How does Jeff Holst's Solo Stove system ignite smoke particles?

Answer

Releasing super-heated air through small holes near the top ring

The success of Solo Stove, developed by Jeff Holst, hinges on a sophisticated airflow mechanism that leverages preheating to achieve secondary combustion. Air is drawn into the unit and heated as it travels between the outer casing and the inner wall of the fire pit. Once sufficiently heated, this air is released through a series of meticulously placed small holes situated near the uppermost ring of the fire pit structure. This super-heated air mixes with the unburned gases (smoke) rising from the initial fire, providing the necessary temperature and oxygen to ignite these residual particles. This secondary burn process effectively eliminates the visible smoke plume, transforming what would otherwise be pollution into usable heat and light, thereby making the recreational experience more pleasant for users.
