Previously, with the continuous foggy weather in many parts of the country, “PM2.5” has become the hottest word in popular science. De wichtichste reden foar it "eksploazje" fan 'e PM2.5 Wearde Dizze tiid is de grutte útstjit fan Sulfur Dioxide, stikstof oksiden en stof feroarsake troch stienkoal ferbaarnen. As one of the current sources of PM2.5 pollution, the exhaust gas emissions of coal-fired boilers are very prominent. Among them, sulfur dioxide accounts for 44%, nitrogen oxides account for 30%, and industrial dust and smoke dust together account for 26%. De behanneling fan PM2.5 is fral yndustriële Desulfurisaasje en denitrififikaasje. Oan 'e iene kant sil it gas sels de sfear fersmoargje, en oan' e oare kant, it aerosol foarme troch nitrosol oksides is in wichtige boarne fan PM2.5.
Dêrom is soerstofmonitor fan koalmapers fan stienkoal is heul wichtich. Using Nernst zirconia oxygen analyzer can effectively monitor the emissions of sulfur dioxide and nitrogen oxides, and play an important role in controlling pollution caused by PM2.5.
Litte wy ús bêst dwaan om de blauwe loft nei de stêd werom te jaan!
