乳化燃料油在船舶柴油机上的应用研究

Study of the Applications of Emulsified Fuel Oil in Marine Diesels

为了实现乳化燃料油在船舶上的应用,研发了一套重油在线乳化装置,并在以G6300ZC18B型柴油机为动力的宁大6号运输船上进行实船试验。试验结果表明:当掺水率在16%～24%时,乳化质量好,可作为船舶燃料使用;乳化燃料油燃烧时,柴油机爆发压力在1～2 MPa间波动,排气温度平均下降12℃,冷却水出口温度略有下降,参数变化都处于正常范围内;平均节油率为9.7%,NOx、CO、碳烟排放平均分别降低19.6%、20%、35%。

To realize applications of emulsified fuel oil on ships,a set of heavy oil on-line emusification device was developed and a real-ship test was performed on Ningda No.6 transportation vessel powered by a Model G6300ZC18B diesel engine.The test results show that when the water dilution ratio ranges from 16% to 24%,the fuel oil can attain a good emulsification quality and serve as a kind of fuel oil on ships.When burning the emulsified fuel oil,the diesel engine will have an explosive pressure fluctuating within a range from 1 to 2 MPa,the exhaust gas temperature will drop averagely by 12 ℃ and the cooling water outlet temperature will decline slightly.The above-mentioned parameters are changed in their normal variation range.Moreover,the average oil saving rate reaches 9.7% and NOx,CO and carbon-flue-gas emissions decrease by 19.6%,20% and 35% respectively.
