One of the biggest problems with using Trioxine (Heat Tabs) is that the only purpose made stoves for them were used in the military and even then, they were rare. And I have one stashed away and will post it at a later date. One of the first lessons taught to my generation of Marines in Infantry School was how to construct a stove in the field. Note: Through Boot Camp all of our meals were taken in a mess hall. In Infantry School, all of our noon meals were in the field, C-Rations, except on weekends, unless we was in the field then also. Which happened a couple times. I'm not going to try to teach, via this medium, how to construct a C-Rat Stove. But I will give you an option, that you can make in your den, while watching Dancing With The Stars. And yes, an Esbit stove works nicely for Heat Tabs also. The picture below is of a stove I made from an empty tuna fish can and some steel strips cut from the side of a scrap file cabinet. Trick here is to make sure the stove is all steel. The size of the risers will easily accommodate a Boy Scout mess kit components. You can also use Esbit fuel, Fire Sticks, or chunks of Starter Log as your fuel in this stove. Note the holes near the bottom. Those are so the fire can breath. This stove has 4 holes, but you can put as many in as you desire. Without them, the fire will use all it's available oxygen and well, you know the rest. Corners of the risers have been rounded so they will not cut into whatever bag or pouch they are carried in. This type of stove can be made from any food can made from steel. The risers are 1.100 inches high and set down into the can 3/8 (.375) of an inch. The riser thickness is .045 thousandths. I would not use any thickness greater the 1/8th inch.
