Ukuhlaziywa Kwenzuzo Yomnotho Wokubuyiswa Kokushisa Kwemfucuza

I-air compressor ngokusebenzisa i-air cooler noma i-water cooler ukuze kukhishwe inani elikhulu lokushisa okulahlwayo emvelweni, uma sisebenzisa i-heater yamanzi kagesi kanye ne-diesel boiler ukuze kushiswe lokhu kushisa okudingekayo ugesi namafutha ukuze kubalwe, singalazi ngokucacile inani lalokhu kushisa okulahlwayo.

Ngezansi sisebenzisa i-air compressor engu-100HP (75kW), esebenza amahora angu-8 ngosuku, izinsuku ezingu-300 ngonyaka ukuze ibale.

I-compressor yomoya engu-100HP, amandla angu-75kW, ukugeleza kukawoyela okungu-75L/min, izinga lokushisa likawoyela elingu-80℃, izinga lokushisa lokupholisa elingu-58℃
Ukushisa okukhiqizwayo :75× (80-58) ×0.45×0.85×60=37868kcal/hr

1. Inani lokushisa elidingwa yi-heater yamanzi kagesi ukuze kushiswe i-air compressor unyaka wonke libalwa ngokwe-0.8 yuan nge-kilowatt ihora, kanti ukusebenza kahle kwe-heater yamanzi kagesi kungu-80%, okudingeka kusetshenziswe:
   1 KWH = 1 KWH = 860.42 kcal
   37868 kcal ÷ (860.421 kcal/degree ×0.8) ×0.8 yuan/degree =44 yuan/ihora
   Ngokusekelwe emahoreni angu-8 ngosuku, izinsuku ezingu-300 ngonyaka: 44×8×300=105600 yuan

2. Inani lamakhalori kawoyela wedizili lingu-1×104 kcal ngekhilogramu, kanti ukusebenza kahle okuphelele kwebhoyila likadizili kanye ne-heat exchanger kubalwa ngo-0.75, ngakho-ke inani lamakhalori elisebenzayo likawoyela wedizili elitholakala ngokushiswa kwebhoyila lingaba ngu-7,500kcal ngekhilogramu kawoyela wedizili. Kuthatha amakhilogramu amahlanu edizili ukukhiqiza amakhilogramu angu-37,868.
   Ngokusekelwe emahoreni angu-8 ngosuku, izinsuku ezingu-300 ngonyaka, ama-yuan angu-5.5 ngekhilogramu yedizili
   5 kg/h ×8 amahora/ngosuku ×300 izinsuku/ngonyaka ×5.5 yuan/kg = 66,000 yuan/ngonyaka

Ukulungiswa nokuphathwa kwamabhoyila nakho kudinga abasebenzi besikhathi esigcwele, ngokusho kwama-yuan angu-20,000 ngonyaka, izindleko eziphelele zama-yuan angu-66,000 ngonyaka + ama-yuan angu-20,000 ngonyaka = ama-yuan angu-86,000 ngonyaka. Kungabonakala ukuthi amandla achitheka yi-air compressors aguqulwa abe izindleko zikagesi noma uwoyela minyaka yonke. Uma lokhu kushisa kungasetshenziswa, akukho nzuzo encane ezodalwa.
