Whats the difference between the burner in the 25 and the newer model burner?.

Hi, Lee,

The older burners did not have a cap. No big deal, but I prefer the newer design where if there's alcohol left over after a burn, I just let things cool down, put on the cap, and I'm on my way. No screwing around with trying to get the alcohol out or having to waste fuel just because I can't retrieve it. With a modern burner, if you're going for a day hike, just add fuel to the burner and stick it in your pocket or pack. No need to carry a separate fuel bottle.

The simmer ring on the older burners was permanently attached by a hinge. The ring just flipped up out of the way when not in use. The simmer ring only covered the jets but did not have a "door" like today's simmer ring -- the center of the stove was still wide open. With the old simmer ring, you could reduce the output of the stove, but you had far less control over the flame than you do with today's burners.

Here's a photo of my vintage 1960's Trangia, still going strong. You can see that the simmer ring is flipped up. I apologize for the low photo quality. I think this is a cell phone photo.

Yes.

Cool, nice pics too.

Thanks HJ

OK, then you have the version made by Primus.

HJ

You're welcome of course.

I didn't have time to expand on this earlier, but if you've got the Primus made control, you should be able to mate it to a Primus Omnifuel pump, if you ever decided that you wanted/needed to. Like this:


In other words, with that fuel hose/controller, you could run your Trangia mounted burner on liquid fuels like white gasoline or kerosene. Trangia + liquid fuel burner? Talk about the ultimate cold weather snow melting machine! Keep it in mind for your next South Pole expedition.

Now that is absolutely AWESOME - I would NEVER have dreamed of that!

How about the nozzles - should they be exchanged when changing fuel? Or will that nozzle work well with other fuels?

The jet (nozzle) would have to be changed for things to be efficient. Getting a set of jets wouldn't be that big of a deal.

From my blog:

In other words, you'd just buy jets intended for a Primus Omnifuel and use those with your burner. You'd need an Omnifuel pump, and you'd need a fuel bottle from one of the following brands: MSR, Primus, Sigg, Optimus, or Snow Peak. You'd want to check that the threads on the Omnifuel jets will screw into your burner, but I'm pretty sure they're going to be compatible. Even if they weren't compatible, there are ways to modify gas jets if needed.

The jets shouldn't be too expensive, but a pump, well, those aren't cheap. But if you ever did some serious winter travel, you have the option of going multifuel. Pretty cool.

That's my first reaction as well. Call me old fashioned, but I stick with optimization for a single fuel. I'm OK with changing nozzles, but running one fuel through a nozzle optimized for a different nozzle gives med bad vibes.
