Super Silly Smoke Question
 

I was setting up my Halloween decorations and decided to give the old fog machine a test run. As it warmed up and started to produce fog I wondered.... Would this water based "fog fluid" be a viable option for producing smoke if I pumped it through my smoke pump then into the hot exhaust of my turbine? I like an experiment as much as the next guy but I figured I would ask to see if anyone had tried it, or had a logical reason why it wouldn't work or wouldn't work well.

I googled the product to see what is in it an this is what I got:
Typically, fog is created by vaporizing proprietary water and glycol-based
or glycerin-based fluids or through the atomization of mineral oil.
This fluid (often referred to colloquially as fog juice) vaporizes or atomizes
inside the fog machine.

I ask because there are numerous recipes for home made fog (as I am sure there is for some fluid, but more importantly because I can get it dirt cheap by the case on November 1st.

Anyone have any thoughts on if this would be worth considering or even pumping some through my turbine smoke pump. I noticed my fog machine smoke has a grey tint to it.

I think it’s a great idea!

I use conosol 260 which is a concrete release fluid, which is pretty much mineral oil. I pay ~$12 a gallon. Let us know how it goes!

What's the worst thing that could happen? Maybe ignite? You would just have an afterburner then.

That's what I was thinking. It's water based so no real danger even of ignition. I was more concerned with gumming up the smoke pump.

If I remember correct from my old Halloween fogger, the "fog juice" was very watery, so it might pump faster than smoke oil and may "spray" differently out of the nozzle.

Let us know how your experiment goes!

I had a professional fog machine from my band that got to hot. It cooked the fog juice. It smelled awful and gummed up every single jet in the fog machine. Fortunately it was brand new so it got replaced (was glad since it was very expensive) so while it won't ignite it does burn and gums things up. Probably won't hurt your pump but not sure it will actually be fog and I think you may plug up the smoke nozzle.

i'm curious how hot the fluid would actually get since it is nowhere near a heat source until it is pumped out the nozzle. There wouldn't be any preheating. That is not to say jet exhaust isn't hot enough to flash boil it at the exit point, just wonder if that is too late. I need to find out at what temperature it overheats and starts to boil. I also wonder if a little extra mineral oil would raise the boiling temp to the right point? I need a science and chemistry type to analyze what's in smoke fluid and recommend a blend. This wouldn't be an issue if commercial smoke fluid wasn't so overpriced.

Fortunately shot cooling a pipe will not be an issue as my smoke system is in a Boomerang Elan without a stainless steel pipe. I would be shooting the fog fluid pretty much at the last 2 inches of the rear fuselage.

that's way cheaper than fog juice is!

It is now $17/gallon.

I have been using Lubsoil Lubspar 107, a full-scale smoke oil from Tulco Oils. Costs less than $60 for a 5gal container.

Lots of plentiful and long-lasting smoke.

I mix a quart of baby oil in a gallon of diesel. Not as puffy white but effective for everyday flying. This is running that mix. It does smell nice.

That looks great! Don't down play it!

Is it just me? Or did anybody else notice the hazard warnings?

In California, doesn't fresh air have the "This product contains chemicals known to the state of California to cause.............." warning??


That's assuming you can find any FRESH air in CA.

It’s like smelling diesel or gasoline fumes.

Tulco now has a 1 pallet minimum for the 5 gal pales. 36/pallet. Wont release price unless you have an account. Just stupid. Guess I won't be doing business with them. Price is classified. F this new world.

Tony,

I suspect that a fog machine doesn't get very hot and the "smoke" you're seeing is mostly water vapor. That's not to say that this stuff won't produce smoke (or steam) when exposed to 800C turbine exhaust.

As an experiment why don't you put some in a spray bottle and shoot it into your exhaust stream to see what happens. That way you won't be risking your pump or nozzle.

+800*C Humm none of mine go that high, and in flight full throttle they never even go to 600*C at idle some go to 250*c and number I have seen from telemetry post flight was around 450*c generally in flight. For this purpose I’m looking at a K210G2 (700*c is the max, and pretty much for start)
