Heavy fuel oil has been homogenised successfully for many years. This process considerably improves the fuel quality and results in a better combustion.
The homogeniser breaks up the long asphaltene chains in the fuel and enables these to be burnt accordingly. Several ship owners have reported 1% fuel savings and it is also possible to use the FQI to reduce sludge by approx. 50%.
To achieve this two safety-homogenisers have to be installed, one before the separator and one in the booster circuit before the duplex filter. The return of investment should be achieved in less than a year.
However, a homogeniser should not and cannot be used to alter cat-fines. These have to be removed to avoid the fuel acting as a ‚lapping paste’ for the fuel injection parts and cylinders.
Any condensed water from the service tank can however by emulsified into the fuel by the safety-homogeniser to protect fuel injection parts from corroding.
This is not a commercial but I would like to ask for some input from the group if any have any experience in this area that they would like to share,
I have more technical information on the systems that I can forward upon request, please email me directly on firstname.lastname@example.org
But I would prefer to have a here so we all can share information and don't have to invent the deep plate twice
