Abstract: Two commercially available water-in-oil emulsifiers were tested to determine the effect of water/residual oil emulsions on air pollutant emissions and thermal efficiency of a packaged boiler. Of ...

Abstract: Two pilot-scale (0.73 MW or 2.5 × 106 Btu/hr) firetube package boilers were retrofitted for fuel oil reburning application for NOx emission control. When firing distillate fuel oil (0.01 ...

Abstract: A vertically fired natural-draft petroleum-refinery crude-oil process heater was modified to reduce oxides of nitrogen (NOx ) emissions by installing staged combustion air lances. Baseline NO ...

Abstract: The performance and air pollution emissions of an experimental water/oil emulsion burner are presented. The burner was fired with two residual oils at selected emulsion water fractions. In ...

Abstract: The use of combustion modification has enabled many utility boilers to meet the emission standards for NOx . Its usefulness in reducing NOx emissions from industrial boilers (ranging from 11 ...
