A basic experiment was carried out on a new applying method for the main target of mist elimination and desulfurization in the flue gases without need to capital investment particularly onboard. The exhaust gas by heavy fuel oil combustion flows directly the scrubber via funnel, where the emission rate is about 3.6 to 5.6m_N^3/min, and then the cleaned gas is discharged into the atmosphere. The reaction water, supply rate is about 0.02 to 0.036m_N^3/min, made from seawater electrolysis was sprayed to counter-flow of the exhaust gas stream, and neutralized, washed out and diluted the each pollutants in the scrubber. The results showed that the desulfurization of around 95 percent or over could be achieved when using in the high alkaline water, and also leaded to a sufficient reduction in the stability of the each pollutant components and particularly the SOF of PM (Particulate Matter). Furthermore, the advantages of seawater applying onboard include the fact that the operation would be possible without need to capital investment as with high emission control effectiveness.
