It's bascially a copy of the Esbit stove, from the looks of it.

One briquette, ok, probably. But a bunch of them will probably burn through the aluminum. You might want to try using the Sterno fordable stove/stand, and flipping it over with a bit of sheet steel (or better, expanded mesh) added- people have done similar for wood stoves, but charcoal can make a hotter fire than just wood can. (Or at least do it easier). Or the Isreali pocket cooker.

For something like the Esbit, there options with ethanol fired stoves, or a buddy burner.
