EUROPEAN PROJECT SEMESTER 2

What is the project about?

Plan to achieve the goal:•Scrubber•Catalyst•Boiler•Exhaust Gas Silencer•Funnel•Example exhaust gas cleaning system

Content


To create a catalogue of optimum configurations of exhaust gas cleaning systems for different types of HFO diesel engines to fulfill the IMO 3 criterias

Other main focusses:

•cost of equipment•cost of equipment in action •cost of service•repairing situation and spare parts•place in ship

Goal


IMO 3


Exhaust gas cleaning system?

I would suggest to put also another schema, with more detailed graphics (if exists... )


Exhaust gas cleaning system

Wet exhaust gas cleaning system Dry exhaust gas cleaning systemAn effective and advanced exhaust system must achieve and ensure four main objectives :1 - To reduce noise level by between 40% and 90% through the insertion of silencers end/or silencer-separators;2 - To cool the exhaust, and eject the engine cooling water through the exhaust without excessive back pressure;3 - To site the outlets at the stern of the boat to minimise exhaust fumes on board;4 - To minimize, by the insertion of an adeguate capacity silencer, the risk of water running back up the exhaust and into the engine cylinders, causing serious engine damages.


Time plan

achieve information about system

material, function, cost, dimensions

suppliers of components

examples for existing configurations

create own configurations


ScrubberHow 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.


Scrubber1. Water ph is elevated with

alkalitysodium hydroxide ( NaOH )

2. Entering exhaust gas streamsulphur oxides are capturedand neutralized by scrubbingwater chemically forming sulphates

3. Cleaned exhaust gas exits

4. Water and sulphides return toprocess collection tank

Scrubber (CLOSED LOOP)


Scrubber


Summary of integrated scrubberAvoid 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.

Scrubber


Scrubber•Scrubbing is the cheapest way to comply

•Fresh water scrubber is the only technology to:Make zero effluent discharge possibleBe always in control of reduction efficiencyHave the smallest energy consumptionHave 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.


Scrubber


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


Which fuel ?

Combustion : wood, coal, oil or natural gas

Electric steam boilers : resistance or immersion-type heating elements

Boiler


Fire-tube boiler• Tubes of hot gases running through a sealed container of water

•High-pressure

•Horizontal or vertical

Boiler


Boiler

Water-tube boiler• Tubes of water heated externally by the fire

•High-pressure

•Vertical


Fire-tube boiler• Used on all steam

locomotives

BoilerWater-tube boiler• Used on ships

(marine)


For diesel engine, one or two smaller boilers are used on the ship

Exhaust Gas Silencer


Exhaust Gas SilencerOverview

Typical applicationsabsorption principle

exhaust gas goes through a zylindric flow channel, which is surounded by noise absorbing, thermic high strengh material.

stainless steel/aluminized steel perforized pipes reducing exhaust gas pressure

seamless welding offerts a long service lifestainless steel wool contains high durability

different net shape


Exhaust Gas SilencerFeatures

low skin temperature (LST) design extra layer of packed acustic/thermal insulation that

reduces heat and noiseonly low flow loss

maximum aceptable exhaust gas speed between 20-40m/sec

Easy installation in any positionAdvanced acustical design

Thick wall construction for high transmission lossReduces noxious fumes and odors

Long life serviceWeight from 125-1755kg

Funnel


FunnelFunktions:

removal of smoke and exhaus gas identification of the ship-owner company direct the smoke up in the air to disturb nocody bypass the friction resistance don`t foul the decks and ship structures

Appendagevery high funnels little fins to turbulate the exhaus gas and guide it to the horizontal direction

How does it workGas 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.


FunnelFunnel 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.
