Q: Kodi madzi amafunikira chiyani pamadzi omwe amagwiritsidwa ntchito ndi ma jenereta a nthunzi?

A:
Zofunikira zamadzi pamajenereta a nthunzi!
Makhalidwe amadzi a jenereta ya nthunzi nthawi zambiri amayenera kukwaniritsa mfundo izi: monga zolimba zoyimitsidwa <5mg/L, kuuma kwathunthu <5mg/L, mpweya wosungunuka ≤0.1mg/L, PH=7-12, ndi zina zotero. akhoza kukumana m'moyo watsiku ndi tsiku Ubwino wa madzi ndi wochepa kwambiri.
Kukoma kwa madzi ndikofunikira kuti majenereta a nthunzi azigwira bwino ntchito.Njira zolondola komanso zoyenera zoyeretsera madzi zimatha kupewa kukulitsa ndi kuwononga ma boilers a nthunzi, kutalikitsa moyo wautumiki wamajenereta a nthunzi, kuchepetsa kugwiritsa ntchito mphamvu, komanso kupititsa patsogolo phindu lazachuma pamabizinesi.Kenako, tiyeni tiwone momwe madzi amakhudzira pa jenereta ya nthunzi.
Ngakhale kuti madzi achilengedwe amawoneka ngati oyera, amakhala ndi mchere wosiyanasiyana wosungunuka, mchere wa calcium ndi magnesium, mwachitsanzo, zinthu zowuma, zomwe ndi gwero lalikulu la makulitsidwe m'majenereta a nthunzi.
M’madera ena, m’madzimo muli mchere wambiri.Pambuyo pa kutenthedwa ndi kukhazikika ndi jenereta ya nthunzi, alkalinity ya madzi a boiler idzakhala yokwera kwambiri.Ikafika pagulu linalake, imatuluka thovu pamwamba pa evaporation ndipo imakhudza mtundu wa nthunzi.Nthawi zina, kuchuluka kwa alkalinity kumapangitsanso dzimbiri zamchere monga caustic embrittlement pamalo opsinjika maganizo.
Kuonjezera apo, nthawi zambiri pamakhala zonyansa zambiri m'madzi achilengedwe, zomwe zimakhudza kwambiri jenereta ya nthunzi ndizoyimitsidwa zolimba, zinthu za colloidal ndi zinthu zosungunuka.Zinthuzi zimalowa mwachindunji mu jenereta ya nthunzi, zomwe zimakhala zosavuta kuchepetsa mpweya wabwino, komanso zimakhala zosavuta kuziyika mumatope, kutsekereza mapaipi, kuwononga zitsulo kuchokera ku kutentha kwakukulu.Zolimba zoyimitsidwa ndi zinthu za colloidal zimatha kuchotsedwa ndi njira zopangira mankhwala.
Ngati khalidwe la madzi lolowa mu jenereta ya nthunzi likulephera kukwaniritsa zofunikira, lidzakhudza ntchito yowonongeka pang'ono, ndikuyambitsa ngozi monga kuyaka youma ndi kuphulika kwa ng'anjo pazovuta kwambiri.Choncho, ogwiritsa ntchito ayenera kusamala za kayendetsedwe ka madzi pamene akugwiritsa ntchito.
