ABSTRACT
The work performed by the marine engines to keep the plant running for propelling a ship requires the burning of fuel. The energy converted inside the cylinder of the engine is not a 100% efficient conversion as part of it is lost in the form of exhaust gases. The exhaust gas system of modern marine engines is designed in such a way that the unused gases coming out of the cylinders are redirected to the turbocharger and exhaust gas boiler (EGB) to recover this waste energy. To use the maximum energy from the waste gases, the exhaust system consists of various components, including the exhaust gas pipes, EGB, the silencer, the spark arrester, and a series of expansion joints. In this chapter, we will briefly discuss the role and function of each of these main components.
