Clean Air

The impacts of air quality regulations under the Clean Air Act extend beyond directly regulated polluting industries; these regulations also affect the tax bases of local governments. To assess the local fiscal effects of nonattainment regulations under the Clean Air Act, this article analyzes revenue data spanning twenty years for counties throughout the entire United States. Attainment status for ozone, total suspended particulates (TSP), particulate matter smaller than 10 μm (PM10), and sulfur dioxide (SO2) is found to affect local governments' own source or property tax revenues. Nonattainment for these criteria pollutants results in regulations focusing on local industries. These findings indicate declining revenues in ozone, TSP, and PM10 nonattainment areas and suggest suppression of growth during the nonattainment period for SO2.

Simulation Results

The non-dispersive infrared absorption spectrum method is one of the important sulfur dioxide concentration measurement method. If the soot particles attach on the protection windows surface, the original measurement light intensity is attenuated because of the absorption and scattering of the soot particle and the sulfur dioxide concentration measurement accuracy is decreased. The protection window pollution question caused by the monodispersion soot particles is discussed in the paper. The numerical simulation results show that the sulfur dioxide concentration measurement accuracy is related to the protection window pollution. The solution method is brought out and the measurement accuracy can be improved.

The unsteady state computational fluid dynamics model for gas-solid particle flow in industrial scale circulating fluidized bed boiler combining with combustion and desulfurization (using limestone solid sorbent) chemical reactions, both homogeneous and heterogeneous, was developed in this study. The effects of solid sorbent feeding position and solid sorbent particle size on sulfur dioxide concentration were investigated. The results showed that both the solid sorbent feeding position and solid sorbent particle size had an effect on the sulfur dioxide capture. Entering solid sorbent at the upper secondary air position gave lower sulfur dioxide concentration than the one at the lower secondary air position and fuel feed position, respectively. This can be explained by the influence of suitable temperature at the upper secondary air position for desulfurization chemical reaction. About the solid sorbent particle size, the sulfur dioxide capture was the lowest when using the largest solid sorbent particle size due to the system hydrodynamics.
