Primus 210 meets Trangia

I combined a Trangia and a Primus 210. I hope for more efficiency due to better wind protection. I made it just 'quick and dirty' to test it with some spare materials in my shed.
It was important for me, not to destroy one of them.

I did not compare the time to reach rolling water, but I think it is a liitle faster than without the Trangia.
First I was concerned about the air supply, but after boiling there has been no soot on the pot. So there seems to be enough air.

@Sternenlicht ,

That's a great idea, and it appears to work a treat!! Brilliant work, and I'm glad you gave this a try! Thanks for sharing the results here, too! Take care, and God Bless!

Every Good Wish,
Doc

 

Very clever construction.
Well done!

 

The Hillary Everest Expedition did something similar with Primus 210s. They didn't use Trangias, though.
There is some documentation in the Stove Gallery, I think.
Anyway, very clever mod.

Looks like something an enterprising tech sergeant would rig for a still.

 

Nice work!

It is interesting to me that after testing the Everest expedition chose a silent burner for those rough conditions. I was under the impression that here at CCS people consider the roarer burner more suitable for camping and that the silents are for domestic use. There must be more to the story. I saw where the silent burned well to a hypothetical 40k feet of altitude but the roarer was only good to 15k.

 

Nice work @Sternenlicht .

Have you tried it outdoor in a strong wind?​

 

Maybe there are drawbacks to a roarer stove in high avalanche country?

 

Apparently the silent worked better at high altitude - protected from wind of course.

 

Thanks for the links, I knew these setups before and they inspired me to make this.

I did not test it yet in strong winds.

A disadvantge of my setup is, that it makes the stove louder. The upper windshield acts like a resonating cavity. I have the same with my Nova in the Trangia.

Regarding silent burners, this is from the Royal Geographical Society's "Hints to Travellers", Eleventh edition, Vol two, 1938:

 

@Lemming

Quite interesting document! But why they were not satisfied with the roarers?

Ciao, Bastian

 

I read elsewhere that the roarers did not burn well above 15k ft.

 

Since the roarer and silent burner are essentially the same in the way they mix the air and fuel prior to the gas mixture reaching the burner top/caps, I would be interested in why the silent burner responded to the special nipple and not the roarer.

 

Similarly, I wonder why no commercial company has essentially put height adjustable legs on a 27 upper windshield (no heat deflector plate like above so that air updraft cools canister as designed) for use with any modern resealable canister-top lpg stove: or would it still make the corporate lawyers nervous?

 

@ROBBO55
I tested the stove at quite windy weather, but it didn't work that good. It was still sensitive to wind.
I changed the original wind guard against a closer one, and it works much better!

Cooking in stronger wind without aditional screen is possible.

Ciao, Bastian

 

Thanks @Sternenlicht , I thought there might be a problem. The new modification looks more wind proof.
It's been an interesting post to follow.
