Brs-3000T – Failure #2
I late completed a review of the BRS-3000T. In that review, I mentioned that i of my pot supports deformed later 10 or thence minutes of using the stove.
Links:
Since posting that review, a duet of other people convey come upwards frontward as well as mentioned that they've had similar experiences, including Miguel C. who kindly sent me the below photographs.
Miguel reports the following:
You volition banking firm notation inward the to a higher house photograph that the pot stands are fifty-fifty to a greater extent than deformed than mine were.
Some people convey criticized my role of a 1300 ml pot as well as three cups of H2O every bit "heavy." While mayhap person could misconstrue three cups of H2O every bit "heavy," an MSR Titan Kettle alongside only i loving cup of H2O cannot.
This is non a weight issue. This is a pattern as well as materials issue.
So, What the Heck is Happening?
Well, for one, the titanium hither is not melting. Titanium melts at close 3000 Fahrenheit (about 1700 Celsius). The open fire temperature inward air of a butane-propane mix (i.e. canister gas) is close 3500 Fahrenheit/1970 Celsius, but you'd convey to genuinely focus the flame, every bit inward a blow torch or similar, inward lodge to teach the metallic that hot, as well as air would tend to comport away the heat.
OK, thence it's non melting. So what is happening? Well, metals teach soft long earlier they melt. Think of a blacksmith shoeing a horse. He doesn't melt steel, pour it into a mold, as well as brand a custom shoe. No, he typically already has the shoe made. He only heats it as well as thence pounds on it until it's the correct shape. He heats it because the metallic gets softer, as well as thence it's easier to move alongside the metal.
The same affair is truthful alongside titanium. Long earlier it melts, Titanium volition snuff it to a greater extent than malleable. Metals are assigned a rating called a "service" rating. This a temperature to a higher house which the metallic becomes unreliable. The maximum service rating for titanium is 1100 Fahrenheit/600 Celsius, as well as that's for a genuinely high bird alloy. The alloy used inward a backpacking stove has a rating to a greater extent than probable around 750 Fahrenheit/400 Celsius. Our open fire temperature is 3500 Fahrenheit/1700 Celsius, to a greater extent than than four times the service rating of the metallic of our stove.
Titanium is a piteous conductor of heat. If the rut can't hold upwards conducted away, as well as the small, sparse pot supports of the BRS-3000T aren't going to comport a lot of heat, the temperature tin climb to a higher house the maximum service rating, as well as "creep deformation" tin occur. Creep deformation isn't a precipitous snap or anything similar that. It's a gradual softening of the metal. The metallic tardily droops.
In the illustration of Miguel's stove, he had it on for a fairly long fourth dimension (15 minutes) as well as it was a however night. With no air currents to whisk away the heat, the temperature of the metallic climbed to a higher house the maximum service rating, and... well, y'all tin only await at the photos, above.
The Good News
Miguel reports that he only bent the pot supports dorsum later the stove cooled as well as went on his way. He continues to role the stove. Now, how many times tin y'all create this earlier the supports break? I don't know, but I wouldn't force it. You desire to avoid getting the supports likewise hot.
I likewise only took my fingers as well as bent it back. The BRS-3000T isn't just a beefy stove. It's pretty piece of cake to curvature the thin little pot supports.
The Bad News
The bad intelligence hither is that Miguel's failure happened inward however air (or a breeze thence calorie-free every bit to hold upwards undetectable). My failure occurred when the air current focused the open fire on my pot support. I was thinking that all i had to create was protect the stove from wind. I however mean value it is important, vital actually, to protect the stove from wind, but i also has to worry close excessive rut create upwards inward the correct conditions. It's a combat of a wild carte du jour here, but inward full general shorter burn downward times should hold upwards OK.
Interesting stuff. More volition hold upwards revealed.

Not certain how it happened. I was only cooking rice as well as a loving cup of water. I was using the msr [Titan] kettle as well as 2 of the stands bent a lil.
The stove was on medium depression cooked for similar fifteen [minutes]. It got super red. There was no winds but it was cold. It happened at night.
