Quick Answer
For long cooking sessions on rocket stoves, the best fuels are dense, high-energy, and easy to light. Charcoal and wood pellets are suitable options, while wood chips and shavings can be less efficient. Fuel briquettes made from compressed sawdust and binder are another good choice.
Optimal Fuels for Rocket Stoves
When selecting fuels for long cooking sessions on a rocket stove, consider the BTU (British Thermal Unit) content and density of the fuel. Charcoal, for example, has a high BTU content of around 12,000-15,000 BTU per pound, making it an efficient choice. Wood pellets, on the other hand, have a BTU content of approximately 7,000-8,000 BTU per pound, but their compact design allows for easier burning and more consistent heat output.
Preparing and Using Wood Pellets
To get the most out of wood pellets, it’s essential to prepare them properly before use. Simply breaking the pellets into smaller pieces can improve airflow and enhance burning efficiency. When loading the pellets into the rocket stove, create a nest to allow for good airflow and to prevent the pellets from clumping together. A typical loading technique involves placing a handful of smaller pieces at the bottom of the stove and then adding more pellets on top, leaving enough space for air to flow.
Alternative Fuel Options
Fuel briquettes made from compressed sawdust and binder are another excellent option for rocket stoves. These briquettes are designed to burn efficiently and consistently, producing a high amount of heat. When selecting briquettes, look for those with a high BTU content and a moisture level below 10%. This will ensure that the briquettes burn cleanly and produce minimal smoke.
