Ngokukhula kokukhathazeka komhlaba wonke mayelana nokuvikelwa kwemvelo, ukunciphisa intuthu engcolisayo sekuyindaba ebalulekile embonini yokuphehla udizili. Ukusetshenziswa kobuchwepheshe bokwelapha igesi yomsila kubaluleke kakhulu ukunciphisa ukukhishwa kwamagesi ayingozi. Leli phepha lizoxoxa ngokubalulekaqeda igesiukwelashwa kweamasethi generator dieselkanye nendlela yokunciphisa ngempumelelo ukungcola okuyingozi.
Okokuqala, kudingeka siqonde izinto eziyingozi ku-exhaust gasamajeneretha edizili. Amajeneretha edizilikhiqiza uhla lwamagesi ayingozi lapho eshisa udizili, okuhlanganisa i-nitrogen oxides (NOx), i-sulphur dioxide (SO2), i-particulate matter (PM) ne-carbon monoxide (CO). Lezi zinto eziyingozi zingaba yingozi empilweni yomuntu kanye nemvelo.
Ukuze kuncishiswe ukungcola okuyingozi,amasethi generator dieselisidingo sokwamukela ubuchwepheshe bokwelapha igesi yomsila. Phakathi kobuchwepheshe obuvame kakhulu i-selective catalytic reduction (SCR) kanye ne-particulate traps (DPF). Ubuchwepheshe be-SCR buguqula ama-nitrogen oxide abe yi-nitrogen namanzi angenabungozi ngokujova isisombululo se-urea kugesi yokukhipha umoya. Ubuchwepheshe be-DPF bucupha futhi buhlunge izinhlayiya ukuze zingangeni emkhathini.
Ngaphezu kobuchwepheshe bokwelapha igesi ephumayo, ukusebenza nokugcinwa kwamasethi ejeneretha yedizili nakho kudlala indima ebalulekile ekwehliseni ukungcola okuyingozi. Okokuqala, ukugcinwa njalo nokuhlanza i-isethi yejenerethaingaqinisekisa ukusebenza kwayo okuvamile futhi inciphise ukukhishwa kwegesi. Okwesibili, ukukhetha kukaphethiloli okunengqondo nakho kunganciphisa ukukhishwa okuyingozi. Ukusetshenziswa kwedizili enesulfure ephansi kanye nezithasiselo kunganciphisa i-sulphur dioxide kanye nokukhishwa kwezinhlayiya ze-particle. Ukwengeza, ukulawulwa komthwalo ozwakalayo kanye namasu okusebenza nakho kunganciphisa ukungcola okuyingozi.
Mayelana nokwelashwa kwegesi ephumayo yeamasethi generator diesel, ukusekela nokuqondisa kukahulumeni nezinhlangano ezivikela imvelo nakho kunendima ebalulekile. Uhulumeni angakwazi ukwenza imithethonqubo efanele kanye namazinga adingekayoamasethi generator dieselukusebenzisa ubuchwepheshe bokwelapha igesi ephumayo, nokubeka izinhlawulo kumayunithi angahlangabezani namazinga. Izinhlangano zezemvelo zinganikeza ukwesekwa kwezobuchwepheshe kanye nokumela ukukhuthaza ukuthuthukiswa kweisethi ye-diesel generatorimboni ngendlela ehambisana nemvelo.
Kafushane, ukwelashwa kwegesi ephumayo kwamasethi ejeneretha yedizili kubalulekile ukuze kuncishiswe ukukhishwa okuyingozi. Ngokusetshenziswa kobuchwepheshe bokwelapha igesi ephumayo, ukusebenza kahle nokugcinwa kahle kwamasethi ejeneretha, nokusekelwa ohulumeni nezinhlangano zezemvelo, singanciphisa ngempumelelo ukukhishwa okuyingozi kwamasethi ejeneretha kadizili kanyevikela imvelokanye nempilo yomuntu.
