Why to choose this solution?
SeTa-mkaa is an efficient charcoal-burning stove designed for household cooking purposes. The cookstoves have a thermal efficiency of 50.8 % (TIRDO, 2021), which means they can consume less fuel than traditional metal stoves. Reduction of fuel consumption contributes to a reduction of household cooking-energy budgets.
Savings per day or production:
The material used in SETA-mkaa to conserve heat is a fiber blanket. The efficiency of SETA-mkaa stove is almost twice that of an improved charcoal stove made with clay liner. It can save more than 50% of fuel which would have been required to prepare meals per day.
Cost in money and in own time to construct:
According to the SEECO company 2020 price list, the stove is sold TSh 150,000 (USD 66). Fabrication of one piece of SeTA-mkaa stove is estimated to take half a day.
Lifetime:
The durability of SeTA-mkaa ranges from five to seven years.
Maintenance needed:
May need to repair the firing chamber in case it is overheated and damaged.
Resources needed in use:
Seta mkaa can use either wood charcoal or briquettes.
Problems and limits:
Pot bottoms of less than 2.5mm may melt with time due to high heat produced by the SeTa-mkaa stove.

The design succeeds because of the stoves� high efficiency due to good design for heat transfer, increased surface area for heat exchange, high efficiency of the combustion chamber for reduction of harmful emission, and reduction of heat energy loss by application of ceramic-fibre blanket to areas where heat exchange takes place.
If you can make it, a short description, typical problems, materials needed.:
Some of the materials needed include thick sheet iron and ceramic-fibre blanket. Several types of machines are required for cutting, moulding and joining different parts of the stove.
