Efficient Fish Frying Firewood Stove (SeTa-Kaanga)

Why to choose this solution?
SeTa Kaanga is an efficient firewood stove designed for fish frying purposes. Fish is a product that can spoil very fast particularly in the tropical heat along the coastal districts. Fish frying in Tanzania is one of the industries known to consume a significant volume of wood. Firewood is one of the main sources of energy for fish processing. The type of stoves used is open fire which consumes a lot of firewood. SeTa Kaanga stove has thermal efficiency ranging from 50 to 60% as opposed to a three stone fire place with thermal efficiency ranging from 10 to 15%. SeTa Kaanga stove reduces firewood consumption by 50% and also has the ability to take smoke out from the kitchen. Furthermore, SeTa Kaanga reduces burning risk to users.
Savings per day or production:
SeTa Kaanga reduces firewood consumption by 50% per day compared to three stone fire places.
Cost in money and in own time to construct:
SeTa Kaanga can be constructed in different sizes. It is built using burnt bricks, sand, lime, cement and wire mash. Local masons charge labour between 60,000 Tsh to 75,000 Tshs (USD 26-32) per stove. Materials for constructing SeTa Kaanga of 100 centimetre width cost about 250,000 Tsh (USD 108). Construction takes about two to three days.
SeTa Kaanga can last for more than three years if properly used and maintained.
Maintenance needed:
The chimney chamber needs to be cleaned regularly to avoid tar clogging and requires occasional repair in case of cracks in the stove.
Resources needed in use:
The stove use firewood.
Problems and limits:
Requires dry firewood chopped into medium size pieces. Performance of the stove might be affected if dimensions are not observed and followed during construction.
Where and how can you get it or make it?
"The stove is available in Tanzania, designed and promoted by TaTEDO."
Skills needed to produce, install. maintenance, use:
Construction of SeTa Kaanga stove requires skilled masons. Major repair and maintenance may also require skilled masons otherwise the trained operator may clean the chimney and do minor maintenance of the stove.

Climate effect (if any):
Contributes to reducing GHGs emissions from wood sources. Reduces the amount of firewood required for fish frying leading to a reduced number of trees harvested for firewood demands.
Where it is used and how many users are there?
Used in coast region of Tanzania, especially in Kilwa Masoko, Somanga and Mtwara where fish business is among the main economic activities. SeTa Kaanga is used by more than 1,000 fish processors.
Why is it successful?
SeTa Kaanga achieves efficient firewood combustion and maximizes heat transfer to the fish frying pan.

How to make it (if possible):
How is it delivered and by whom?
Main actors include TaTEDO, local trained artisans, fish processors and beach management units (BMU). BMU is involved in mobilizing the fish processors within their localities and monitoring the performance of the stove. TaTEDO is responsible in awareness raising, demonstration and capacity building of ToTs on construction and maintenance of the stove. Whenever new inquiries received, the trained ToTs becomes responsible in providing the service.
Successful financial model
Grant and subsidies through project was used to disseminate the SeTa Kaanga during its introduction to the local communities.
What policies and strategies helped the success?
The role of improved cook stove is realised in national Energy policy of 2015, Tanzania SE4ALL action agenda, Draft Biomass Energy strategy (BEST) and the draft Energy Efficiency Strategy of 2018. Also there has been support from various development partners.
