Research has shown that there is a clear link between emissions from inefficient domestic cooking appliances and the prevalence of respiratory infections and cardiovascular diseases. This has prompted the need for the development and dissemination of efficient clean cookstoves for cooking and heating purposes. Although liquid fuels are rated cleaner than traditional solid fuels, their combustion in...
Despite more than 87% households in South Africa being electrified, domestic coal combustion still remain a major source of cooking and heating in low-income households on the Highveld. A majority of low-income households burn coal in informal braziers-imbaulas-constructed from 25 L metal drums with holes punched around the sides. These imbaula stoves are hand manufactured without any standard reference...
The combustion of kerosene fuel in poorly designed cookstoves is a major domestic source of poor indoor air quality and burn injuries in the developing world. It is argued that these challenges are best addressed by the development and dissemination of clean, safe and efficient cookstoves. In this study, three kerosene stoves including two wick stoves and one pressurised stove were tested for thermal...
This paper aims to highlight the potential and prospects of bio-fuel geysers in South Africa, notably the Shiza Manzi geyser. The geyser is compared to the imbaula and an improved StoveTec bio-fuel stove using the SeTAR Centre heterogeneous stove testing protocol. The geyser gave a high power of 23 kW and an adequate thermal efficiency of 36%, boiling 20 litres of water in an average of 12-minutes...
