Abstract

An exhaust gas cleaning device for a watercraft includes at least a particle filter and / or an SCR catalytic converter and a heat exchanger disposed upstream thereof. The heat exchanger is operated with seawater as a cooling medium. The heat exchanger has an exhaust gas inlet side and an exhaust gas outlet side and is suitable for reducing a volumetric flow rate of an exhaust gas between the exhaust gas inlet side and the exhaust gas outlet side by a certain value in a certain temperature range of the exhaust gas at the exhaust gas inlet side. A watercraft and a method for operating an exhaust gas cleaning device for a watercraft are also provided.

Description

technical field

[0001] The invention relates to an exhaust emission control device for a vessel and a method for operating an exhaust emission control device. Background technique

[0002] As a rule, boats have large-volume internal combustion engines and correspondingly designed exhaust systems. Due to increasingly stringent permissible emission quantities involving internal combustion engines or drive units on board ships, complex exhaust emission control devices are required in many cases, even for ships. Due to the high exhaust gas throughput (volume flow / mass flow), a correspondingly bulky exhaust emission control device likewise has to be provided, which increases the costs accordingly. Suitable exhaust emission control devices, such as oxidation catalytic converters, storage units, particle filters and SCR systems (hydrolytic catalytic converters and SCR catalytic converters), on the one hand have to be large in size and on the other hand have to provide a large amou...
