James Maiwald Flame Licker / Flame Gulper doing some work
« on: May 10, 2019, 10:12:18 pm »
This is the first time I have seen a James Maiwald Flame Licker / Flame Gulper doing some work. I made an aluminum drive pulley and mounted it on the flywheel and the engine quite happily drove a Fleischmann wood saw steam accessory.

Nice run Jim ... I enjoyed seeing that realizing what an uncommon sight that is as well!

The reason you rarely see vacuum engines running accessories is due to their inherent lack of power based on the fact that they are operating on something substantially less than 14 psi. Seeing as they are often quite temperamental, and having little power, most any load is likely to be something of a problem for them. So you getting that one to pull the table saw was good!

I once got my Solar Engines #3 to run my Jensen #100 workshop, but it took a lot of fiddling and false starts to manage it, and I wouldn't bet any real money that I could do it again on any given try.

Thanks for the reply Daniel, the 14psi is interesting and I didn't know that.

I was happy to see it running this and will try a few more different things for it to run.

Jim, 14.7 psi is standard atmospheric pressure at sea level where you're at. The flame lickers work by creating a partial vacuum via the rapid cooling of thin hot air (hot air is much thinner, less dense, than cool or cold air), thus creating a partial vacuum, and do note that "partial", in that it is essentially impossible to create a true "total" vacuum here on earth, though space is extremely close and so qualifies in that regard ... but I digress. It is unlikely that a flame licker is producing even a half of a true vacuum, probably more like 1/3 or 1/4 would be doing good, so you are actually operating at less than 7 psi and more probably something like 3-4 psi. Thus very little actual power available with this type of atmospheric engine.

Hope that helps.

Impressive to see it run a load Jim.
Your nose is before your eyes, so trust it first!

Daniel, colour me impressed!
