Howdy,

Has anyone had a problem such as mine with Buflam #2?

It has a silent burner, and puts up a good size blue flame. After a couple of minutes, orange flame shows up--I have made certain that there is no underburning, or any change in the hissing sound. The transition from the blue to orange just happens so smoothly.

One thing I note is that the outer dome seems to heat up as the stove continues in operation: I can see it become dark red. Is this overheating, and not supposed to happen? When the outer dome has reached the dark red point, that is invariably when the flame turns orange.

Thanks for inputs in advance.

Same problem with the Companion silent I am currently using, the outer dome goes to bright red. The inner is somewhat rusted/burned as if metal has stripped off. The outer is not made of iron.

I've had this problem intermittently with an adjustable burner. Increasing the pressure to increase the gas flow rate and force the burner flames further from the cap seemed to help and seemed plausible, but the intermittency has me confused.

My Svea 5 was doing this recently. A decoke of the burner brought back the pure blue flame.

do you do an effective decoke - I have a few burners that would benefit I think. I tried citric acid bath and flush with some improvement maybe, but is there a better way?

I was lazy this time & just left it to soak overnight in a citric acid solution & then gave it a good rinse under the tap. I usually heat them till dull red & then douse in cold water & repeat & them blast through with water to rinse. I've just been given some cirtic acid so thought I'd give it a go.

In response to my own problem....topped up the fuel, very low level can do strange things to a stove, changed the inner dome for a non flaky one, light up, same problem.
Change the outer dome, now a 5 star burner. Only difference was the new dome was a heavier gauge metal.

It sounds like a winner. Say, where can one procure such a dome with thicker metal? What model stove did the dome come from? Is it made of brass, or steel? I suspected the glowing dome did nothing good to keep the hot gas from igniting before it came out of the dome.

Where does one get one of those?

The replacement dome was a spare, no idea what type. Unfortunately when Big Brother made it impossible for the average law abiding citizen to own guns here, I sold off my muzzleloader and powder scales, so I cannot do an accurate weight comparison of the two burner rings, but my little postage scales suggest the lighter on is about 20gm and the other about 29gm.

I had a hunch, and took out the domes of 111 Triple Fuel. The dimension was almost identical, except the height of the perforations.

I replaced the inner and outer caps with possible combinations, and...

No luck.

The Optimus caps perform a bit better, however, than Buflam's original. Although Optimus's cap was even thinner than Buflam's, it did not put out as much orange flame as Buflam's did.

I guess I will have to be satisfied with just looking at it.
