hydrogen/oxygen mix - help?

Good afternoon

Does someone out there have experience of hydrogen/oxygen mix for their minor bench burner?

Do you have a flow rate? Pressure?

Any help would be greatly appreciated.

Warm regards

Jane

Hydrogen? Talk about living on the edge.... I thought the hydrogen fueled flame was close to invisible. ??

If used, Hydrogen would be a flow ratio of two to one of Oxygen. Since end product becomes H2O. I'm guessing the pressure would be similar to propane gas, about 5-15 PSI.

Most people I know use propane gas because it 1) can be supplied/provided at higher pressure than natural gas (without a pressure booster) and 2) has higher BTU content than Natural gas 3) is relatively cheap and easy to obtain (not sure what H2 bottles charge for refills)

Last I checked, my minor torch was designed for propane.

MINOR BURNER by Nortel The standard for soft glass beadmakers and small borosilicate work. The Minor Burner is a surface mix torch and is therefore as quiet as a whisper. It can be adjusted to a reduction, neutral or oxidation flame each of which affects soft glass colors differently. Use with propane or natural gas and oxygen.

pros are it burns way hotter and way cleaner than nat. gas or propane. Making the glass work faster takes time to get used to.The cons: It's *extremely* flammable! You may have problems (zoning, fire dept., safety inspectors, etc.). It's also expensive, it costs a little more than oxy but burns way faster like 2 or 3:1.What type of work are you doing? I wouldn't recommend it unless you are doing (a lot) of really big lathe work. Otherwise it won't pay for itself.Oh yeah be real careful working color w/ it. It will *all* end up clear otherwise!

Here's another site that discusses various fuels and their uses.

can produce flame hot enough for melting platinum...so I guess the better question is "whatcha making??" Warm regards? That can be blazing HOT! ;-) Jim

Are you considering purchasing a Watertorch unit or something similar? I was in contact with someone for a while who was supposed to set me up with a rental unit so I could test it out on my torch, but they disappeared so I have not yet had a chance to try it.

If you do try it out, please post about how it goes!

First you would need a burner designed for hydrogen. Burners are jetted for the fuel they are designed to burn. The instructions would come with it. Anything else is dangerous. The peculiar thing about hydrogen is that it gets hot as it expands as opposed to other gases that get cold on expansion. This can make leaks very dangerous.

Good luck,

Jack
