The Southwestern region of the United States is extremely wealthy in low sulfur coal resources which must be eventually utilized in response to national energy balance priorities. Fly ash and scrubber sludge can be safely disposed of using properly managed techniques to ensure that any potential impact from elements such as boron, molybdenum, or selenium is rendered insignificant. Alternative m...

This study investigates the comparative impact of inherently different biomass and coal ashes on laboratory pilot scale degradation 30 wt% aqueous monoethanolamine (MEA), relevant to post-combustion CO2 capture. Thermal oxidative experiments were carried out at 135 °C 40 respectively with loading (0.5 molCO2/molMEA), without presence ash. Nuclear magnetic resonance (NMR) data is provided for ma...

Zooplankton play an important role in the trophic dynamics of coral reef ecosystems. Detailed vertical and temporal distribution and biomass of zooplankton were evaluated at four heights off the bottom and at six times throughout the diel cycle over a coral reef in the Florida Keys (USA). Zooplankton abundance averaged 4396 +/- 1949 SD individuals m(-3), but temporal and spatial distributions v...

Despite the current advancements in, and increasing use of renewable types energy, approximately 40% world’s electricity is still produced by coal fired power stations. This trend significantly higher in some continents, for example 70% India up to 90% South Africa. In this study fly-bottom ash (FBA) mixture with different component percentages BA (bottom ash)100, FA (fly ash) 25-BA75, FA50-BA5...

Increasing the share of renewable energies is among the prime policies of the European Union. Among the options are the incineration of wood in combined heat and power plants as well as the anaerobic digestion of organic materials to obtain biogas. Both processes leave behind residual matter – wood ash and anaerobic sludge. These residual materials contain chemical elements with considerable fe...

The overall objective of this project is to carry out the fundamental research needed to develop a first-generation, structure-based model of coal char formation and combustion. Current models of char combustion and carbon burnout estimate char behavior from empirical relations based on parent coal properties. With the wide range of fuels of interest to modern combustion systems (international ...

Coal based power plant emitted pollution is responsible for environmental burden of disease (EBD) from solid fuel use (SFU) like combustion of coal or biomass. Environmental pollution due to operation of thermal power plants is also one of the factors for acute lower respiratory infection (ALRI), chronic obstructive pulmonary disease (COPD), lung cancer (from exposure to coal smoke), asthma, tu...
