Charcoal stoves

In areas where charcoal is the predominant fuel, simple stoves have evolved to take advantage of its special burning characteristics. They are usually one pot cookers and usually include a grate on which the charcoal is placed, an opening for air intake below the grate, and supports for the pot. A good charcoal stove places the pot as close to the burning embers as possible without actually touching them. In this way maximum advantage can be taken of the fire's radiative heat. Since burning charcoal emits no smoke and little hot gases, most heat is transferred by radiation and conduction.

Charcoal tends to pack tightly. To supply the fire with adequate oxygen for combustion, air intake is best assured from below through a grate (Fig. 7-78).
