Indian acetylene generator.

I always thought 15psi was the max safe pressure.

That could be the pressure at which it reacts with Copper and instantly explodes

From what I understand, the reaction with copper forms some kind of crystal, which itself is explosively unstable. I think silver reacts the same. Don't quote me on it, its just what I have dragged from the dark corners of my memory and its a bit dusty in there. The 15psi thng, I thought was to never set the regulator anywhere above that

Copper Acetylide I think its called.......Im the same I cant really remember

My grandad used to have an acetylene miners lamp. A cotton canister filled with calculated carbides and water in the top. A lever opened a drip for the water and c2h2 came out various a nozzle with a reflector behind it.

You seem to be right. I was sure I'd read, not thaat long ago, that 8 was the safe working limit. Oh well

 

[Parm]

Thats right

Middle of nowhere places like Grimsby........

I seem to remember that the reason we have this new plant is cause the old one had a "bit of a fire"

check this guy out he makes vacuum tubes and uses gas oxegen torch and compresses his natral gass main and uses oxegen concentraters 8:30 he starts talking about this torches

 

[chester dylan]

just watched one of his new vids seems his "dress" sence has changed a bit

I have heard of lads fishing, well poaching, using calcium carbide. They would put it, so i am told in something like a tobacco tin with a hole punched in it, then chuck it in where they knew fish were in the lake, pond or river, it would sink to the bottom and fill with water, giving off acetylene gas and when it reached the right pressure it would explode, stunning the fish, which floated convieniently to the surface.

Really........ingenious
i know where there is alarge tin of carbide

Spoken for, or possibly up for sale?

 

[TechnicAl]

We used to use it to measure moisture.
Unless there has been a big clear out (and I doubt it) it will still be where it was, but its not mine

 

[MattF]

Does it work on the theory that the amount of gas produced is an exact indicator of moisture level?

If you do ever get your hands on that, or if they decide to get shut, (assuming it's still there of course), any chance of a heads up for possibly getting some?

 

[TechnicAl]

The test involves a pressure indicating flask. You put the sample and the powder in the flask and the reaction creates gas pressure.

Fish for supper then ?
