Abstract
Jedan od produkta izgaranja fosilnih goriva na brodovima je dušikov oksid. Dušikovi oksidi u brodskim ispušnim plinovima nastaju kada dušik reagira s kisikom pri visokim temperaturama izgaranja. To se dogaĎa gotovo neovisno o vrsti goriva i ovisi o vršnoj temperaturi plamena motora. Rezultirajući dušikov oksid poznat kao NOx, mora se smanjiti prije ispuštanja brodskih ispušnih plinova u atmosferu. U radu su detaljno opisane dvije metode za značajno smanjenje stvaranja NOx u brodskim dizelskim motorima. Recirkulacija ispušnih plinova (EGR), to je unutarnji proces motora koji koristi recirkulaciju ispušnih plinova kako bi se spriječilo stvaranje NOx i Selektivna katalitička redukcija (SCR), metoda naknadne obrade koja koristi katalizator i aditiv za smanjenje NOx koji nastaje u procesu izgaranja. SCR sustav dostupan je u visokotlačnom sustavu i niskotlačnom sustavu.
Abstract (english)
One of the products of burning fossil fuels on ships is nitrogen oxide. Nitrogen oxides in ship exhaust are formed when nitrogen reacts with oxygen at high combustion temperatures. This happens almost independently of the type of fuel and depends on the peak temperature of the engine flame. The resulting nitrogen oxide, known as NOx, must be reduced before the ship's exhaust gases are released into the atmosphere. This paper describes in detail two methods for significantly reducing NOx generation in marine diesel engines. Exhaust Gas Recirculation (EGR), an internal engine process that uses exhaust gas recirculation to prevent NOx formation and Selective Catalytic Reduction (SCR), an aftertreatment method that uses a catalyst and additive to reduce NOx produced in the combustion process. The SCR system is available in high pressure system and low pressure system.
