Under intense heat conditions, regular clay bricks can crack or even disintegrate, compromising the structural integrity of your rocket stove. It is essential to choose quality firebricks that can withstand extreme temperatures consistently over time.
Step-by-step instructions for building a brick rocket stove
Although the proper bricks were not used in this build you will still learn how easy it is to build your own DIY rocket stove out of just 16 bricks.
What you will need:
16 bricks or more. You can stack up more layers if you want to increase the draft on your rocket stove and really get it going.
Step 1.
Place 4 and a half bricks on the ground, just like it is shown in the picture. This will be the base of your stove and first layer. You will need to take one of your bricks and cut in half.
To do this you can use a mason hammer, wet saw, mason dry blade on a skill saw or give the brick a good crack on a hard surface in half.
Step 2.
Next place 3 and a half bricks for your next layer like in the picture. You can place the half brick in the same corner or stagger it to the opposite corner to add more structure to the stove.
Step 3.
Next place 4 more bricks to build your next layer and make sure to shift the bricks in the front so you form a bridge. This will be where your rocket stove draws air from and you feed the fire.
Step 4.
Now place another 4 bricks on top and stagger the joints so they are not on top of each other. You are finished with the build. If you want to keep going up with more layers of bricks you can, but this is all you need to get your rocket stove going.
Step 5.
Next get some dry sticks and kindling and light your fire. You might have to blow in the front of the stove to get it to start drafting up the stove chimney to get the rocket burn going.
Step 6.
Once your stove is burning nice it’s time to start cooking. Now make sure to check out your food so you do not burn it because this thing puts off some mean heat right on the bottom of your pan or pot.
