Abstract

The combustion properties of emulsified heavy-oil has been investigated in self-designed combustion equipment, and oil-saving ratio and combustion product composition for emulsified heavy-oil were calculated. The results showed that oil-saving ratio first increased and then decreased with increasing percentage of water added, and the highest oil-saving ratio was 11.60%. The content of NO_x decreased with increasing percentage of water added; the content of NO_x increased with increasing air excess coefficient. For the same air excess coefficient, the content of SO₂ decreased with increasing percentage of water added, it can be attributed to diluting effect of water in flue gas; for the same percentage of water added, the content of SO₂ increased with increasing air excess coefficient, this was because formation mechanism and characteristics of SO₂ and NO_x were different.
