In current study, the water phase of emulsified fuel contained 1 vol% methanol, 10 4 vol% isopropyl alcohol (IPA), and 95 vol% water, which were simulated to the specific industrial 11 solvent-containing wastewater (SCW). The SCW fractions in emulsified fuel were optimized by 12 thermal, centrifugal, and 14-day standing stability tests. The emulsion M1P4-10 with 10 vol% SCW 13 was found to be no separation, the smallest and the most homogeneous water in oil (W/O) droplets 14 after stability tests. In industrial boiler tests, the micro-explosion and tinder effect of solvent 15 contents improved 10~33% boiler efficiency and reduced 5~31% fuel consumptions by using 16 M1P4-10. The emissions of traditional pollutant SO , PM, CO, HC, and NO were decreased by x x 17 3.3~7.1, 41~85, 89~93, 91~60, and 3.3~23%, respectively. Additionally, the emission levels of total 18 PAHs and total BaPeq were also reduced 37.7 and 61.8%, respectively, by the use of M1P4-10. 19 Consequently, the solvent-containing wastewater emulsified heavy fuel oil could effectively 20 promote the boiler efficiency and reduce the pollutant emissions. 21 Keywords: emulsification; heavy fuel oil; thermal efficiency; emissions; PAHs 22 23
