This morning while cleaning out an area in one of our barns I stumbled across this rocket stove that my daughter build several years ago. Since I have seen a few threads here about how to build rocket stoves I thought I would take a few pics. Enjoy.

#1 The stove is made from two 5 gal. metal buckets. The interior piping is 4" galv. pipe from a big-box store. I think it was one 36" length of pipe and one 90° elbow. She put legs on it because we sometimes had it working on a flammable surface and the bottom would get warm. The three angle iron pieces on top is to keep the pan or pot above the flame. Both cans are full of vermiculite for insulation. When the stove is in full operation we try to maintain a 0" to 1" flame coming out of the pipe. We found that a flame any taller than 1" is wasteful and will scorch your food quickly.

#2 I stuck some twigs into the burning chute to show where the fuel goes when the stove is in operation. There is a divider baffle under the sticks to allow airflow into the burning area. The three legs also give the stove more stabilization as it is kind of tall and she was afraid it would tip over with a big pot of chilli on top.

#3 The handles help to carry it when hot. The little access door is used to fill the area inside with high temperature insulation. We used vermiculite - it's light weight, excellent hi-temp insulation, and you can usually buy it at the garden centers.

#4 Sticks ready to burn. The nice thing about the rocket stove is that the fuel is everywhere and it does not have to be 100% dry, seasoned, or any particular type of wood. We have even cooked a meal with straw from the barn. Another good thing about a good hot fire in a rocket stove is that there is almost no telltale smoke if you keep the fire good and hot.

#5 This view shows the location of the air intake baffle. The sticks are placed on top of the baffle and slowly shoved into the fire as they burn up. The air rushes into the stove under the baffle and creates a blow torch effect where the sticks are burning. This does several things - burns very hot with a tiny fire, burns almost anything that is flammable, and burns with enough efficiency that almost no smoke is created.
