Ngaphambilini, ngesimo sezulu esinenkungu esiqhubekayo ezingxenyeni eziningi zezwe, i-“PM2.5” isibe igama elishisa kakhulu kusayensi edumile.Isizathu esiyinhloko “sokuqhuma” kwenani le-PM2.5 ngalesi sikhathi ukukhishwa okukhulu kwe-sulphur dioxide, ama-nitrogen oxides nothuli olubangelwa ukushiswa kwamalahle.Njengomunye wemithombo yamanje yokunukubezeka kwe-PM2.5, ukukhishwa kwegesi ekhishwayo yamabhoyela abasebenzisa amalahle kugqame kakhulu.Phakathi kwazo, i-sulphur dioxide yenza ama-44%, ama-nitrogen oxides enza ama-30%, kanti uthuli lwezimboni nothuli lwentuthu ndawonye lwenza u-26%.Ukwelashwa kwe-PM2.5 ikakhulukazi ukuchithwa kwe-industrial desulfurization kanye ne-denitrification.Ngakolunye uhlangothi, igesi ngokwayo izongcolisa umkhathi, futhi ngakolunye uhlangothi, i-aerosol eyakhiwe ngama-nitrogen oxides iwumthombo obalulekile we-PM2.5.
Ngakho-ke, ukuqapha umoya-mpilo wama-boilers asebenza ngamalahle kubaluleke kakhulu.Ukusebenzisa i-Nernst zirconia oxygen analyzer kungaqapha ngempumelelo ukukhishwa kwe-sulphur dioxide nama-nitrogen oxides, futhi kudlale indima ebalulekile ekulawuleni ukungcola okubangelwa yi-PM2.5.
Asenze konke okusemandleni ethu ukubuyisela isibhakabhaka esiluhlaza edolobheni!
