How the FID Injector can assist an onboard scrubber

5/9/2014

With the new upcoming 2015 sulphur limits (0,1%) in the ECA (Emission Control Areas) shipowners must choose a solution. Shipowners can choose between changing over from HFO to MGO, LNG or installing a scrubber on board. Currently the installation of a scrubber is recognized as best alternative.

Several manufacturers are supplying scrubbers. Most of the scrubbers consist of a wet package to remove the SOx out of the fuel and a dry package to as after treatment to remove the PM (Particle Matter) for example.

Our WFE (water in fuel) system the FID Injector can be used as a pre treatment on board. The water in fuel emulsion with the use of a homogenizer will create an better combustion. With the cleaner and better combustion your engine’s emissions will be reduced. With the FID Injector the PM will be reduced with 60 - 90%. Also every percentage injected water to the fuel will reduce the NOx with 1%.

Please find below the results from an evaluation on board the MV Schieborg.

With a cleaner combustion there will be less maintenance at engine and exhaust.

Currently scrubbers will increase the fuel consumption with an average of 1,5% to 2%. With the FID Injector the fuel consumption will be reduced with approximately 2%. The fuel saving from the FID Injector is achieved by the combination of smaller fuel droplets from the installed homogenizer and the special combustion from the water in fuel emulsion.
