The Applied Research of Emulsified Heavy Fuel Oil Used for the Marine Diesel Engine

Abstract

In order to achieve the application of emulsified fuel oil on the marine,our discussion group developed a set of heavy fuel oil intelligent online emulsifying equipment tested on G6300ZC18B diesel of the ship Ningda "6". And the experimental result shows that, when water mixing ratio ranged from 16% to 24%, emulsification reached good level to apply as marine fuel. When burning emulsified fuel oil, the explosive pressure of diesel engine fluctuated in the range of 1-2Mpa, the exhaust temperature decreased 12°Cand the outlet temperature of cooling water declined slightly, but all the parameters above are in the normal range. The oil consumption decreased by 9.7% and the emission of NOX ,carbon smoke ,and CO reduced by 19.6%,20%,35% respectively.
