Abstract

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 performance and CO gas emissions
using the Heterogeneous stove Testing Protocol (HTP) developed at the SeTAR
Centre, University of Johannesburg. Results from the testing showed that the
diameter of the pot had little effect on the performance of the tested
kerosene stoves in terms of CO emissions, but it did have an effect on the
thermal efficiency at the high power setting. Power setting was found to
influence the thermal efficiency and combustion performance of all stoves
tested, indicating the need for assessment of the appliances across the full
range of power settings (where feasible). The

pressurised stove had lower CO emissions compared with the wick stoves.
Conversely, the wick stoves depicted lower specific times to boil water and
higher fuel efficiencies. These results provide essential information to
stove designers, regulators and authorities interested in the dissemination
of improved kerosene stoves. The variation of emissions and performance
across the power band may be useful for improving national standards by
correctly characterising novel technologies and improving the design of
existing appliances under different operating conditions. Implications of
improved kerosene stoves are improved health, improved access to modern
energy, reduced fuel consumption and a reduction in energy poverty.
