Quick Answer
A rocket stove made from cinder blocks can be built using basic materials and tools, with a simple design that focuses on efficient combustion and minimal fuel usage.
Materials and Tools
To build a rocket stove from cinder blocks, you will need 6-8 cinder blocks, a metal pipe or flue, a steel or cast iron cook pot support, a cooking pot, and various tools such as a trowel, level, and drill. The blocks should be arranged in a specific pattern to create the combustion chamber, heat exchanger, and chimney. A level is essential to ensure the structure is stable and even.
Construction
Begin by stacking the cinder blocks in a square or rectangular shape, leaving space for the combustion chamber, heat exchanger, and chimney. Use a trowel to fill gaps between the blocks with mortar, and ensure the structure is level. Cut the metal pipe or flue to the desired height and attach it to the top of the structure using bolts or screws. The steel or cast iron cook pot support should be placed inside the heat exchanger, and the cooking pot should be placed on top of it.
Safety Considerations and Usage
The rocket stove should be built in a well-ventilated area, away from flammable materials and overhanging branches. Ensure the stove is at least 3 feet away from any structures or combustible materials. Use dry, seasoned wood for fuel, and maintain the stove regularly to prevent creosote buildup. The stove should be used with caution, and children and pets should be kept at a safe distance. The cooking pot should be placed on the support at an angle to allow for efficient airflow and combustion.
