Nasa Burner - Inside?

[PistolPatch]

[Was just about to post this but thought I better check if anything else had been written first. LOL Guest and very interesting! Makes a lot of sense to me. But, I've spent so long writing the following to avoid my GST, I'll post it anyway Could even be one valid point at the end.]

Well done for digging that up NRB!

Glad to see those figures. I'd been wondering if I'd missed some obvious factor but the figures aren't too different at all with a volume adjustment. Obviously, there's not going to be a huge difference between the NASA and the 3 ring. (Whoops! See Guest's post above)

The missing time value on the NASA figures is time from from mash temp (say 66) to boiling which of course is much slower. But, I'm thinking that this probably isn't even important as when I brewed traditionally, the 3 ring would still keep up with the batch-sparge, i.e. a boil was only a few minutes away from the end of the sparge.

With the Brewing In The Bag stuff I've been doing, the whole sparge is eliminated so I gain over 30 minutes anyway. Hard to compare now...

Interesting stuff. Looks like I can still keep recommending the 3 ring though - cool!

I know this is getting off-topic but I think Tony will appreciate the info...

The thing that has really just struck me, is that when I first considered burners, I just thought about how quickly it would boil my liquor. I'm now thinking I should have thought more about control during the boil.

Cheers,
PP

P.S. From Guest's post, obviously a lot of what I've written is invalid. I use a 70lt flat-bottomed pot so please apply my comments above to this type of vessel only. If you have keg-shaped vessels, Guest's post will serve you far better!

I quite enjoy the sound of a cranked up nasa or two.Anyway if the noise bothers you put on some loud brew music.

And if the 10l of evaporarted wort isn't enough, you'll be sweating another 5 by boiling in a room in summer...
My leg gets sore from being to hot with the occasional stirring i give my boiler+NASA, you'd hit some serious room temp numbers i think!

I own a three ring, a four ring and a NASA. I have done comparisons with exactly the same pot (although it looks rather like a keg), in exactly the same location, with exactly the same windshield but with the three different burners underneath. In a test for how long to get 60 l to boil, I cant tell you how long for the three ring because I gave up after hours. The NASA was about half the time of the four ring (in exactly the same situation, same pot, different burners).

So I gave the four ring to AusDB, who finds that with his flat pot, it heats much faster than it did with my (rather keg looking) pot, which gives us the alternative experiment, same burner, different pots.

I suspect that my experiences are quite similar. I have a rather wide-bottomed aluminium kettle, and my four ring cranked on full likes to lick up the sides of the pot somewhat. I can only imagine how much heat would be lost with a more keg-shaped vessel.

And in answer to the original question, hell no!

Probably not the total answer you're looking for however I use my NASA inside my garage which I'd deem indoors in a cold, drafty sort of way.

:excl: I make sure the garage door is well open when boiling though. Gets a bit fumey otherwise.

Apologies if this is a dumb question but I'm going to ask anyway.

Why isn't the boil done with the lid on the boiler? I do a lot of cooking and when reducing a sauce it's always necessary to have the lid off, but when minimising evaporation in cooking having the lid on stops a major proportion.

Again, sorry if it's a dumb question

well from my experience, as soon as I put the lid on it boils over. every time. Also some evaporation is desirable as it means you can use more water to sparge with and thus increase efficiency.

Likewise - Door & window open for good ventilation. No problems with fumes or condensation.

An open boil lets the DMS boil off - otherwise your beer tastes like cabbages (so they say)

What's DMS?

Mmmmm, cabbage beer.....

Di-Methyl Sulphide. Try a search on this site - it's been covered several times

Well my time to chime in!
With my el cheapo 80L chinese stock pot I have no trouble boiling 50plus litres of wort with GLs old 4 ring and actually have to turn various rings on or off to keep the evaporation rate down to an acceptable level.

The main difference is the chimb at the base of the keg, a flat bottom pot doesnt have one (pretty obvious) and therefore the 4 ring evenly heats the base of the flat bottom pot. Because a nasa or similar throws a longer jet of flame this gets up and heats the base of a keg better than a 3 or 4 ring does on a keg. But even with a nasa you have to watch out that it is not too close ot the bottom of the keg as young Mika Lika found out. Search for Nasa and Mika Lika and you will find out his experiences which a trip to GL's got back on the right track.

But getting back on track I would not like the products of complete or incomplete combustion from a nasa floating around inside my house unless I had a commercial extraction hood like in the fish and chip shops above it!!! (and with a suitable amount of makeup air)
