Abstract
Many cookstove programmes implemented around
the world aimed to reduce fuel consumption and
pollutant emissions through the dissemination and
adoption of improved cookstoves. A study was carried
out for the design of wood-burning cookstoves
for low-income households in South Africa by
employing user-centred design and co-design/cocreation
approaches. Six designed variants of the
biomass stove were constructed. Water-heating and
emissions tests, using black wattle wood, were conducted
to evaluate them for thermal and emissions
performance. The large hopper stove with two secondary
air inlets ranked highest, with best performance
regarding thermal and emissions parameters.
It outperformed the small hopper stove in time
to boil, heat flux and firepower, although the latter
had higher thermal efficiency values...
