Validation and sensitivity of a simulated photograph technique for visibility modeling

The Los Alamos Scientific Laboratory (LASL) visibility model is capable of producing simulated before and after pictures that illustrate visual effects of smoke plumes. Although the model has been under development for a few years, until recently there had been very little testing of the model against field experience or testing of sensitivity of the model results to numerical approximations used in the model. Further validation and sensitivity testing of the LASL model began in late 1979. The … more

Thermal energy storage for power generation

Studies strongly indicate that the United States will face widespread electrical power constraints in the 1990s, with most regions of the country experiencing capacity shortages by the year 2000. In many cases, the demand for increased power will occur during intermediate and peak demand periods. Much of this demand is expected to be met by oil- and natural gas-fired Brayton cycle turbines and combined-cycle plants. While natural gas is currently plentiful and reasonably priced, the availabilit… more

Effects of the DOE proposals for new source performance standards for utility boilers firing anthracite coal

Currently, the most important expansion market for anthracite is the electrical utilities/power generation area, where the major competitors are other forms of coal. However, anthracite is more expensive to mine than bituminous coal and requires more expensive boilers and other plant equipment. Advantages of anthracite include its geographic location and, most importantly, its low sulfur content and slightly higher heating value relative to bituminous coal. Because of these factors, anthracite … more

The 1990 Clean Air Act Amendments and the Great Lakes Economy: Challenges and Opportunities

This paper deals with the market for SO{sub 2} emission allowances over time and electric utility compliance choices. For currently high emitting plants ( > 2.5 lb SO{sub 2}/MMBtu), the 1990 Clean Air Act Amendments (CAAA) provide for about twice as many SO{sub 2} allowances to be issued per year in Phase 1 (1995--1999) than in Phase 2. Also, considering the scrubber incentives in Phase 1, there is likely to be substantial emission banking for use in Phase 2. Allowance prices are expected to in… more

Atmospheric oxidation of sulfur dioxide as viewed from power plant and smelter plume studies

An overview is presented of significant historical, recent, and new power plant and smelter plume studies which have been directed at understanding the atmospheric oxidation of sulfur dioxide. It can be concluded that the average rate of oxidation of sulfur dioxide in plumes entering into and mixing with clean air is generally less than 1% per hour but with polluted urban air the rate can be at least twice as fast. In addition, a diurnal variation in the rate is sometimes observed that is near … more
