Anyone hear use jet fuel in their furnace?

I watched this video and it shows that jet fuel gives far more thrust than diesel does. So does that mean if I use jet fuel in my furnace, will it get so hot that it will melt my crucible and furnace refractories? Jet fuel thrust stats at 6:57 diesel fuel stats at 9:52.

 

He most likely got those results because the fuel system was optimized for spraying jet fuel. I looked it up once and the energy content was pretty much the same with diesel being more viscous.

Diesel: 45.3 Megajoules per kilogram
Jet A1: 43.3 Megajoules per kilogram

 

I’ve used it for a couple melts. Essentially identical to diesel.

I get more heat from waste motor oil than I do from diesel, then less from kerosene (Jet A), and less yet from gasoline. But I have a drip burner and can shoot the air to it to get a clean burn from anything.

I'm sure the video was a viscosity based effect, same as Mark said.

 

I believe Jason uses "sumped" jet fuel when he runs bronze.

(At least he does not soak day old bread in it. "Gun Street Girl," Tom Waits)

 

Seriously? I thought you knew I've been burning it from the beginning? I even quit using used motor oil and run only Jet-A. I get all I can carry off for free so that's a big incentive for me.
Jet-A vs Diesel may be almost identical, but the smell of the Jet-A burning is oh so nice! It smells a little better than diesel in liquid. But not by much.

 

I wrote what I did from the standpoint of a memory that isn't completely reliable due to age. I was more or less certain jet fuel was what you preferred to use - as well as how you commonly got it - but did not wish to be named an (inadvertent) liar.

Then again, I use charcoal lighter as a parts cleaner. I suspect it's a similar material - and I'm saving the used stuff to one day go in a furnace fuel tank.

 

That was to ironsides. Sorry about that Dennis. You replied half a second before I did.

That engine reminds me of the old piper aerostar that people convert to jet. Always wanted to fly one of these! Talk about cool.

Originally a twin piston prop.

 

This is as close I get to that engine and yes that is Jet A1 being burnt:

 

Repurposing a deceased brake rotor, I see.

Now that's some recycling!

Jet fuel can melt some stuff, all right.

 

I was just preheating it for the pot and it formed a thrust diverter .

 

JetA has 119000 BTU/gal vs diesel’s 139000 BTU /gal. So, clearly the is more heat in a gallon of diesel. Actually seeing a noticeable performance difference in melt times in my furnace setup would take some careful comparison work. I can tune my furnace to just see a slight difference in exhaust flame appearance at .19 vs .18 L/min. That slight variation is about the difference in heat contents. I suspect if I could make ten melts with the same ambient air temp, wind speed, and barometric pressure with diesel vs JetA I could see a difference. But, in my world those environmental variables are all over the place making fine distinctions tough. Mostly, if I am occasionally lucky enough to be given some JetA, I dump it into the fuel tank and fire up the burner while playing “Top Gun” at full volume! ;-)

Blend "furnace fuel" out of "whatever you have," keeping an eye upon the ambient temperature and how finicky your setup is?

That's currently what I'm thinking to do. Want a few (yellow) 5 gallon diesel jugs to put it in - while making certain at least 2 gallons of diesel goes in each jug before anything else. Does that sound OK?

 

You know you have a serious foundry habit when you study the F14 afterburner for visual cues on how to tune your furnace mixture .

 

There's an excellent detailed interview with the Northrop Grumman VP about the design of the F14 made by a California senior's group of all things, well worth watching:

 

It was a maintenance PIG! Just like it's cousin the F15. Both required tons of man hours for a single hr in the air.

 

Could be worse, could have been an F-111.
