“…During the sweep‐down and sweep‐up phases, the stove was operated through several target firepowers by controlling the fuel feed rate and the number of sticks fed into the combustion chamber. Temperature at the combustion chamber outlet (Section S5 of the Supporting Information) was used as a proxy for firepower, because this and other studies have demonstrated a linear relationship between combustion chamber outlet temperature and firepower (Section S4 of the Supporting Information). Although the sensitivity of this measurement to ambient air temperature and thermocouple placement are not well‐understood, a temperature measurement is likely to be more useful than exhaust CO 2 concentration for estimating firepower in a field setting, where total capture hoods are not available.…”

“…Another key limitation is that a multiple‐firepower protocol assumes a relationship between firepower and emissions. There is literature precedence for this relationship; however, the studies that have assessed emissions and firepower have only looked at binary trends (ie, low vs. high firepower) or a single stove‐fuel combination. Thus, this relationship has not been rigorously evaluated.…”

Emissions from solid-fuel cookstoves have been linked to indoor and outdoor air pollution, climate forcing, and human disease. Although task-based laboratory protocols, such as the Water Boiling Test (WBT), overestimate the ability of improved stoves to lower emissions, WBT emissions data are commonly used to benchmark cookstove performance, estimate indoor and outdoor air pollution concentrations, estimate impacts of stove intervention projects, and select stoves for large-scale control trials. Multiple-firepower testing has been proposed as an alternative to the WBT and is the basis for a new standardized protocol (ISO 19867-1:2018); however, data are needed to assess the value of this approach. In this work, we (a) developed a Firepower Sweep Test [FST], (b) compared emissions from the FST, WBT, and in-home cooking, and (c) quantified the relationship between firepower and emissions using correlation analysis and linear model selection. Twenty-three stove-fuel combinations were evaluated. The FST reproduced the range of PM and CO emissions observed in the field, including high emissions events not typically observed under the WBT. Firepower was modestly correlated with emissions, although the relationship varied between stove-fuel combinations. Our results justify incorporating multiple-firepower testing into laboratory-based protocols but demonstrate that firepower alone cannot explain the observed variability in cookstove emissions.

“…Pemodelan keseimbangan termokimia telah digunakan pada proses-proses gasifikasi dengan hasil yang cukup baik (Gautam, 2010). Sedangkan pemodelan efek cerobong pada tungku biomassa secara umum telah dilakukan (Agenbroad, et al 2011a(Agenbroad, et al , 2011b akan tetapi pemodelan dan simulasi pada tungku memasak berbasis gasifikasi masih belum banyak dilakukan. Padahal dengan simulasi tersebut diharapkan desain tungku yang memberikan kinerja proses gasifikasi dan pembakaran yang baik dapat diperoleh.…”

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 227(7), pp. 740-751. doi: 10.1177/0957650913498735 This is the unspecified version of the paper.This version of the publication may differ from the final published version. Permanent AbstractThe provision of affordable electrical power in off-grid rural areas of developing countries is a major challenge but a vital element in the battle to reduce poverty. In response to this need, the SCORE project objective was to integrate a novel technology, thermo-acoustics, into a domestic cooking stove in order to produce an adequate level of electricity supply for families in developing countries whilst also providing efficient cooking. The unit is aimed at the majority of poorer families in developing countries that do not have access to electricity and have little hope of being connected to grid electricity in the near future. The electrical generation function is a vital driver in the adoption of low emissions stoves which significantly reduce health problems from smoke inhalation. This paper describes the design of the cooking part of the stove developed within the framework of the project.Within the wood burning stove, heat released by combustion is first transferred to a thermo-acoustic engine (TAE) to generate electricity, and then to the cooking part. The paper describes the development of the design and construction of the stove to meet the above objectives. This has been progressed through extensive testing of prototype stoves and also through modelling of the heat transfer within the combustion chamber and also for the cooking part of the stoveThe paper presents and compares the results from the test programme and heat transfer modelling and shows how the results are being used to achieve a stove design with an acceptable level of performance. It then concludes with a discussion of how this design might be produced in developing countries.
