The objective of this research project was to investigate, both qualitatively and quantitatively, the behavior of materials in partially slumped fluidized beds. View windows along the side of the experiment facility made visual observations of bed profiles possible. These observations were recorded on movie films showing the effects of variations...
Coal continues to be burned by direct combustion in packed or moving bed in
small size domestic furnaces, medium size industrial furnaces, as well as small power
stations. Recent stringent restrictions on exhaust emissions call for a better
understanding of the process of combustion of coal in beds.
The present...
The environmental justice framework has been applied to many environmentally negative issues in the past such as toxic storage and disposal facilities, toxic release inventory sites, air quality, transportation, and global climate change. It has not yet been applied to energy production in a quantitative study. This study investigates the...
Illinois coal ground to 80-200 mesh was leached
with a low phosphate, high nitrogen medium containing a
mixture of Thiobacillus ferrooxidans and thiooxidans in a
fluidized bed. Coal slurries of 20-160 g/L were treated
in a 5 cm ID, 9.5 m high continuous loop bioreactor with
crossovers at top and...
We investigate several aspects of the numerical solution of the radiative transfer
equation in the context of coal combustion: the parallel efficiency of two commonly used
opacity models, the sensitivity of turbulent radiation interaction (TRI) effects
to the presence of coal particulate, and an improvement of the order of temporal...
Coal power is the prominent source of energy in the United States (U.S.) and around the world. The byproducts of coal power contain many of the same radioactive nuclides that are found in the local environment just in higher concentrations. With so much of this ash being stockpiled, the amount...
The material properties of the candidate fiber-reinforced composite materials
and different fabrication methods for fiber composites were discussed. The
improvement of the hand lay-up process for polyurethane impregnated Kevlar was
investigated. Testing samples for lab and prototype tests were fabricated by hand lay-up
process. The study showed that fiber composites...
