This study was undertaken to better understand the governing processes and reaction conditions under which NOx is produced in Waste to Energy (WtE) boilers. A three dimensional CFD model was created and calculated using the GRI 3.0, 50 species, 309 step detailed chemical kinetic model (DCKM) for methane/ethane combustion. Model results for primary NOx emissions and other pollutants agree well w...

Two methods have been developed for identifying locations in watersheds where vegetative buffers would yield greater benefit for reducing agricultural nonpoint source pollution. The methods were compared and contrasted to evaluate the degree to which they identified the same or different locations within a watershed. The two methods included the terrain analysis-based topographic index, TI, (Qi...
