Particle growth in the plumes of coal‐fired power plants

The lack of detectable particle volume enhancements in the SO 2 ‐poor but NO y ‐rich Cumberland plume is strong evidence that other compounds (e.g., HNO 3 and low‐volatility organics) do not, in the absence of sulfur compounds, play a significant role in fine‐particle mass growth in the plumes from coal‐fired power generation stations.

Particle growth in urban and industrial plumes in Texas

Particle size distributions and gas-phase particle precursors and tracer species were measured aboard an aircraft in the plumes downwind from industrial and urban sources in the vicinity of Houston, TX during the daytime in late August and early September 2000. Plumes originating from the Parish gas-fired and coal-fired power plant, petrochemical industries along the

Nucleation and growth of sulfate aerosol in coal-fired

New-particle formation in the plumes of coal-fired power plants and other anthropogenic sulfur sources may be an important source of particles in the atmosphere. It remains unclear, however, how best to reproduce this formation in global and regional aerosol models with grid-box lengths that are 10s of kilometers and larger. The predictive power of these models is thus limited by

Aerosol nucleation in coal-fired power-plant plumes: AIP

Apr 26, 2013· New-particle nucleation within coal-fired power-plant plumes can have large effects on particle number concentrations, particularly near source regions, with implications for human health and climate. In order to resolve the formation and growth of particles in these plumes, we have integrated TwO-Moment Aerosol Sectional (TOMAS) microphysics in the

The effect of coal-fired power-plant SO 2 and NO x control

Nucleation in coal-fired power-plant plumes can greatly contribute to particle number concentrations near source regions. The changing emissions rates of SO 2 and NO x due to pollution-control technologies over recent decades may have had a significant effect on aerosol formation and growth in the plumes, with ultimate implications for climate and human health.

Sulfate aerosol production and growth in coal‐operated

The oxidation of SO 2 and the resultant aerosol growth kinetics are inferred from airborne measurements of the number concentrations and size distributions of pure sulfate and mixed particles within the coal‐fired Keystone power plant plume in western Pennsylvania. Measurements of aerosol concentrations in nine distinct size ranges between 0.01–2.0 μm
