Emissions of Industrial Furnaces Burning Diesel Fuel Oils of various Sulfur Contents with NaCl-Contained Atmospheric Air

Abstract

A small furnace associated with an industrial automatic burner was employed in this study to investigate the influences of sulfur content of fuel oils burned with NaCl contained atmospheric air on the emission characteristics of marine or industrial power‐plants. The sulfur contents of 0.3 wt % and 1.0 wt % were considered. Diesel fuel oil A which approximates ASTM No. 2 fuel oil was atomized by the inlet air added with NaCl of 1.5 ppm concentration and thereafter burned within the furnace. It was found that under this burning condition the CO, SO2, and O2 emissions increased with the addition of sulfur in the fuel oil. However, the gas temperature and NOX concentration were affected by the increase of sulfur content to only little extent.
