  9. Scrubber How does it work? Sulphur Oxides SOx (SO2) dissolves within water vapour forming airborne acids. What is it made of? Formed from sulphur contained in oil during combustion and refining processes. EUROPEAN PROJECT SEMESTER

  14. Scrubber EUROPEAN PROJECT SEMESTER

  15. Scrubber Summary of integrated scrubber • Avoid increased exhaust gas back pressure caused by cleaning devices. • Reduce the amount of equipment needed for SOx-cleaning of exhaust gases from all relevant combustion units onboard. • Provide a higher cleaning performance in port conditions where the total flow of exhaust gases is smaller than in normal seagoing conditions, utilising such higher performance as inherent in some exhaust gas cleaning devices when operated at reduced exhaust gas flow. Thus all combustion units can use the same fuel in all areas and all conditions. EUROPEAN PROJECT SEMESTER

  16. Scrubber • Scrubbing is the cheapest way to comply • Fresh water scrubber is the only technology to: • Make zero effluent discharge possible • Be always in control of reduction efficiency • Have the smallest energy consumption • Have no creation of CO2 caused by neutralization process • Wärtsilä fresh water scrubber solutions are fit for new building and retrofit, for any engines and boilers’ brands. EUROPEAN PROJECT SEMESTER

  18. Boiler What is the purpose ? To obtain boiled water by heating water or other fluid in a closed vessel. What is it made of ? Made of steel or wrought iron, assembly by rivetting EUROPEAN PROJECT SEMESTER

  19. Boiler Which fuel ? Combustion : wood, coal, oil or natural gas Electric steam boilers : resistance or immersion-type heating elements EUROPEAN PROJECT SEMESTER

  20. Boiler Fire-tube boiler • Tubes of hot gases running through a sealed container of water • High-pressure • Horizontal or vertical EUROPEAN PROJECT SEMESTER

  21. Boiler Water-tube boiler • Tubes of water heated externally by the fire • High-pressure • Vertical EUROPEAN PROJECT SEMESTER

  22. Boiler Fire-tube boiler • Used on all steam locomotives Water-tube boiler • Usedonships (marine) EUROPEAN PROJECT SEMESTER

  23. Boiler on ships For diesel engine, one or twosmaller boilers are used on the ship EUROPEAN PROJECT SEMESTER

  24. Boiler on ships Suppliers • Aalborg Industries • Mitsubishi Heavy Industries, LTD • Kangrim • Garioni Naval • Chromalox EUROPEAN PROJECT SEMESTER

  25. Exhaust Gas Silencer EUROPEAN PROJECT SEMESTER

  26. Exhaust Gas Silencer Overview Typicalapplications absorptionprinciple exhaust gas goes through a zylindric flow channel, which is surounded by noise absorbing, thermic high strengh material. stainlesssteel/aluminizedsteel perforized pipes reducing exhaust gas pressure seamless welding offerts a long service life stainless steel wool contains high durability different net shape EUROPEAN PROJECT SEMESTER

  27. Exhaust Gas Silencer Features lowskintemperature (LST) design extra layer of packed acustic/thermal insulation that reduces heat and noise only low flow loss maximum aceptable exhaust gas speed between 20-40m/sec Easy installation in any position Advanced acustical design Thick wall construction for high transmission loss Reduces noxious fumes and odors Long life service Weight from 125-1755kg EUROPEAN PROJECT SEMESTER

  29. Funnel EUROPEAN PROJECT SEMESTER

  30. Funnel Funktions: removal of smoke and exhaus gasidentification of the ship-owner companydirect the smoke up in the air to disturb nocodybypass the friction resistance don`t foul the decks and ship structures Appendage very high funnelslittle fins to turbulate the exhaus gas and guide it to the horizontal direction How does it work Gas inside is warm and therefor have a lower weight than the cold air outside.So they have to climp up the funnel pipe. They build a room with less air pressure, in which the cold air is going. Gauge pressure is about 0,0009-0,0015 bar, depends on the resistance. EUROPEAN PROJECT SEMESTER

  31. Funnel Funnel area The required funnel cross-sectional area is determined by the volume of exhaust gases produced by the propulsion plant. Often this area is too great for a single funnel. Early steam vessels needed multiple funnels had 5 when launched, but as efficiency increased new machinery needed fewer funnels. Suppliers Ditco EUROPEAN PROJECT SEMESTER
