2. Steam plant overview The steam plant of a vessel comprises the following systems: • The steam consumers, which are ship systems that require steam for thermal purposes. • The steam producers, which are devices that produce the steam required by the steam consumers. The most common configuration is one exhaust gas boiler for waste heat recovery on the main engine exhaust line and one oil-fired boiler. • The hotwell tank, which is the water reservoir. It is also used to preheat the water that is delivered to the oil-fired boiler. • The dump condenser, which recovers and condenses any excess steam production. Alfa Laval technical paper 4
