Final solution for the flashback , solucion final para la retrollama

[djdsfhakdfhlksdhklf]

GREAT! Thanks for post/update. This really works! I see.

But oxigen reduces a bit the implosive fire efficiency. But clearly turning on the air in the moment the hho stops to come out, is the way to do. A simple 12 volt with back batery safety will do the job.

But the hho production must be good and continuous. A bubler will help safety.

Thanks!

HI ACe, yes I change the spring too !!! I agree most your ideas, and I am looking for a sinterized metal source , did you find one somewhere ?

Where are you located ?

regards

@daniel2008C I am from Serbia (ex Yugoslavia),and I ordered from one factory to make it for me,I just give him dimensions and shape(blue print). I put this in very small housing! Just two compresor connections and (or) adapter.Teflon seal(or soldering,but no opening).This is very hard arrestor! I can heat arrestor with torch and HHO still flow and stop flashbacks! No plastics,rubber,etc.I am to lazy to make videos,but I will!

to be continued...,

@daniel2008C ... And,I think you also (like me) use this one way valve for water refill?But,with SS reservoir and bubbler you dont need for any flash back protection...this is just in case of unplanned over pressure.

I not saw your answer on my "message folder",I think you must click on the right corner of my post to answer to me...please! Sorry for my bad English...

Bronze wool not so good solutions! I use harder materials,like grinding stone,SS mesh,and now sintered SS,the best,but you need somebody to make them for you. Air compressor is very good idea but not necessary.I use air compressor for make hotter (oxidizing) flame.But the best thing and more important is to make hard reservoir and bubbler!And maybe security valve(I think you use this,very similar like mine...I use one way valve for water,but I change spring inside).

Impressively smooth.. However, a bit complicated... Nobox is right on that one. A ball valve with a handle does the perfect trick to kill the flame without flashback. The knob on my traditional welding handle was too progressive and was letting the gas to slow down so therefore the flame was sucked back in and ignited the gas inside the hose. Now I use a quarter turn ball valve with handle and it's radical. Thanks for sharing.

Hola Daniel, como estas? Quisiera saber si el soplete al estar encendido y poniendolo en un contenedor lleno de agua se apaga sin flashback, te pregunto porque como es oxigeno más hidrogeno talvez la combustion siga. Gracias

Muchos saludos.

[daniel2008C]

SI lo haces rapidamente funciona , pero es solo una medida de precaucion , no lo uses como sistema principal de seguridad, porque depende de que lo hagas muy rapido , mas rapido de la velocidad de propagacion del HHO que es de ( creo) del orden de los 30 metros por segundo.

[daniel2008C]

3 LPM , para peceras grandes ,cuesta menos de US20 , diseñadas para trabajo continuo resultan bien en esto. La boquilla debe tener entre 0.25 mm para 1 LPM de HHO y 1 mm para 4 LPM de HHO , se pueden comprar hechas como puntas para acetileno ( 1mm) y oidos para cocina a gas las de 0.25mm ...buena suerte !! Gracias a tu anterior comentario, estoy usando un fuelle de goma intermedio ...para guardar aire X si hay apagon !!! ( con valvula de 1 PSI en el camino ) Gracias mil por tu idea

[stefyunico]

Gracias a Ti por todo. Mucha suerte!!

[stefyunico]

Hola Daniel, quisiera preguntarte dos cosas: cuantos litros por hora de aire sopla la bomba de aire para acuario que conectaste, y la otra pregunta, cual es el diametro del forado de la boquilla del soplete. Muchisimas gracias, un abrazo.

[daniel2008C]

Es cierto ! gracias por el comentario , y la idea ,

saludos para ChIle !

[stefyunico]

Muy bueno, pero no es aún 100% seguro, porque si hay un black out (apagón) de corriente mientras estamos soldando, el flash back se produce! Para eso habria que usar una bomba de aire con pilas para acuario , que se activa sola cuando inesperadamente se corta la luz durante la soldadura. Saludos desde Chile.

calamia13 just posted a great video showing the huge flame increase by using forced air.

