The main component is ethyl alcohol CAS:64-17-5, that's on the label ( Thank goodness for REACH). (Registration, Evaluation, Authorisation of CHemicals)

It also says denatured, that might be by Bitrex or might be by addition of Methanol making it methylated spirits. Don't drink it. The methanol, if used, could itself contain water. It's not required to name the denaturant used.

You will also see from the label that it is not sold as a food additive. More likely it is for camping stoves or lumenaires, or even for mosel boiler burners?

In France it should be cheaper than in the UK where tax might be applied. I do not know the detail of French tax laws.

Methanol would make total sense, I think it might even be considered a denaturing agent in its own right as it is definitely poisonous.

It is definitely flammable, it has a slightly lower heating value than ethanol, but also a bit lower boiling temperature.  This would lower the boiling point of the mixture so it would likely burn at a greater rate, which would tend to reduce any noticable difference for our purposes.

I wish we could find it at that price here as we use a Meths cooking stove when we are sailing, so we burn a fair bit of it.  Interesting that your Meths is coloured, ours is clear, but has a smelly poison added.  Not that my wife or I notice any smell in a well ventilated boat.

It will be interesting to see how it goes.

de "l'alcool ethylique dénaturé " is just ethyl alcohol with something added, usually methyl alcohol, to prevent its use as a drink, owing to its awful taste...
and you cannot remove these denaturing compound by distillation as being an azeotropic mix.
don't drink it, it just perfect for steam engine burner...

Thanks for your comments, guys. I think that to all intents and purposes this is the French equivalent of methylated spirits, with the methanol added to the ethanol to  dissuade persons of thirst from imbibing it.

Just to be clear: when I said


I would tend to trust the French on things cooking-related - they don't take any nonsense when it comes to food !


I meant that French people would be too discerning to use something like smelly old purple UK style meths in a fondue heater. And yes, MJM - it is and always has been purple here to remind us Brits that it's POISON...!

Have no fear, Gentlemen - I have no plans to either drink the alcool a bruler or to use it as a food additive!   :lolb:

Zephyrin  is well qualified on all counts to point the way here:

 

don't drink it, it just perfect for steam engine burner...

Cheers!

Catching up after a long absence...

Congrats on the boiler!

I'll be interested in seeing the restoration of those two gems you got.

Hi Carl.

Nice to hear from you.

Thanks re the boiler.

I have started on restoring the smaller Mamod already. The larger one appears to be in much better condition but on first try it ran somewhat sluggishly. Further investigation required...

I'll post in this thread when I have made a bit of progress.

Cheers,

gary

Still somewhat off-topic, but the picture below shows my third Mamod - an SE2a, with whistle and reversing gear.

So far it appears to be the best runner of the three as well as being in the best condition. I ran it last night (we had a friend staying - after dinner entertainment  :) ) and it went like a demon on the French alcool a bruler. No worries on that score...

Our friend is Russian and he brought a litre of Russian Standard vodka with him. It had a similar effect on me to that which the alcool a bruler had on the engine. Doesn't look that different either...

Still WAY off topic, and trashing enriching my own thread, this is one of the various reasons why there hasn't been much progress on my boiler recently:


Will post details of another couple of reasons before I get back to the serious business...   :)

This is what has kept me away from the boiler for the past while:



Two candlesticks as Christmas presents - the one on the left is for my daughter; the right hand one is for my 'other half'. Don't tell them though - it's a surprise...

Materials:

French walnut
Mahogany
Brass
Bronze
Stainless Steel
Aluminium
Copper
and
Reclaimed vintage French plumbing fittings

75 cl bottle of mead for scaling purposes only, you understand.

I got these done sooner than I expected, and am now back working on reconfiguring the firebox for the boiler - will update on that soon...

Very nice Gary, I didn't realise you did wood turning too  :)

Thanks Peter.

I'm very much the novice wood turner (as well as novice home engineer) but I really enjoy woodturning and it's a skill I'd like to develop in the future.
