M'mbuyomu, ndi nyengo ya chifunga yosalekeza m'madera ambiri a dziko, "PM2.5" yakhala mawu otentha kwambiri mu sayansi yotchuka.Chifukwa chachikulu cha "kuphulika" kwa mtengo wa PM2.5 nthawi ino ndi mpweya waukulu wa sulfure dioxide, nitrogen oxides ndi fumbi lopangidwa ndi malasha.Monga imodzi mwazomwe zikuyambitsa kuipitsidwa kwa PM2.5, mpweya wotuluka m'ma boiler oyaka ndi malasha ndiwodziwika kwambiri.Pakati pawo, sulfure dioxide ndi 44%, nitrogen oxides ndi 30%, ndipo fumbi la mafakitale ndi fumbi la utsi pamodzi ndi 26%.Chithandizo cha PM2.5 makamaka mafakitale desulfurization ndi denitrification.Kumbali imodzi, mpweya wokha udzawononga mlengalenga, ndipo kumbali ina, aerosol yopangidwa ndi nitrogen oxides ndi gwero lofunikira la PM2.5.
Chifukwa chake, kuyang'anira mpweya wa ma boiler oyaka moto ndikofunikira kwambiri.Kugwiritsa ntchito Nernst zirconia oxygen analyzer kumatha kuyang'anira bwino kutulutsa kwa sulfure dioxide ndi nitrogen oxides, ndikuchita gawo lofunikira pakuwongolera kuipitsidwa komwe kumachitika chifukwa cha PM2.5.
Tiyeni tiyesetse kubweza thambo la buluu mumzindawu!
