When the fuel used is heavy oil, then the flue gases except for their high content in soot usually contain unburnt masses which are particularly damaging for the atmosphere and the environment.
A solution to this problem are soot accumulators, which through a special layout of fins retain a big part of the soot and unburnt masses and as a result the gases driven to the atmosphere are cleaner.

- Large inspection ports
