A Felt Ring Burner : A Cheap and Efficient Ring of Fire

Professor Hammock looks at the problem of finding a small diameter alcohol burner of a given height, that can double as the stand for an Esbit tablet. He finds a solution in lining a commercially available tin with a strip of carbon felt. In that configuration the burner brings 2 cups of room temperature water to a boil using 1/2 ounce of fuel. The burner takes all of 30 seconds to make, and (in bulk) costs about $1 in materials.

Good work Professor! I like your analytical approach. BTW, there is no cure for the DIT alcohol stove bug. I've been suffering from it for years. Your table looks like the slate from a billiards table.

@whoopieslings Good eye! That's exactly what that table is. You should see the fancy iron support underneath. I don't know the history of the table, we "inherited" it when we bought the house.

Thanks professor!! Another good video. I appreciate the detail and explanation. Too frequently while watching some other video an important detail is missing. Anyway, I had been wondering about the carbon felt and where to get it. Thanks!!

[ProfessorHammock]

@btsseeker yes, I know what you mean about wanting details about where to get things seen. I try to put myself in the place of the viewer and ask "What would I like to see right now?"

thanks for watching

One of the most thorough and informative video I've seen in a while. Love everything about this video.  I especially love the graphs you provided. Extremely informative. Thank you!

[ProfessorHammock]

@morninghope1 Thanks very much. I noddled a while on how to present that data, and once I saw I could easily change the color of a time-series line in PowerPoint, the highlighting approach suggested itself. We left-brained types like data!

Great video. Personally I use a chewing tobacco tin. Skoals is the brand and a chunk of carbon felt. The top of the can is steel. It is very small light and gets 2 cups of water to boil in about 5 minutes or so. I also like your setup that you have here as well. Keep up the good work.

Great video, love your use of data and controls. The tins look great. Do you know of anyplace to buy them individually?

I am really glad you got the DIY bug, combined with your analytical approach = me being able to make well educated decisions. Appreciate the work!

@ProfessorHammock I built one of these using the smaller 1 oz. container (TND1, 1.5 inch diameter) with the carbon felt ring. It boiled 2 cups of water in 9 minutes using 2/3 oz of fuel with the pot resting 1 inch above the top of the stove. Flame-out occurred at 20 minutes.  The smaller TND1 stove reminds me of the bongo stove that Tinny at Minibull Designs has made.

I have tried your idea before I saw your video. Just made my video showing my stove.Go to my videos to watch. Thanks for your great videos. I also got a littlbug sr after your video showed the small one. Appreciate the info you share. Ted.

very frugal design you have there. What about this, get a tin that is taller and larger diameter that your stove, punch holes around the top edge and make approx 20 mm hole in the bottom, place up side down on your stove, the idea is to get the fuel container hotter, but then again that close fitting windscreen may already be achieving this effect. Love the graph too.
