WebbForbrenningsgassbehandling for NOx med Selective Catalytic Reduction. Teknologien Selective Catalytic Reduction (SCR) reduserer utslipp av nitrogenoksider (NOx) ved hjelp av en katalysator. SCR-teknologi kan oppnå en reduksjon på opptil 95 % av NOx i forbrenningsprosessen og kan dermed oppfylle strengere lovgivning i fremtiden. WebbSNCR is less capital-intensive than SCR. The cost of an SNCR retrofit is $10 to $20/kW, whereas incorporating SNCR into a new boiler is $5 to $10/kW [ 30 ]. The difference is … Webb11 jan. 2024 · This process is known as selective catalytic reduction (SCR). When a catalyst is not used due to sufficient temperatures (1,400 and 2,000 °F [760 and 1,090 °C]) for the reaction to occur, the process is called selective non-catalytic reduction (SNCR) .
