Kuyeza kwa Ammonia
Ammonia, chinthu chapoizoni komanso chowopsa, ndichofunikira kwambiri pamafakitale ambiri monga kupanga feteleza, kuzizira kwamafakitale ndi kuchepetsa ma nitrogen oxide. Chifukwa chake, kufunikira kwake m'magawo osinthika kumakweza zofunikira kwambiri pachitetezo, kuchita bwino komanso kulondola. Kuyeza molondola kwa kayendedwe ka ammonia pakukonza mafakitale sikumangofunika zaukadaulo, komanso ndikofunikira chitetezo.
Kusankha mita yoyenda bwino ya ammonia kumapangitsa kusiyana pakusamalira zinthu zagasi ndi ammonia zamadzimadzi m'mapaipi a mafakitale. Ndiye deta yolondola ndi zotuluka zodalirika monga 4-20mA, RS485, kapena zizindikiro za pulse zikhoza kuyang'aniridwa ndikujambulidwa kuti zisinthe zenizeni. Othandizira amatha kukhathamiritsa njira potsatira miyezo yachitetezo.
Kuphatikiza pa kuwongolera kolondola m'njira, kuyeza kwa ammonia kumafunika pamalumikizidwe onse kuti achepetse zoopsa zomwe zimayambitsidwa ndi poizoni wa NHx, zomwe zingayambitse kupsa mtima m'maso, mphuno, pakhosi pazigawo zotsika. Ndipo kuyambitsa kwambiri kutupa ndi amayaka kwambiri pa nkhani ya mkulu kukhudzana. Kuwonetsedwa kwa ammonia wokhazikika kungayambitse khungu, kulephera kupuma komanso imfa.
Gesi Ammonia vs. Liquid Ammonia
Ammonia yamafuta ndi yamadzimadzi imasiyana mosiyana ndi ntchito zamafakitale. Kusiyanitsa kodziwika pakati pa mitundu iwiri ya ammonia kumakhudza kagwiridwe, kasungidwe ndi kuyeza mayankho kwambiri. Ammonia wa gasi amapangidwa ndi maatomu a nayitrogeni ndi maatomu a haidrojeni, omwe amawola pakatentha kwambiri kupanga nayitrogeni ndi haidrojeni. Komanso, ammonia wa gasi amasintha kukhala nitric oxide mothandizidwa ndi chothandizira pamikhalidwe yoyenera.
Ammonia wapoizoni wa gaseous ammonia amawononga kwambiri ndipo amakhudzidwa kwambiri ndi chinyezi akafika pamadzi ndi mucous nembanemba. Wopangidwa ndi ammonium hydroxide ndiwowopsa komanso wowopsa ku minofu.
Ammonia yamadzimadzi imabwera chifukwa cha kusungunuka kwa mpweya wa ammonia m'madzi, womwe umadziwika kuti ndi njira yamadzimadzi ya ammonia, yomwe ndi mtundu wamadzimadzi osawoneka bwino komanso onunkhira. Kutentha komwe kungathe kuchitika kuyenera kuchitidwa mosamala pamene ammonia imagwirizana ndi madzi. Ammonia yamadzimadzi imasanduka nthunzi ikawululidwa ndi mpweya, ndikubwerera ku mawonekedwe a mpweya. Khalidwe linanso ndiloti likhoza kusungunuka ku zosungunulira za organic monga ma alcohols ndi ethers mosavuta.
Kuyeza ndi Kuwongolera Zofunikira
Popeza zikuwononga ndi zina zapadera mankhwala katundu wa gasi ammonia, rangeability yoyenera n'kofunika posankha olondola mita otaya popanda kunyengerera kulondola. Kutumiza koyenera kwa ammonia kumafuna mita yoyenda bwino kwambiri. Ndipo katundu wosawononga dzimbiri wa mita yothamanga ndiyofunika kulimbana ndi zovuta zachilengedwe.
Zosintha zogwirira ntchito monga kutentha, kupanikizika ndi kukhuthala ziyenera kuganiziridwa kuti zikhale zokhazikika komanso zolondola. Kulipila kutentha ndi kothandiza posunga kuwerenga kolondola chifukwa cha machitidwe ake osiyanasiyana ndi kutentha.

Kodi Ammonia Amagwiritsidwa Ntchito Motani Pakupanga?
Kugwiritsa ntchito kwambiri ammonia ku USA ndi gwero lamphamvu la nayitrogeni pakukula kwa mbewu. Oposa 80% ammonia amagwiritsidwa ntchito popanga feteleza wolimba kwambiri pantchito yaulimi. Manyowa olimba olimbawo ankatha kuwathira m’nthaka mwachindunji kapena kuwasandutsa mchere wosiyanasiyana wa ammonium. Monga tonse tikudziwa, nitrogen supplementation imakhudza kukula kwa kulima kwakukulu kwambewu.
Gwiritsani ntchito bwino mankhwala apadera a ammonia mu makina oziziritsa a mafakitale. Kutentha kwakukulu kumatha kutengeka kuchokera ku ammonia wa gaseous popanga liquefaction, kufikira cholinga chosunga kutentha m'malo ochepa. Chifukwa chake malo omwe ali pamwambawa amasiya ammonia imodzi mwamafiriji ogwira ntchito kwambiri.
Mwachitsanzo, malo opangira chakudya amafuna mafiriji a mafakitale kuti azitha kutentha. Katundu wowonongeka amakhala watsopano komanso wabwino potsatira mfundo zokhwima za ukhondo ndi chitetezo chazakudya. Zimakondedwa pakati pa mafiriji ena chifukwa cha kuzizira kwake kwakukulu. Kuphatikiza apo, kukhudza kwake kochepa pa chilengedwe kumatsatira zomwe zikuchitika pano pakuchepetsa kutulutsa mpweya wa carbon ndi mtengo wamagetsi.
Ammonia ndikusintha masewera pochepetsa mpweya wa nitrogen oxide. Nthawi zambiri, imayambitsidwa kuti igwirizane ndi ma nitrogen oxides poyesa kuwatembenuza kukhala nayitrogeni wachilengedwe ndi madzi muzosankha zochepetsera (SCR) komanso zochepetsera zosathandizira (SNCR). Ma nitrogen oxides, omwe amathandizira kwambiri pakuwonongeka kwa mpweya ndi mvula ya asidi, amatha kusinthidwa kukhala zinthu zopanda vuto pambuyo pa SCR ndi SNCR.
Zolondolakuyeza kwa ammoniaKumakula kofunikira pamakina opangira mafakitale ndi kukonza mizere kuti asunge kutsata malamulo komanso kuchepetsa NOx, momwe kupatuka pang'ono kungakhudze magwiridwe antchito ndi zotsatira za chilengedwe.
