should be starting on the heat exchange for mine next week (weather permitting )
I think I'm going to do a drawing over the weekend and put it up for people's comments
