The materials used in the construction are metal sheet, metal
rod, clay, mud and cement. Clay, cement and rice husk are kneaded
together. The construction of these stoves except the double
wall metal stove is simple. These models are affordable and are
especially suitable to use with beehive briquettes, and other
fuels such as charcoal and wood. Ignition chamber is below the
grid which separates it from fuel chamber. The fuel burning is
totally dependent on the natural airflow through the combustion
chamber; however there are some measures for controlling airflow
in some stoves.
In case of clay stove with metal ring, the welded metal
reinforcement provides strength to the stove and also acts as the
potholder. The upper portion of the ring is at a height of 5 cm
above the clay level for providing secondary air to the stove. In
double walled metal stove, the space between the walls is insulated
with rice husk, clay, ash etc. The bottom of this chamber has a
