Fuel High demand for “light” fuels: gas, petrol.. Availability of HFO Straight Distillate – HFO Blends + Deterioration of Marine Fuel Reduction of the willingness to ignite

Combustion Smallest Particles Largest Surface of Droplets Air Fuel Mechanical Solutions: Turbo Blower Increase Injection Pressure bar

Fuel Problems = Asphaltenes Polar Vanadium empowers the polarity Building of agglomerates of asphaltenes Agglomerates are hard to reverse Let's look at some models and lab tests

Single asphaltene

Four asphaltenes building up to an agglomerate

Disperse Asphaltenes Reduce Polarity Avoid Asphaltenes building up to an agglomerate Excellent dispersing aromatics are Toluene Benzene Let's see the results in a Lab-Test

Specific Fuel Consumption Marintek “A reduction of the ignition delay will generally be beneficial and should result in a more efficient and complete combustion.” Effect on Fuel Consumption

Fuel Consumption Reduction DNV Rapport No Fuel Oil Consumption Tests - M/T “VINGA” “The specific fuel consumption of the engines was reduced with 4% when the combustion catalyst MERGI was applied”

Fuel Consumption Reduction Aboitiz Jebsen, Fuel Management Dep. MV “MILLENIUM DRAGON”, MV “MILLENIUM EAGLE” MV “MILLENIUM TIGER” 6.2% -8.0% reduction in the specific fuel oil consumption

MERGI Combustion Catalyst More questions? Decide Which vessels / engines do you have in mind?

Combustion Catalyst MERGI The fuel saving alone more than pays for the cost of using MERGI Complete Combustion gives: Less maintenance Fuel saving Reduction of CO, NOx,and HC Emissions

Renergi

M/V Bremer Reeder Type of fuel : Diesel Oil. Immediately: clean exhaust and slow steaming was now possible. Changes during 7 weeks : cleaner boiler, rpm raised from 850 to 860. Cylinder temperature: decrease 10 dg. Changes next 6 weeks : cleaner filters, turbo pressure raised 1,75 - 2,0 bar. Max cylinder temp difference : now 15 dg, before 60 dg. Time between cleaning lube oil purifier slowly increased 100% Inspection of injectors : before 2000 h. After 6000 h. Lower fuel consumption. This mainly because it was now possible to run the engine at any load without having soot problems. Back
