Exhaust Gas Cleaning System (EGCS)
A system that includes one or more EGC units and which is based on technology that uses a wet cleaning medium for the reduction of SOX from an exhaust gas stream from installed fuel oil combustion unit(s), operating in either open-loop or closed-loop mode. A hybrid EGCS can operate in both open-loop mode and closed-loop mode. Several EGC units may utilize a common uptake system with a single exhaust gas monitoring system. Several EGC units may utilize a common washwater, water supply, treatment and/or overboard system and discharge water monitoring equipment.
Device within which exhaust gas and cleaning medium are mixed. An EGC unit may have a single or multiple fuel oil combustion unit(s) connected to it.
Water entering the ship as a cleaning medium for an EGC unit.
Any water from an EGCS to be discharged overboard.
EGCS operating mode in which the washwater, typically seawater, is passed through the EGC unit only once before it is being discharged overboard as discharge water.
EGCS operating mode in which the washwater is passed several times through the EGC unit.
Any engine, boiler, gas turbine, or other fuel oil fired equipment, excluding shipboard incinerators.
