Air Throttles for Canister Stoves?

[Rex Sanders]

IF canister stoves with roaring, flickering blue flames have too much pre-combustion air under most conditions, maybe we can add air throttles. Here are some ideas for those who like tinkering with stoves.

For example, the MSR Pocket Rocket 2 draws in pre-combustion air through three holes around the jet:
Ideas

– Wrap aluminum or titanium foil tightly around the base of the jet cylinder, just the height from the red base to the bottom of the holes. Slide the foil ring up and down to adjust the throttle. Pinch a tab out to keep fingers away from the hot stove.

– Add a metal ring with holes or slots matching the air holes. Rotate the ring to adjust the throttle. Including a finger tab should make construction easier.

Every stove model is different, and might require some creativity, like the MSR Pocket Rocket Deluxe:

Snow Peak Gigapower Stove 2.0 Auto:

BRS-3000T:

Fire Maple FMS-118 remote canister stove:

Kovea Spider remote canister stove:

MSR WindPro II remote canister stove:

Remember: You absolutely do not want yellow flames. Keep out of reach of children, and most adults. Be careful anyway!

Interesting idea

(You must be trying to get stove manufacturer’s heads to explode saying this – or their lawyers)

I’ve wondered how wind affects this.  If it’s windy is there more air going to the jet?  Or less?

Would any of this reduce the amount of fuel required?  Or increase?

I can’t say I have ever seen a stove which was getting an excess of air. Methinks it is a non-problem.

As for the effect of wind – it’s very simple: use a windshield. We KNOW this works well.
