Building an easy heater from burning H2 + O2
« on: April 15, 2005, 03:00:07 PM »
Hi All,
Chris from:
www.oupower.com
has currently designed a nice new electrolyzer with cheap
laundry powder boxes , so he can generate lots of
oxyhydrogen.
Now my question is, for winter time it might be good
to build a heater unit to burn the H2 and O2 in a controlled
and safe fashion.

Any idea, how to build a safe heater uniter ?

Then it could be seen, if the electrical input into the electrolyzers
would be less than the heat generated.

Maybe there is also a gain in this.
Must be tested. So what would be the best cheap to build
and safe heater ?
The next winter is coming in a few months...
Many thanks.

Regards, Stefan.

Stefan,

I have seen the Brown's Gas welders, and I have seen Chris's little torch on the www.oupower.com website.  I have tried and tried to get a 2H2/O2 flame torch to burn and all I ever get is explosion.  I've used syringe needles also and no matter how tiny the hole, it never just sits there and burns.......it always just blows up.

I do not add electrolytes.  I don't use distilled water.  I use straight city tap water.  (It has chlorine, flouride, etc in it)  Is my mixture different than the others?  This confuses me.

Do different methods/types of current of electrolysis produce different "grades" of the gas?  (i.e. monotomic vs diatomic, etc)  I'd be real interested in an explanation if anyone knows.  Perhaps this is some of my problem with using the electrolyzed mixture as a combustion engine fuel.  My produced mixture simply will not burn like shown in Chris's photos.

Hi,
you might add some more air with an aquarium pump to the mix.
There was one guy on one forum, who did this and got a pretty slow
burning flame this way.
So just mix the oxyhydrogen with air in a "y" connetor with the air from an
aquarium pump.

Now the question is, what will be the best nozzle or valve to burn the
gas mix, so it can heat a cold room in winter ?
Xotec did show in their video a burner, that heated up a ceramic plate
or something like this. Does this make sense ?
Does this then heat the room air more ?

Or what would be the best device to heat cold air
wth  oxyhydrogen-air-mix-flame ?
What kind of "oven" could be build to do this efficiently ?

Regards, Stefan.

I don't know what the limits are, but the water torch we use is as follows:
1. Uses one line of a standard oxy/acteylene torch head.
2. Tip is a #0 size. (have not tried other sizes - yet)
3. Electrolyzer pressure is always maintained @8-10psi.
i.e. it turns on @8psi, shut off @10psi.
4. As soon as I open up a torch head valve the electrolyzer turns on
to maintain at least 8psi.
5. After the bubbler (or flashback container) no other gas injected,
e.g. oxygen, at this time.
6. Flashback does not seem to occur very often.

Hi all,
I just joined as well.  It must be a coincidence but I just posted
a link to a hydrogen fireplace/heater in a few other groups
that I frequent. There was quite a lot of discussions on wether it was a good
product or a waste of energy. If you are using the fossil grid to power the electroliser, you are not any greener, so this particular product seems to be geared to a higher end market of people who want to feel like they are doing the right thing. If you had an alternative energy source such as wind or PV to power the electroliser, it starts to make a LITTLE more sense. The efficiency numbers don't seem to add up, though. If you use wind/PV it would be better
and safer to just use the power for base boards or water heating than burning hydrogen inside. You wouldn't want to waste wind/PV on baseboards though. Heating DHW and radiant floor heating O.K.
 
There have been some concerns about the system but , they state that it
burns the hydrogen at production so there is no build up of gas. You have an option of venting the oxygen in to the room or an addition to the fire. Hydrogen burns almost invisible in day light, but in a darkened room it is pale blue. Adding oxygen gives it a yellowish hue, copper, green, etc. They don't say anything about an added oderant such as mercaphan that is added to nat gas so you can smell it. That would be a good idea. There have also been concerns about moisture buildup on an unvented unit. Hope this helps a little.
Here is the link to the hydrogen fireplace

tallex, no need to state "bla bla bla if you're power comes from fossil fuel powered grid" that crap fills up forums and gets in the way of research, for now YES thats where I'm getting my initial hydrogen, If you don't like it stfu, fix it! pls do not write anymore of you're over repeated banter. thank you.

DADINK,

No need to be rude. I posted this a couple of months ago. For now I electrolyse MY hydrogen from the grid as well.
This message was sent once. No repetition. Any repetition comes from others that seem to believe that the hydrogen economy is a scam and I was posting a reply to some of the sceptics. I am a serious researcher and aim to develop hydrogen systems that can be used
efficiently with clean energy sources. Have a little bit more class and you might gain some friends here. You are not the moderator, Stefan is
and it is not your place to tell others what, they can or cannot post,
best regards
tallex

It's not you per se, It's just that when I pour over the internet looking for anything related to what I'm doing to assist, I seem to find the net flooded with "you know it's coming from fossil fuels" ..... It just tests my patience, I was just mad it took me a long time to find something of relevance and I expunged my frustration verbally instead of tearing my hair out.
I apologize

O.K. Apology accepted. You should of seen the flack that I got when I posted the original hydrogen fireplace link. Jeez, you would think these people had better things to do.
On a research note Has anyone used ss plates with a lot of holes drilled in them for electrolisis. In my experiments, there seems to be quite an increase in gas output. I was just wondering if anyone else has observed this,
regards

I have in the past used ss plates with holes and it helps to increase surface area of the plates and allows the electroylete to flow and allow gas to leave the plates. Flowing electroylete also helps release of gas and helps prevent gas turning back to water.



Reguards,

indeed, but I still think it's best to keep the gasses seperate

on the h2o gas front...go back to the site that explains it and read it a little better...the gas IMPLODES not EXPLODES and its NOT straight h20 gas either.

What are we using as a storage medium? How are we compressing the resulting gasses for mass storage? I'd like to play around with this a bit, is there a site that I can check out that will assist me in finding info on how to get started?

I live in an area that is hydro-electric, and their turbines are water propelled so, no worries about the grid here.