[daniel2008C]

Hi Free..Thanks X the notice , Just checked it ,is a good useful work !

[NOBOX7]

hey friend did you no that using a small valve to cut the flame of works to avoid flash bak,,,also if you dip the flame in water it will exstingiush the flame without incident

[daniel2008C]

Hi, yes valve works but not always , .. if you are over 3 LPM valve alone is not secure enough .. also dip flame into water will work  most times , finally I think security does not come from a single precaution , but is the addition of several secure procedures ..best regards Daniel

[NOBOX7]

you are write about multi safty sytems

i use bronze wool ,a cut of at the torch

and i have two bubblers one washes the gas as it is very tall for a bubbler,perhaps that is why my flame stayes blue i have a very tall bubbler and i have bubble baffling that makes the bubbles smaller

do not use air stones as this causes drastic volume change in the bubbler,

also my gas washer has underwhen detonation lukely the small splash suppresure i use to keep water out of my hose blew of,i glued it bak

[daniel2008C]

Well.. with all these safety elements , you will not a have a flashback ! I guess most people reading this will realize how important is safety when working with HHO.. thanks for your contributions !

[daniel2008C]

Prezado Fernando , voce ten razon , O brigado per sus comentarios

DEAR Fernando, You ´re right, thanks for your comments !

[fernandodejulio]

Para se ter 100% devemos usar um borbulhador junto ao FBA e da tudo certo!

[freeenergeeeee]

Can you do a video showing the increased flame when the pump is adjusted up ? Thanks again.

[daniel2008C]

Dear Freee, please subscribe or send me your email by private message , I will send you two photos , with and without air, but don t expect a huge flame , air supply is just 0.5 LPM , so flame must increase ( 1L HHO +0.5L AIR = 1.5 lpm mixture ) but becomes more transparent , I will wait the night and use UV light to see the real size. If you want a real bigger flame , put gasoline or acetone into the bubbler, and with air pump flame becomes 300% longer

[freeenergeeeee]

I just subscribed but there's no need for you to send me any pictures because I believe your findings. I just thought that others might want to see the big flame increase caused by just pumping in other gas fumes combined with air.

Thanks, you're videos are great !!!

I love the resettable pressure relief device! Excellent design. They call it a vertical check valve. Very nice work. Great safety mechanism.

[freeenergeeeee]

Where did you find the resetttable valve and what material is it made of ?

Also, if the pump line is attached to the HHO gas line inside the bubbler using a "T" fitting then it must also be clearing out the HHO cell too ? Or are you just drawing off the HHO gas from the top dead space area of the bubbler ?

Very good idea !!!!

[daniel2008C]

Dear Freee the resettable is a modified ( quality ) water bronze valve , change the spring adjusting it to open at 3 PSI and will work fine.

The air pump is connected to the bubbler , under water level , as HHO but the opposite side of the bubbler , ( at top is the HHO output ). Aquarium pumps are adjustable , you can adjust it to mix air to the HHO ( if you need to add Oxygen for some tasks ) or less than 1PSI ( lower Pressure than Cell) if you don't want mixtures. THANKS !! for watching .

[freeenergeeeee]

OK, I got all mixed up by thinking that the pump was evacuating out the HHO gas. The pump is putting air into the bubbler water and then the air goes into the output torch line at a greater PSI then the cell's HHO gas PSI.

Also, does more air mixed into the HHO gas increase or decease the torch flame heat or flame size ?

Thanks for helping me understand.

[daniel2008C]

When you turn off cell power supply , HHO pressure decreases and THEN air is coming into the bubbler pushing out up to the last drop HHO , this is the reason flame simply reduces until disappears.

I adjusted pump less than 1 PSI , so air cannot come into the bubbler until HHO supply is off . BUT If you adjust air pump OVER cell pressure ( 1 PSI) flame is increased , becomes more transparent , but is not longer stoichiometric , since air has 20% oxygen, but works fine for most HHO tasks.
