Particulate matter emission during municipal solid waste combustion: Submicron particulates formation mechanism

Wu Yang et al.

Summary: The submicron particles generated from MSW combustion mainly consist of organic components, alkali chlorides, alkali sulfates, and refractory inorganic minerals. The formation of submicron particles includes five modes: condensation, nucleation, accumulation, crystallization, and fragmentation.

On the use of PIV, LII, PAH-PLIF and OH-PLIF for the study of soot formation and flame structure in a swirl stratified premixed ethylene/air flame

Maxime Bouvier et al.

Summary: This study investigates the relationship between flame structure, soot precursors, and soot in swirl stratified premixed ethylene/air flames at atmospheric pressure. Various laser diagnostics are used to obtain extensive information on the mechanisms of formation/consumption of soot and to propose a scenario describing the link between inception, growth, aggregation, and oxidation processes. The data reveal distinct zones for these processes impacted by swirl and stratification intensities.

On the thermophoretic sampling and TEM-based characterisation of soot particles in flames

Maria L. Botero et al.

Summary: This paper presents a multi-scale evaluation of thermophoretic sampling and TEM imaging techniques for characterising soot particles in flames, providing recommendations for capturing representative samples and nano-structural characterization. Experimental observations show the sensitivity of particle characteristics to various factors, highlighting the need for optimization of experimental parameters for different conditions. The study also confirms the impact of beam damage on particle imaging and proposes methods to minimize the damage.

Revealing soot maturity based on multi-wavelength absorption/emission measurements in laminar axisymmetric coflow ethylene diffusion flames

Jerome Yon et al.

Summary: A novel diagnostic method is proposed to characterize the maturity of soot particles in a laminar axisymmetric coflow ethylene diffusion flame based on the spectral dependence of soot absorption function. The method combines line-of-sight attenuation and emission measurements to determine various parameters of soot. The methodology is validated using synthetic spectral signals and applied to analyze experimental data, providing insights into the distribution of soot properties in the flame.
