The nayitrogeni okusayidi mu utsi mpweya wa m'madzi injini jenereta akonzedwa ndi mpweya wopangidwa ndi makutidwe ndi okosijeni wa asafe mu yamphamvu pa kutentha kwambiri, amene makamaka wapangidwa nitric okusayidi ndi nayitrogeni dioxide.Chitetezo cha chilengedwe cha Green Valley chapanga dongosolo la "grvnes" SCR denitration system yochizira ma nitrogen oxides mu mpweya wotayidwa wotayidwa ndi majenereta am'madzi patatha zaka zambiri akufufuza mozama.Pambuyo pa mapangidwe apadera, dongosololi likhoza kuzindikira ntchito yogwira ntchito kwambiri pansi pa kutentha kosasunthika ndi mpweya wabwino;Zigawo zofunika zimatha kupirira zonyansa zomwe zimapezeka mu gasi wotayira pansi ndikuwonetsetsa kuti dongosololi likugwira ntchito mokhazikika.
