“…Numerous laboratory combustion studies, simulating small-scale fires, have demonstrated carbonaceous particles to be emitted predominantly in the submicron particle range (Hedberg et al, 2002;Wardoyo et al, 2007;Levin et al, 2010). Ambient measurements also revealed the dominance of fine aerosols affected by wildfires with high concentrations of OC and EC Amiridis et al, 2012).…”

Aerosol particles significantly impact the regional environment, including climate change, specifically in periods of extensive biomass burning. The major agricultural and domestic combustion emission sources were assessed in nearsource and ambient monitoring campaigns in northwestern Vietnam during the dry season. The composition and microstructure of on-field burning and cooking emissions were analyzed with a variety of techniques. A wide range of observed PM 2.5 mass concentrations was categorized according to the smoke level, supported by the evolution of carbon fractions (OC and EC) as well as ionic species and molecular tracers (K + , levoglucosan, and mannosan). The OC/EC and individual organic compound ratios on days with high smoke levels indicate smoldering combustion of softwood and other local biomass species, impacting aerosol composition at the regional level. Acid and non-acid carbonyls, carboxylates, and aliphatic carbon functionalities in the PM 2.5 size fraction evolved with increasing smoke intensity, together with carbonates in coarse (PM 1-2.5 and PM 2.5-10 ) size fractions, indicating a large impact of smoke emissions and soil lifted up by the intense fires. Biomass burning influence increased the abundance of soot and organic particles in the submicron fraction from 12% at low to 59% and 68% at moderate and high smoke levels, respectively. Smoke micromarkers of local biomass burning source emissions determined the microstructure of ambient aerosols representative for northern Southeast Asia.

“…EF is a metric that quantifies the magnitude of emissions normalized by fuel or energy consumed [31]. Mass EF indicates the emission of a pollutant per unit of dry fuel that is consumed (g pollutant/kg fuel); while energy EF indicated pollutant emissions per unit fuel energy during combustion on a net calorific basis (mg/MJ or kg/TJ) of emission [32,33]. EFs for PM 2.5 , CO 2 , and CO are presented in Table 4.…”

Watching the Smoke Rise Up: Thermal Efficiency, Pollutant Emissions and Global Warming Impact of Three Biomass Cookstoves in Ghana

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.
