I give electric supply at 10 A and 18 V. I use tap water in solution with baking soda. Apparently it produces quite a lot of HHO gas.
Yet, My aim is to get higher gas production.
Do you think my HHO generator is efficient? I've noticed that there is no increasing of temperature in my solution, but i've experienced problem with by transformator which convert AC current to DC. I found smokes at the wiring of transformator.
My cell gap is 5 mm and i use stainless stell plate 1 mm. ( 8 x 8 cm2 )
Best regards,
18 V on a +N- configuration is 9V per plate gap. Not very efficient.
You don't say how you are measuring your amps, but if your transformer is smoking, then I suspect that it is just rated at 10 amps and you are actually drawing much more than that. Make sure you have an amp meter in line with the generator. That will tell you what you are actually drawing.
I would reduce your plate gap voltage by adding in more neutrals. You only need 2 volts per gap; anything more is just wasted heat. So at 18 volts you would need +NNNNNNNN-
Also, if you want better production then use distilled water and either NaOH or KOH. NaOH is lye and can be bought at any place that sells cleaning supplies. KOH is Potassium Hydroxide and is usually sold for soap making. Baking soda does work, but it eventually breaks down into NaOH. Until it breaks down all of the baking soda you are producing CO2 along with your HHO, so it is just better to start with NaOH.
A 5mm plate gap is ok, but if you can get it closer then you wont draw as much current to operate your cell. On my dry cell I use the PVC shower pan liner which is .40 mil (about 1mm) as my gaskets. Some people here prefer to use about 2-2.5mm gap which allows for better gas flow at a small cost of amperage.
Any chance you could post a pic of your set-up? It would help to point you in the right direction.
