“…It can now be seen that the CO2 concentration falls steadily with the fall in the sulfur content of the fuel. These results are in line with those reported by Lin et al [47] where increasing the sulfur content of the fuel reduces the CO2 concentration and combustion efficiency.…”

“…The variance in flame temperatures recorded here are due to the changes in the equivalence ratios and fuel energy densities. This shows that the sulfur content of the fuel does not seem to have a direct impact on the magnitude of the flame temperatures measured because sulfur does little to affect the rate of oxidation of the alkyl groups in the fuel [47]. It is noteworthy to indicate the HFO flame temperatures reported here are lower compared to others [38,48] due to radiation losses.…”

“…The measured SO2 emissions correlate linearly with the sulfur content and increase with increasing sulfur content in the fuel as shown by a number of studies [47,[49][50][51]. An SO2 concentration of 620 ppm was measured for case 1 (3.15 % S) and 48 ppm was measured for case 4 (0.52 % S).…”

“…This showed that when sulfur in the fuel was increased by 6.05 times (3.15/0.52) then the concentration of SO2 in the flue gas increased by two folds (620/48=12.9). Lin et al [47] also showed doubling of SO2 concentrations measured in the flue gas of an industrial furnace when the sulfur content in the fuel was only increased from 0.3 to 1 wt %. Varying the sulfur content did not produce a significant change in the NOx emissions which are at the same levels around 100 ppm for cases 1, 2 and 3, and correspond with the flame temperature distribution reported in Figures.…”

In the present work, an experimental investigation on the effect of sulfur content in heavy fuel oil (HFO) on the gaseous emissions under swirling flame conditions was carried out. The sulfur content in HFO was varied by blending with ultra-low sulfur diesel and four fuel samples containing 3.15, 2.80, 1.97 and 0.52 % sulfur (by mass) were prepared. The fuels were then fired in a high-swirl stabilized, turbulent spray flame. The combustion performance of the fuels was evaluated by measuring flame temperature distribution, gaseous emissions (SOx, NOx, CO, CO2, and flue gas pH) and particulate matter (PM) emissions (morphology, composition, and pH). The results showed a significant reduction in the SO2 emissions and acidity of the flue gas when the sulfur content in the fuel was reduced, as expected. Flue gas SO2 concentration reduced from 620 ppm to 48 ppm when the sulfur content in the fuel was reduced from 3.15 to 0.52 % (by mass). Sulfur balance calculations indicate that nearly 97.5% of the sulfur in the fuel translates into gaseous emissions and the remaining 2.5% appears in PM emissions. Ninety-five percent of gaseous sulfur emissions are SO2, whereas the rest appears as SO3. Varying the sulfur content in the fuel did not have a major impact on the flame temperature distribution or NOx emissions. The morphologies and size distribution of the PM did not change significantly with sulfur content as asphaltenes content of the fuels remained the same.

The effects of sodium sulfate in fuel oil and salty atmospheric air on the emission characteristics of furnaces or boilers burned with emulsified diesel oils are considered in this study. An industrial cylindrical furnace made of stainless steel associated with an automatic oil-fired burner was used for the emission measurements. Both neat diesel oil and emulsified diesel oil with distilled water were used as the tested oils. A homogenizing and emulsifying machine was employed to stir the diesel oil and sodium sulfate powder into a homogeneous oil mixture, and to prepare emulsions of micro-droplets of water dispersed in diesel oil. The experimental results showed that the existence of sodium chloride in atmospheric air enhanced SO2 formation. The use of emulsified diesel oil with 300-ppm sodium sulfate as fuel reduced the burning gas temperature and NOx emission while increased O2 emission. Moreover, the presence of sodium chloride in atmospheric air hindered the completeness of the combustion process and thus resulted in lower burning efficiency and larger excess oxygen emission.
