Wahi a nā pae mahana like ʻole i ʻae ʻia no ka hana SCR, ua māhele ʻia ia i nā mea hoʻouluulu SCR haʻahaʻa haʻahaʻa (ma kahi o 150 ℃ -260 ℃), me ka hoʻohana nui ʻana i nā mea hoʻouluulu SCR sieve molekala keleawe; Mea hoʻouluulu SCR mahana waena (ma kahi o 260 ℃ -400 ℃), me ka hoʻohana nui ʻana i ka mea hoʻouluulu SCR vanadium; A me nā mea hoʻouluulu SCR wela kiʻekiʻe (ma luna o 300 ℃ -600 ℃), me ka hoʻohana nui ʻana i nā mea hoʻouluulu SCR sieve molekala hao.
1. Kūpono
Ke hoʻohālikelike ʻia me nā mea hoʻoulu kuʻuna, ua hoʻonui ʻia ka pono o ka denitrification e 10-20% ma lalo o nā kūlana like.
2. ʻaʻohe ʻawahia
ʻAʻole loa he mea ʻawahia a ʻino ʻole hoʻi nā mea hoʻouluulu oxide multiphase i hana ʻia me ka hao i ke kaiapuni.
3. Kūpono ke kumukūʻai
ʻO ka ʻāpana nui o ka ʻōpala hana titanium dioxide ka hao, hiki ke hoʻohana ʻia ma ke ʻano he mea maka e hoʻomākaukau ai ma ke kāohi ʻana i ka mahana hana a me nā kūlana ʻē aʻe.
4. Nā palapala noi like ʻole
Hiki ke hana ʻia nā ʻano catalyst kikoʻī e like me nā kūlana kikoʻī o ka pūnaewele denitrification
5. Hoʻololi i kahi ākea o nā mahana
Hiki ke hoʻokō ʻia ka hopena denitrification ma nā mahana kinoea flue mai 200 a 550 degere Celsius, kūpono no nā mahana a puni 350 degere Celsius.

Ua hoʻohana nui ʻia ke kaʻina hana denitrification selective reduction (SCR) me ka hoʻohana ʻana i nā mea hoʻouluulu nitrogen oxide i nā ʻoihana ʻoihana e like me nā mea kanu mana wela, nā mea kanu mana lanahu, nā ʻāpana turbine kinoea, ka puhi ʻōpala, ke kila, nā petrochemicals, a me nā ʻāpana mīkini puhi kūloko.
