On another forum someone was asking about using natural gas and
I was thinking (scary )has anyone ever tried the following or do you think it will work. Pipe in the NG thru a 3/4 npt pipe to a reducer to 1/4 npt and add a tee to the burner using compressed air it would act as a venturi burner but you could adjust the psi on the air.:confused: :confused:
I really think it would work with propane and would probably be the same as a blower, but you could have more control over the psi of the air mixture.:confused:
 
Don't know about using compressed air. I guess it would depend on how big a flame you're trying to feed, but in most cases you want a high volume of air at a low pressure. Running the burner off of a compressor, you would probably have to have the pressure too high to get enough air flow, and it would blow itself out.
The problem with natural gas is getting it at any significant pressure. I think 1/2 psi is the standard maximum pressure they will pipe it into residential/commercial facilities. If you need more btu's they just run it in a bigger pipe. That pretty much screws you on using a venturi type burner where you use the pressure/velocity of the fuel gas to draw air in.
Natural gas does work just fine for forges though, thats what they used in the fabricating class I took at school.
 
I'm thinking air's air, IG, and if you can get the right flow it oughtta work fine for the propane at least. A savvy fluid dynamics engineer could run calculations to check the idea. I think the important point is that there are two factors, velocity and volume, that can be acheived through numerous combinations of pipe size and pressure. Try it, my friend, but do it carefully, starting low and working your way up. :)

BTW, the habenero crack was because you got a capzasin brain today and had a hot idea.... :D

Thanks for the non-help, Fatzo.:rolleyes: :jerkit: :D
 
Hey, it's YOUR idea. Go out there and try it. :p :jerkit:

I don't know what I could say that wouldn't be a guess, IG, and I'm not going to pass off an idea that might get your arse singed....

Boy!!! Do I wish you lived closer.:grumpy: :grumpy: I know where the exact spot I would like to stick the burner in once I got it fired up. HEHEHEHE!! I would probably have to make it over sized to fit correctly.:eek: :eek: Do they make pipe in 5" npt???? HEHEHEHE!!!
 
Ok, here's an idea: go outside and disconnect the line where your gas enters the house. Light it on fire. Get real, real close and blow on it. If the flame color turns more towards blue you'll have your first piece of experimental data....:p
 
Fatzo, I wish you could come over and assist me in this experiment because I believe all the hot air you have would at another value to this endeavor.:p :p HEHEHEHEHE!!!
 
Dude!!! The Jose' is not going into the burner, but I wonder what the alcohol content would be after going thru the kidneys????:confused: :eek: :eek: HEHEHEHE!!!!

IG
Natural gas lines usually run at very low pressure on the main line and even lower after the regulator. If you are going to introduce compressed air, you would have to do it after the natural gas was released into the burner head where you wouldn't back flow the gas line. Call your gas co. or look on the regulator beside your house (assuming you have natural gas other than that caused by habanero consumption) to see what the pressure is.

George,Don't hook the air line into the gas line in any way at all.It will back pressure the line and could cause a big explosion!!!
