N'ebe a na-alụ ọgụ Blue Sky Defence Battle, enwere 'onye isi' ama ama ama na-echekwa ahụike iku ume anyị - ọ bụghị nnukwu ụlọ elu ma ọ bụ usoro njikwa mgbagwoju anya, kamaflue gas desulfurization nozzle (FGD spray nozzle)na dayameta nke naanị ole na ole iri millimeters - ihe a na-adịghị ahụkebe obere akụkụ bụ isi nke arụmọrụ nke usoro desulfurization dum.
Dị ka "akpịrị" nke usoro desulfurization, nozzle kwesịrị iguzogide "nnwale atọ" nke okpomọkụ dị elu, corrosion siri ike, na akwa akwa.
