SeTa Improved Institutional Firewood Cook-stoves (SeTA-IIFC)



Country:
Tanzania
Why to choose this solution?
SeTa-IIFC is an efficient firewood stove designed for institutions and Small and Medium Enterprises (SMEs) such as schools, colleges, prisons, hotels, restaurants and any other mass cooking places. The cookstoves have thermal efficiency of 54.82 % which means it has the ability to reduce fuel consumption by more than 70% compared to three-stone fireplaces. The reduction of fuel consumption also implies that the stove contributes to a reduction of the institution cooking energy budgets, less time spent in cooking and contributes to environment conservation.
Savings per day or production:
According to evidence from stove users, the SETA-IIFC has the ability to save more than 70 % of fuel. For example, Mnolela Secondary school in Lindi Region before started using SETA-IIFC everyday required about 430 pieces of firewood for preparation of student?s meals, there after the amount dropped to 57 pieces per day. It means that if the 16 inches diameter at breast height (DBH) is harvested for firewood, the institution reduces harvesting of forest from 2 trees to 0.25 trees per day.
Cost in money and in own time to construct:
The SeTA-IIFC available in different sizes. According to the price list of 2020, the stove of 25 litres costs TZS 1,200,000(USD 550), the 50 litres stove is TZS 1,600,000 (USD 730), a stove of 100 litres costs TZS 2,300,000 (USD 1045) and a stove of 200 litres costs TZS 3,500,000 (USD 1,600). The prices also include a stainless steel pot. The fabrication of SeTA-IIFC stove and its pot take about 5 days.
Lifetime:
The durability of SeTA-IIFC is more than 10 years.
Maintenance needed:
The chimney chamber needs regular cleaning to avoid accumulation of soot.
Resources needed in use:
Firewood or wood briquettes as fuel.
Problems and limits:
It requires a special pot which means the pot has to be fabricated together with the stove. Bottom of the stainless steel pot has to be 3mm thickness to ensure its longevity.

Climate effect (if any):
SeTA Improved institutional stove contributes to forest conservation and reduced greenhouse gas emmissions since the amount of firewood used for cooking is reduced.
Where it is used and how many users are there?
Used in Tanzania especially in schools, number of users is more than 3,780.
Why is it successful?
Successful because the stoves have high efficiency attributed by; 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 take place.
If you can make it, a short description, typical problems, materials needed.:
Not relevant, needs a skilled technician
How to make it (if possible):
not relevant
How is it delivered and by whom?
SETa-IIFC is manufactured and delivered to end users by SEECO company
Successful financial model
Support from development partners facilitated development of infrastructure in the working place, purchasing of some machines, marketing, awareness raising and training of the technicians. Income generated from sales of stoves cover the operational costs.
What policies and strategies helped the success?
The Tanzania Biomass Energy Strategy (BEST) and SE4All Action Agenda support production, business and utilization of efficient biomass stoves.
