Corona dishcharge

I’m not quite sure what you mean. What exactly are you going to be using together? Are you starting with red fuming nitric?

No no when you make ozone via corona discharge, it makes ozone and potentially nitric acid in humid environments. Nitric acid it what can destroy the cell. But im not sure if corona discharge is making fuming nitric acid or the regular kind i dont want titianium self combusting lol

 

[Cory]

I want to wrap titanium wire around a ceramic tube to make a corona discharge cell.

 

[WVNed]

Do you use an air dryer or desiccant column?

Well, a small piece of titanium wire isn’t going to blow up your house. I’d just try it out, outside, and see what happens.

Keep it dry

Ah thank you for the clarification! I can’t speak to that since I have never done this. Is there any literature precedent you can fall back on?

I dont but i suppose i could just add one and not worry about nitric acid.The unit i bought used. The cell was barely pumping anything. It felt like it was plugged. So i did the cleaning thing by pushing ro water with a syringe through it. It cleaned it a bit and had flow. But the ozone output was so little it wasn't working. Thats why i suspect the coil broke in some place creating much less surface area for corona discharge to happen.

That said imagine a cell that didnt break down by nitric acid! You would have a long lifespan cell without needing to use dessicant. My goal here lol

What voltage and current does the psu operate at? Is it 60hz (50 in Canada?) or is it high frequency?

Btw-While i know little about this, I can bet that the manufacturers would be using anything that they could if it were possible to run this, nitric acid free, without a drying solution.

I may just do this lol unless someone has some reason not to.

The cell creates a place for high energy chemistry to take place between ions. The trick is to control what you feed it so you get ozone out instead of other stuff that is made instead like nitric acid.

So drying the air is intended to make the cell more efficient at what it is supposed to do which is make ozone, not just to prevent nitric acid formation. The next step is to feed it only oxygen. I haven't gone that far.

No literature that i can find plus all the scientific terms get confusing to all but a few edmucated lol

Id have to look when im home from work. Yes yes im busy working lol

Umm, blowing up your house?

Hmm well i suppose i could use dessicant. But isnt nitric acid formed by nitrogen in the air and not humidity?

 

[Cory]

Yes this is a very viable concern. Maybe there is a cheaper thing besides iridium lol

I say you perform a test, done on YouTube, where you drop a piece of titanium wire into some nitric acid that you bought off the sketchy guy...

Id say you are fine. I’d use a means of drying things no matter what as nitric acid is nasty stuff to be producing.

It makes NO which combines to NO2... if water is present it gets split as well, which allows the hydrogen to combine making HNO3

I am not a chemist but is is my understanding that this is a side reaction that occurs in the cell and is dependent on how much water is in the intake gas. It doesn't happen if water isn't present.

 

[WVNed]

I would expect these cells fail most often from carbon tracking where organics get burned in them and form conductive paths across the dielectric.

 

[Twitchy]

I'd get some bulk silica desiccant, and fill a container with it, and pull your intake air through that. When it's all used up, just bake the desiccant, and you can reuse it all again. Its pretty cheap, and your cells will last so much longer. (Store bought, or homemade)

I already do this. Above the trashcan on the left.

I am running the ozone into my skimmer and have the air in the collection cup recirculating back.
I made the hat for the skimmer and the tube on top has carbon in it. It is also fed by outside air.
I am not running carbon on the discharge water. This has been problem free for months.
I read all the problematic posts about using ozone and looked at the cost of a reactor and this is what I came up with.
I am in the process of upgrading the tubing to better stuff now that I know it works.
