You test what you want, for example the first shoot with a gun, with don t have to remove your self from the fire place, you put the gun and the pressure gauges inside and if it goes wrong you have a protection.
Is a universal safe box, you do what you want inside it.
In some pictures you can see that I put there one of my previews inventions, the H2R( http://www.spudfiles.com/forums/h2-quim ... ter,0.html ) in case of hydrogen explosion i have no problem.
I hope I have clarified all the doubts.

RJB are you in Porto now? I finished the remote ignition on my hybrid, want to test it out? Also I got something for you.

Thanks, it allows me to do more experiences with more safety and less fear.
If someone want one like this I sell.

Who gets to test this explosion-proof material first?

Polycarbonate

Polycarbonate is a thermoplastic engineering resin comprised of a derivative resulting from the reaction between carbonic acid and bisphenol A. It has characteristics of transparency, beauty and high mechanical strength and advantages as low weight, excellent thermal-acoustic insulation and greater resistance to fire, which has become widely known and used in various applications.

These characteristics have provided wide application in civil construction, such as translucent glazing and flat or curved roofs, replacing the glass, because the polycarbonate sheets can be cold bent to the work itself, provided they obey the manufacturer's specifications.

The polycarbonate is sold under various forms, and the flat sheets and Compact Alveolar Polycarbonate Roofing and those used in construction.

 

TYPICAL PROPERTIES

ASTM PROPERTY UNIT METHOD VALUE
Refractive Index D-542 to 1.586
D-density 792 g / cm ³ 1.20
Tensile Strength D-638 kgf / cm ² 665
Resistance to Flow D-638 kgf / cm ² 630
Compressive Strength D-695 kgf / cm ² 875
Modulus of Elasticity D-638 kgf / cm ² 23,820
Heat Deflection Temperature D 648-C 133
Coefficient of Thermal Expansion D-696 cm / cm ° C 6.8 x10-5
 

IMPACT RESISTANCE

The polycarbonate has outstanding impact resistance. Compact sheet used alone or in laminated glass composite systems incorporate a form of the most advanced safety glazing means. Specified appropriately can withstand impacts of projectiles fired from weapons of great power, from revolvers to .38 super automatic rifles NATO 7.62 high firepower.
The polycarbonate material is classified as security for structural glazing, it is 250 times stronger than glass and 30 times stronger than acrylic.
With this quality, the polycarbonate sheets provide high security against vandalism.
Two American Engineers got to test this explosion-proof material first.
I only buy the material and build the big box, I didn´t has you know, did the acrilic plates.

It looks nice, and it's great that you considered the wall materials for the strength, just a few questions:

What kind of fan is that? is it an open "squirrel cage" style AC fan as it appears to be or is it an explosion proof sealed fan? if not that will be a very likely reason for your explosion in the first place!

Did you design the lid to act as a "frangible roof"? If not you should reconsider! That is a very high priority in an container that can undergo rapid pressurization such as a gas combustion!

Also - merely screwing the polycarbonate onto the outsides such as you have done will create huge stress risers (effectively making them frangible panels!) and you won't reap many of the benefits of the material you are using! Instead you should run a strip of material such as aluminum flat stock/bar stock which is the same width as the framing underneath it to spread out the load. On that strip - drill holes the same spacing you currently have and put the screws through the backing material, then the polycarbonate then into the frame. Just a suggestion - you can make your device however you like!

Thank you,
I had to considered that...
The fan is an explosion proof sealed fan AC, now i turn it into an exhaust system, sealed with aluminium 'tape'...(As you see in the picture)
The roof was designed to suport the pressure that an explosion can create.
The point number 4 is a good sugestion, however I tested it and there is no overload onto the outsides,
But I will consider that in the next project, thank you....
These pictures show the exhaust system, What do you think?
