PM Formation-Decomposition and Combustion Characteristecs of Heavy Fuel Emulsion Oil

Marine fuel oil differs from fuel oils for automobiles and energy-saving plants especially in its properties. As a low-grade fuel oil, it is not only mainly composed of hydrocarbon but also contains a great quantity of sulfur, nitrogen and residual carbon contents. PM components formed by reaction of combustion have not been thoroughly examined. As sea transportation increases, it becomes necessary to grasp the present state of PMs exhausted from vessels as an air-pollutant and it needs to take a research and development to reduce them. Accordingly, relevant organizations including International Maritime Organization (IMO) continue to consider regulations. This study is intended to check a temperature of the flame to raise by burning Marine Diesel Oil(C heavy oil) and Emulsion Fuel oil in a boiler, also measured the concentration of DS and SOF after collecting the PM(Particulate Matters). Especially, SOF are analyzed by using high performance liquid chromatography(HPLC). In this experiment we use additive, itis inorganic matter that cause of non hazardous. That is harmful at any temperature(15℃~100℃) and it make the oil and water not separate. The water emulsion diameter is about 30㎛. The reaction of combustion was promoted by Emulsion and the concentration of the PAHs got low with NO, CO₂, SO₂, DS, SOF.
