Combustion performance and emissions of ethyl ester of a waste vegetable oil in a water-cooled furnace

Different techniques for the production of biodiesel from waste vegetable oil

“…The performance of engines fueled with biodiesel produced from waste vegetable oil was extensively covered in the literature (Dorado, 2003a;Tashtoush et al, 2003;Volmajer and Kegl, 2003;Najafi et al, 2007;Lapuerta et al, 2008;Meng et al, 2008;Refaat et al, 2008b;Utlu and Kocak, 2008;Ghobadian et al, 2009) Lapuerta et al (2008 tested two different biodiesel fuels, obtained from waste cooking oils with different previous uses in a diesel commercial engine either pure or in 30 % and 70 % v/v blends with a reference diesel fuel. The main objective of their work was to study the effect of biodiesel blends on particulate emissions, measured in terms of mass, optical effect (smoke opacity) and size distributions.…”

“…Kegl (2008Kegl ( , 2006 indicated that, using biodiesel, harmful emissions (NO x , CO, smoke and HC) can be reduced to some extent by adjusting the injection pump timing properly. Numerous reports in the literature deal with the study of exhaust emissions from engines fueled with biodiesel produced from waste vegetable (Dorado, 2003a;Tashtoush et al, 2003;Sudhir et al, 2007;Lapuerta et al, 2008;Meng et al, 2008;Refaat et al, 2008b;Utlu and Kocak, 2008;Ghobadian et al, 2009). Lapuerta et al (2008) found that by using biodiesel the soot and particulate matter emissions, as well as the particle number concentration, decreased sharply, mainly due to the oxygen content of the biodiesel, which improve the oxygen availability in rich-zone flames in the combustion chamber.…”

Effect of Waste Cooking - Diesel Oils Blends on Performance, Emissions and Combustion Characteristics of Industrial Oil Burner

“…Utilization of waste cooking oil as an alternative fuel in oil burners allows facing the challenges of rising diesel oil prices, reducing gradual depletion of fossil fuel, saving imported fuel from abroad with foreign currency and reduction of exhaust emissions that cause global warming to our planet. Fossil fuel has consumed in different section such as transport, agriculture, commercial, domestic, and industrial sectors for the generation of power mechanical energy [1][2][3][4][5][6][7][8].…”

“…Furthermore, during the startup and shut down process the usage of a more volatile fuel might solve all the practical problems [2,4]. Tashtoush et al investigated combustion characteristics of ethyl ester derived from waste vegetable oil in a boiler [5]. Combustion efficiency, exhaust temperature and levels of regular emissions were carried out across wide range of air to fuel ratios.…”

“…Kiat Ng and Gan made experimental investigations on exhaust emissions and performance at constant fuel flow rate and at various flue gas oxygen contents.They also evaluated CO and NO x emissions levels of palm oil methyl ester and its blend in a combustion chamber at different fuel pressures in the boiler [12,13,14]. Lee et al [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] verified using of B20 soy bean oil methyl ester in a residential oil fired burner. They compared the levels of emissions such as CO and NO of B20 with oil preheating.…”
