Acoustic agglomeration of power plant fly ash. Final report

Description: The work has shown that acoustic agglomeration at practical acoustic intensities and frequencies is technically and most likely economically viable. The following studies were performed with the listed results: The physics of acoustic agglomeration is complex particularly at the needed high acoustic intensities in the range of 150 to 160 dB and frequencies in the 2500 Hz range. The analytical model which we developed, although not including nonlinear acoustic efforts, agreed with the trends obs… more

Thermal energy storage for power generation

Description: 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

Description: 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

Shawnee test program: TVA Shawnee Test Facility. Technical progress report, April 6-May 6, 1981

Description: The test obtective for April was to evaluate sodium thiosulfate in limestone scrubber slurry as inhibitor of sulfite oxidation. The resulting effect on saturation levels of calcium sulfate (CaSO/sub 4/.2 H/sub 2/O; gypsum) and scaling in the system was of prime importance. As an antioxidant, S/sub 2/O/sub 3//sup =/ functions as a scale inhibitor by reducing SO/sub 4//sup =/, a known scale former. To meet the test objective, the scrubber was operated in a scaling mode as a base case; finally, th… more

Trace elements in the terrestrial environment of a coal-fired powerhouse

Description: A coal-fired powerhouse at the Savannah River Plant, Aiken, South Carolina operated for more than 20 years without electrostatic precipitators and consumed about 360,000,000 kilograms of coal per year. Twenty-nine trace elements were measured in fly ash, and in samples of soil, vegetation, and ground water collected along a 29-km traverse centered on the powerhouse. There were statistically significant effects of the stack releases upon the concentration of Ba, Be, Cu, Hg, Mn, Se, and Sr in soi… more

Potassium vapor topping cycle. Technical progress report, April 1--June 30, 1977

Description: The potassium vapor topping cycle is a concept for increasing the efficiency of the Rankine vapor cycle by raising the peak temperature by employing a potassium vapor cycle with a turbine inlet temperature of 1500 to 1600/sup 0/F (815 to 870/sup 0/C) in which the waste heat rejected from the condensing potassium vapor is transferred to boiling water and steam in a conventional steam cycle. An efficiency of about 50% is calculated for this cycle with a natural circulation potassium boiler fired … more
