TEST AND ANALYSIS ON FUELING EMISSION OF B10 KITCHEN WASTE GREASE BIODIESEL FOR SHIP

Using a portable emission test system (PEMS), a domestic river vessel fueled with B10 kitchen waste grease biodiesel (kitchen waste oil biodiesel volume fraction of 10%, diesel volume fraction of 90%) for actual operating condition test. Under the condition of outbound and inbound port, CO, THC, NO_x and PM emission rates fluctuated significantly. In cruise condition, CO、THC and PM emission rates were relatively stable, and NO_x emission fluctuated within a certain range with changes in air flow. Compared with the emission of gaseous and particulate matter in burning pure diesel, when the ship burning burning B10 biodiesel, the CO emission factor decreased by 20.37%, 24.39% and 6.05% in the outbound, cruise and inbound condition, THC decreased by 8.2%, 8.13% and 25.23%, PM decreased by 53.11%, 22.38% and 36.55%, PN decreased by 14.17%, 18.75% and 46.47%; in the port condition, the NO_x emission factor decreased by 54.28% and 40.39%. In cruise condition, NO_x increased by 10.45%. The particle matters emitted by the two fuels all showed a bimodal distribution with the particle size, and the peak particle size was nearly the same. The amount of nuclear particulate matter decreased significantly when fueling B10 biodiesel. The test proved that ships fueled with B10 biodiesel could effectively reduce emissions of gaseous and particulate matters.
