This is usually an ash insulated double wall metallic stove which
can be built from tin cans or metallic bucket. Elbow style is one
of the key designs of this stove which can be constructed from
metal pipe or ceramic materials. This stove has a 12 cm diameter
and 30 cm high combustion chamber with an insulated skirt
around the pot. To increase the convective heat transfer, a
narrow gap is maintained between the pot and the skirt. The
efficiency varies from 25 to 30 per cent.
High hills.
Portable, low emission and good combustion.
Requirement of smaller size fuel material. Expensive and
requires metal workshop for fabrication.
