“…Aidkins et al reported thermal efficiencies of up to 36% for charcoal cookstoves [26]. For the Gyapa charcoal cookstove, Kshirsagar and Kalamkar reported that some researchers tested many African charcoal stoves, including the Gyapa charcoal cookstove, to calculate the average efficiency of 34% [27]. This result is consistent with our study, which measured thermal efficiency of the Gyapa charcoal cookstove at high power, hot start of 27.3 ± 5.7%.…”

“…Such design features lead to higher efficiency, a hotter flame, and improved combustion. However, there are opportunities to optimize some design characteristics, such as the shape of the stove, the gap between the pot and the burning charcoal, and the size of the grate holes [27]. Optimizing such features can bring about improvement in the air circulation to recycle heat and create the draft needed for more efficient combustion [27].…”

Abstract:In Ghana, about 73% of households rely on solid fuels for cooking. Over 13,000 annual deaths are attributed to exposure to indoor air pollution from inefficient combustion. In this study, assessment of thermal efficiency, emissions, and total global warming impact of three cookstoves commonly used in Ghana was completed using the International Workshop Agreement (IWA) Water Boiling Test (WBT) protocol. Statistical averages of three replicate tests for each cookstove were computed. Thermal efficiency results were: wood-burning cookstove: 12.2 ± 5.00% (Tier 0); coalpot charcoal stove: 23.3 ± 0.73% (Tier 1-2); and Gyapa charcoal cookstove: 30.00 ± 4.63% (Tier 2-3). The wood-burning cookstove emitted more CO, CO 2 , and PM 2.5 than the coalpot charcoal stove and Gyapa charcoal cookstove. The emission factor (EF) for PM 2.5 and the emission rate for the wood-burning cookstove were over four times higher than the coalpot charcoal stove and Gyapa charcoal cookstove. To complete the WBT, the study results showed that, by using the Gyapa charcoal cookstove instead of the wood-burning cookstove, the global warming impact could be potentially reduced by approximately 75% and using the Gyapa charcoal cookstove instead of the coalpot charcoal cookstove by 50%. We conclude that there is the need for awareness, policy, and incentives to enable end-users to switch to, and adopt, Gyapa charcoal cookstoves for increased efficiency and reduced emissions/global warming impact.

“…Compared to the traditional cookstoves, ICS can help achieve 40-75% emissions reduction and nearly 30% fuel efficiency increase [14], [15]. The two most famous categories of ICS are 'Rocket' stoves and 'Gasifier' stoves [16]; with gasifiers performing the most (in terms of fuel efficiency, emission reductions) in all models that utilize wood or charcoal, at the cost of complex configuration.…”

Abstract-In this paper, in an effort towards reducing indoor air pollution (IAP) exposure for cookstove users, an improved biomass cookstove has been proposed. A computational fluid dynamics (CFD) combustion study has been carried out for the proposed cookstove to analyze the combustion and heat transfer behavior using ANSYS Fluent Simulation. The wood combustion phenomenon inside the stove is modelled as gaseous combustion of volatiles generated by pyrolysis. Temperature gradients, velocity profiles and combustion product concentrations are presented. Based on comparison of CFD predicted results with a popular commercial improved cook stove (ICS), it was concluded that the proposed cook stove yields reduced combustion product concentrations as well as faster cooking resulting in better energy efficiency and a health friendly cook stove.
