Introdaksen na ol samting bilong selektiv katalitik ridaksen (SCR) katalis
Ol 'selective catalytic reduction' (SCR) katalis i save yusim wanpela 'reducing agent' long mekim wok wantaim NOx insait long 'flue gas', na kamapim ol 'non-toxic' na 'pollution-fri' N2 na H2O, aninit long wok bilong wanpela 'catalyst'.
Tempereja bilong riaksen i no makim tasol reaksen reit bilong ol riaksen tasol tu reaktiviti bilong SCR katalis. Planti taim, ol bikpela tempereja bilong riaksen i save kamapim hariap riaksen reit na bikpela wok bilong katalis, na dispela i save mekim liklik spes bilong riaksen na volium bilong riaksen long wan wan yunit eria. Taim yumi tingim 'reactant heating', sistem kontrol, na gutpela tempereja bilong katalis, ol tempereja bilong SCR sistem i save stap namel long 320 na 420 digri.
Spes velositi em i wanpela ki disain paramita bilong ol 'selective catalytic reduction' (SCR) katalis. Em i save skelim taim bilong 'flue gas' (wet 'flue gas' aninit long ol standet kondisen) insait long 'catalyst volume', na long sampela mak em i save makim sapos ol 'reactants' i wok gut. Em i save mekim tu 'scouring' bilong 'reactor catalyst framework' na 'friction loss' bilong 'flue gas'.
Kwaliti bilong 'flue gas flow pattern' i makim wok bilong 'catalyst'. Wanpela gutpela 'flue gas flow pattern' i no inap long yusim gut 'catalyst' tasol tu i save daunim 'friction loss'. Long enjiniaring disain, ol i mas tingim gut 'flue gas flow field'. Ol ples bilong putim 'ammonia' i mas gat ol 'turbulent' kondisen long mekim gutpela miks wantaim 'flue gas' na kamapim wanpela klia 'homogeneous flow region'.
