Binciken fa'idar tattalin arziƙi na iskar oxygen wadatar konewa
Matsayin yanayin: don 5t / h Cupola, lokacin aiki na shekara shine 3600h, rabon coke na farko shine 1:10, kuma yawan amfanin ƙasa shine 70%.Lissafin fa'idar tattalin arziki:
Ajiye 15% na coke (farashin coke shine 2000 yuan / T) 5 * 3600 / 70% * (1:10) * 15% * 2000 = 770000 yuan / shekara.

Yi amfani da oxygen 160nm3 / h (farashin oxygen shine 1.0 yuan / m3) 160 * 3600 * 1.0 = 576000 yuan / shekara

Kimanin yuan 150000 an saka hannun jari a cikin kayan aikin, wanda shine saka hannun jari na lokaci guda (wanda aka ɗauka)

Ƙarfin ƙarfin ya karu da 15%.5 * 3600 * 15% = 2700t / shekara

Ƙarshe: fa'idar tattalin arziƙin kai tsaye ita ce adana farashin samarwa na yuan 60000 a kowace shekara da haɓaka ƙarfin samarwa da 2700t / shekara.Babban haɗin kai da fa'idodin kai tsaye suna da yawa sosai!
