Comparative analysis and estimation of amounts of exhaust gas waste heat from the Tier III-compliant dual-fuel low-speed marine main engines

Existing and future IMO restrictions on emission of harmful substances contained in exhaust gas have introduced an obligation to implement technical solutions reduce NOX, SOX CO2 emissions. Reduction NOX emissions has been achieved by systems (i.e. SCR EGR) ensuring Tier III-compliant composition. EGR also affected the amount waste heat. Therefore reduction mostly dependent available heat produce electricity using recovery generator unit instead medium-speed diesel generating set. Comparative analysis amounts LNG MGO modes under ISO ambient conditions carried out with particular emphasis impact different variants systems. Formulae estimate determined least squares method.
