It doesn’t get much easier to build a rocket stove than this:
4 cinder blocks + a gas stove eyelet + 5 minutes
If you want to improve a little on this design add one more block to increase the stove’s height for better a furnace. A chimney that is three to four times the height of the diameter of the intake will give you hotter fire.
Because people in third world countries with little resources have 5 or 6 cinder blocks laying around?? I live in an upper middle class WASP community and don’t have that…
Or you could block off some of the inlet to reduce its size relative to the height of the chimney.
Woow soooo nice
Huh?!! Don’t you know that cinder blocks explode when heated and when they have been moisten (if it has been raining) No thanks!
Well I thought it would be good for apartment dwellers. Thanks Nancy Gill, I did not know they explode.
The fact that bricks and CMUs are so porous also aids in the drying when exposed to heat like a fire. Explosions are the result of rapid heating and water being trapped inside the block turning to steam causing great pressures. If the pressure is great enough, the block will crack, pop or in some cases explode. But since the CMUs are so porous, they typically release the steam as it’s being made by the fire.
Brilliant ! v
A grill does the same thing and is alot safer.
cool but cinder blocks after time will get week from the heat
Explosions can occur if these cinder blocks get to hot !!!!!
