Exhaust Gas Cleaning Systems (EGCS), also known as scrubbers, are used in the maritime industry to reduce harmful emissions from ships' exhaust gases. In this context, spray nozzles can be used to help control and manage the exhaust gases in various ways, such as: Spray Absorption: Spray nozzles are used to create a mist of seawater, which is then sprayed into the exhaust gases to absorb and neutralize harmful pollutants, such as sulfur dioxide (SO2) and particulate matter (PM).
 
Cooling: Spray nozzles are used to cool down the exhaust gases to prevent thermal stress and corrosion on the scrubber system and the ship's engine.
 
Scrubbing: Spray nozzles are used to create a scrubbing solution that is used to remove harmful pollutants from the exhaust gases.
 
Wash Water: Spray nozzles are used to wash and clean the scrubber system to remove any build-up of pollutants and maintain the efficiency of the system.
 
Overall, the use of spray nozzles in EGCS is important in reducing harmful emissions from ships and improving air quality. The specific application of spray nozzles in EGCS will depend on the specific design and requirements of the system.
