Fuel flexibility gives owners and operators the chance to select the most suitable fuel depending on such factors as local environmental restrictions, fuel price variations, and fuel bunkering availability. In meeting the challenges set by stringent emission regulations another preferable method is switching the main source of power from liquid residual fuels to natural gas.
When a Wärtsilä Dual Fuel engine runs in “gas mode” (natural gas as the primary source of energy), the following targets are achieved: • CO2 emissions are reduced by approximately 20%, thanks to a lower carbon content in natural gas compared to liquid fuels. • NOx emissions are reduced by approximately 80%, thanks to the lean burn combustion process implemented in DF engines. • SOx reduction are reduced by 99% thanks to the engines fuel properties. • Particulates reduction by 95% due also to the engines fuel properties and the combustion efficiency process established.
