Most stoves that were tested had better thermal efficiency, but some did not.
Compared with the 3-stone fire, many stoves that were tested had better combustion efficiency, but many did not.
A natural-draft TLUD stove (ARC) had very high efficiency with processed, wood-pellet fuel with low-moisture content.
Some forced-draft (fan) stoves had very low emissions – but not all fan stoves did.
Most natural-draft stoves that were tested showed a bigger improvement (lower emissions) over the 3-stone fire with high moisture fuel than with low-moisture fuel.
A natural-draft TLUD stove (ARC) had very low emissions – but required processed, wood pellet fuel with low-moisture content.
Two rocket stoves were tested at a “medium power” level – and had lower emissions (per energy delivered to cooking pot) than at maximum power.
Charcoal stoves had high emissions of CO and high emissions of PM during start-up.
