Episode 7 - Flammability Range

Just because something is flammable it doesn't mean that it is flammable all of the time. This is an introduction to flammability ranges.

Thanks mate for making this video, really well explained an really interesting too, now i can go off and explain to people that as long as hydrogen is stored at 100% its not gonna explode

Great video. Certainly helped me understand this better. You have the toaster scene in the first Bourne Identity film. So when the gas reached the toaster the gas to air ratio had to be 5 to 15 per cent to burn/explode

Thanks for your videos.Helping me to understand all the reactions 👍👌

To take this lesson into some different examples- I would figure that with a propane torch or gas BBQ grill, the burners are designed for that optimal 4% mixture. The perfect blue flame indicates you've reached the optimal flammable point?

I've also noticed that concerts with pyrotechnics, they blow a very orange yellow fire ball or column straight up. Would that mean they are somehow creating a very lean 2% mixture?
Last question- Which fuel mixtures leaner or richer tend to go bang? and which mixtures produce more of a shock wave? I was learning about house gas explosions— some make a lot of noise, and some blow walls out and knock the house off it's foundation. Thanks Matt!

so the combustion ratio is like 4 parts oxygen to 1 part propane in a propane engine?

hi im currently using a Fire machine i bought off of ebay wwhere you put a cannister in the center and activate it with a DMX controller, id like to use a less potent fuel so that the fire isnt too high any suggestions?. i mainly want to use it for demonstrations indoor and cant have the flame go to high

That optimal mixture blast was tasty. Was that shot with your RX?

[bigbythebigbadwolf]

How is Flammabilty range calculated like when do you know when you reached the maximum or minimum

[tarasweeney]

Could this also be classed as fire gas ignition? Or am I completely wrong here 🙈

Very informative experiment from you sir. May I request to share and use your video to teach my colleagues in maritime industry.

It's not a "need to" thing, it's a "want to" thing.
