Abstract
This invention provides a portable combustion device that provides a cleaner combustion, reduces the kindling period, and provides a more efficient overall combustion through the use of a fan that directs a predetermined volume of airflow over the combustible fuel—typically wood or similar cellulose-based biological solids. The combustion device has a combustion chamber with a fuel source. A housing encloses the TEG on the side of the device that generates an electrical output based on a temperature differential between opposing TEG sides. A heat-conducting probe is mounted to the TEG and protrudes into the combustion chamber. The opposing TEG side contacts a heat sink that interacts with ambient air. A fan draws heated air away the heat sink, and forces the air onto the combusting fuel through a plurality of peripheral ports that connect with an air space located between inner and outer walls of the combustion chamber.
