Nice. I have something similar and used an inflation pin but I keep getting flashbacks. Any ideas? Does this happen from too little HHO flowing?

[aliasfoxkde]

No, this just happens due to burning. The same thing would happen during welding except that you have a backfire/flame arrestor. With this design you will also not have stable PSI which is possibly another issue. Not using an arrestor is dangerous. You can either use an oxygen/hydrogen arrestor (used for gas welding) or appropriately a Gas Torch Mount Flashback Arrestor (I would suggest the latter but either would be better than none and the welding one should run around $10).

Thanks for the reply. I did have a flashback arrestor similar to what is shown in the picture - a jar with the gas running through the water. But the flashbacks kept blowing the lid off the jar. I tried to let it run for a few minutes first to see if there was a problem with air mixture. Maybe it's something like what happens on a vehicle? If there are any leaks in the exhaust the car will back fire. Maybe I don't have a well sealed line?

HHO is the recipe for an explosion the perfect mix of fuel and oxygen, to get a sustainable flame you need to introduce an inert gas to reduce the burn rate of the HHO, you need to add an air compressor to the system and as air has a high percentage of inert nitrogen gas you can achieve a sustained flame. I know a guy who is tinkering at HHO production and he has achieved a sustained flame by this method.

I would say that the problem is that you have a complete recipe for combustion. A burn or explosion needs three things to happen. Oxygen, fuel and a source. The HHO is both fuel and oxygen in one, so having an air leak would not cause this problem. A venturi-type regulator like on some low-end grills would not do anything either. To be honest, the only flammable gases I have ever really worked with have been hydrocarbons, and usually the containers had a gas mixture too rich to backfire. I dunno how you can solve this problem, but the idea of PSI being a problem might help somewhat. Perhaps pumping it into a bike inner tube?

How do you wire the plates? i'm unsure on how to do that..

[ASCAS]

I punched small holes and tie the wire there. You may may solder it if you want.

If you want to increase the output and reduce the chlorine that off-gasses use potasium hydroxide or sodium hydroxide commonly sold as drain cleaners. don't forget that drain cleaners are toxic and caustic. so wear safety glasses and ear plugs, unless you feel like being a prime example of a deaf, dumb, and blind boy.

Whats the hydrogen oxygen ratio and how do you control it?

[Puff]

Its 2:1 and that's what its going to be. Water always splits into two hydrogens and one oxygen (H2O). As far as controlling the rates at which the gases are produced the surface area of the electrodes, temp of water, conductivity of water/salt solution, and amperage of the power supply all affect output.

you do want to add a check valve and a spark arrestor between the torch and the bubbler. Check Valves cost $0.68 at US Plastic and the spark arrestor you can make yourself. Nice job but be safe!
