Alcohol stove explosion.

Post by Woods Walker » Fri May 25, 2018 11:34 pm

I am working on a review for an alcohol stove. It had a small explosion for some unknown reason. The temps were in the upper 40's. 10 years ago had the same issue only a much bigger bang with a Trangia Military burner. That flash pushed the cloth material out the bottom gap and sprayed my face with alcohol. It extinguished the fire instantly. This one was smaller with no damage to the stove. As it only happened once and for reasons unknown to me not going to include this in the stove review however will post this separately for discussion.

Traingia and Alocs.

Fuel was denatured alcohol. The stove basically new (Alocs was the one that flashed). Maybe 10 burns with 10 more after that. I have no answers.

Here is a video.

Can you give specifics on the brand of DE you were using? Different companies (Sunnyside, Crown, HEET, etc) are made of different amounts of ethyl alcohol, methyl alcohol, methyl ethyl ketone, and the like. This will have an effect on the flame characteristics when used as a fuel.

Disclaimer: I’m the R&D Manager/lead chemist for one of the companies that sells denatured alcohol so I kind of have a stake in this.

My two guesses on cause:
1. A drop of water inside the stove boiled and/or flashed to steam, raising the pressure and atomizing some fuel, causing the explosion.
2. Trapped airspace within the stove can create a potentially explosive air/fuel mixture, but usually doesn't ignite because the flame is quenched at the burner holes - one of these holes is too large, or another large enough gap in the stove design caused a flashback and ignited the air/fuel mixture in the dead space above the fuel reservoir.
