A Computational Fluid Dynamics Model to Simulate Wood Combustion
Residential wood stoves and wood heaters are being used by nearly 3 billion people worldwide. In the United States, residential wood heaters are used by only 9 % of the households. However, according to the US EPA, they contribute to around 7 % of the cumulative PM2.5 emissions. Furthermore, …

An Assessment of Indoor Infiltration Parameters for Black Carbon from Residential Wood Combustion and the Spectral Dependence of Light Absorption for Organic Carbon
Black carbon, a proxy for woodsmoke was measured indoors and outdoors for an occupied residence in Cambria, CA during the winter months of 2009. The purpose was to investigate the infiltration parameters: air exchange rate, deposition rate, and penetration factor. The second part of this study …

Parameterizing Climate-Relevant Properties of Biofuel and Biomass Particulate Emissions Based on Combustion Conditions
… conditions (from 20% and 83% RH). Soot from wood combustion did not display any hygroscopic growth directly after generation or when aged for 24 hours with direct co-pollutants. Wood burning soot did display some hygroscopic growth when mixed with a larger mass fraction of hygroscopic …

AI-Based Framework for Identifying Wood Burning Appliances through Chimney Recognition
Estimating the distribution of wood stove appliances is essential for fine-scale air quality management but remains limited by the coarse spatial resolution of survey-based inventories such as the U.S. National Emissions Inventory (NEI). To address this limitation, we proposed a novel computer …

Characterization, seasonality and source apportionment of fine particulate organic matter at urban an d rural sites
… gasoline and diesel-powered vehicles, (2) wood combustion, (3) secondary organic aerosols (SOA) identified using pinic and pinonic acids as markers, (4) plant wax and (5) meat cooking. PMF parameters and residuals were within the acceptable Q-values, indicating valid model performance. The …

Ambient air pollution monitoring, modelling and human health risks in Thulamela Municipality, Vhembe District of Limpopo Province, South Africa
… sources: vehicular emissions and residential wood combustion (RWC). The results indicated annual emissions of 66.3, 1821.7, 21002.6, 2348.7, and 2649.3 tonnes, for SO₂, NOₓ, CO, PM2.5, and PM₁₀, respectively. RWC contributed over 96% of PM2.5 and PM₁₀ emissions, while NOₓ (84%) and SO₂ (60%) …

Characterization of carbonaceous aerosols from biofuel combustion: emissions and climate relevant properties
… to their prevalence in the atmosphere. Biofuel combustion is responsible for nearly 20% of primary BC and OC emissions, but this source is relatively unstudied. Both emissions and optical properties (especially absorption) of carbonaceous aerosols from biofuel combustion need to be better …

Organic Tracer Analyses and Receptor Modeling of PM2.5 in Fairbanks, Alaska
… in nature, including sources such as the combustion of petroleum products and wood. As per the Clean Air Act of 1970, the US EPA has established a National Ambient Air Quality Standard (NAAQS) of 35µg/m3 for a 24 hour average and 15µg/m3 for an annual average of ambient PM2.5 to improve …

Emission quantification associated with firewood usage: A case study of Mangondi village in Limpopo Province, South Africa.
For a long time, fuelwood has been used as an affordable source of energy, available for cooking, lighting, and heating. Fuelwood combusted using informal stoves which are not properly designed are characterized by having low combustion properties, hence, this results in high air pollutant …

Development and characterisation of air-liquid interface exposure systems for cell and tissue cultures
… science, extending to examining the effects of wood combustion and evaluating the impact of occupational and environmental aerosols on human health through inhalation. By bridging laboratory research with real-world applications during the COVID-19 pandemic, this research demonstrates how …

Biomass gasification in small scale plants: experimental and modelling analysis
… are not always environmental friendly process: wood combustion, for example, can be a rather a dirty process that causes the release in air of several dangerous compounds. For those reasons it is important to develop approaches aimed at the use of biomass in a cleanest way, avoiding, whenever …
