Iyo ichangoburwa Nernst 1735 acid dew point analyzer chishandiso chakakosha chinogona kuyera iyo acid dova point tembiricha muflue gasi remaboilers uye mavira ekudziya online munguva chaiyo. Iyo acid dova point tembiricha yakayerwa nechiridzwa inogona kunyatso kudzora tembiricha yekupisa gasi yemaboilers uye mavira ekudziya, kuderedza tembiricha yakaderera sulfuric acid dova point corrosion, kunatsiridza kushanda kwemafuta, kuwedzera bhailer inoshanda kuchengetedza uye kuwedzera hupenyu hwemidziyo.
Mushure mekushandisa Nernst 1735 asidhi dova pfungwa analyzer, unogona zvakarurama kuziva asidhi dova pfungwa ukoshi ari flue gasi boilers uye kudziyisa mavira, uyewo okisijeni kugutsikana, mvura mhute (% mvura mhute ukoshi) kana dova pfungwa ukoshi uye mvura zvirimo ( G magiramu/KG pakirogiramu) uye humidity kukosha RH. Mushandisi anogona kudzora tembiricha yekupedza gasi mukati meimwe nhanho yakakwira zvishoma pane acid dova poindi yeflue gasi zvichienderana nekuratidzwa kwechiridzwa kana maviri 4-20mA masaini ekubuda, kuitira kudzivirira yakaderera-tembiricha asidi corrosion uye kuwedzera kuchengeteka kwekushanda kwebhailer.
Mumaindasitiri boilers kana magetsi ekudyara boilers, petroleum kunatsa uye makemikari mabhizinesi uye kupisa mavira. Mafuta ezvicherwa (gasi, gasi rakaomarara, marasha, mafuta anorema, nezvimwewo) anowanzo shandiswa sehuturu.
Mafuta aya ane zvakawanda kana zvishoma zvesarufa, izvo zvinogadzira SO2mukupisa kweperoxide. Nekuda kwekuvapo kweokisijeni yakawandisa mukamuri yekupisa, huwandu hushoma hweSO2inowedzera kusanganiswa neokisijeni kuumba SO3, Fe2O3uye V2O5pasi pemamiriro emhepo akawandisa. (flue gasi uye inopisa simbi yepamusoro ine chikamu ichi).
Inenge 1 ~ 3% yezvose SO2inoshandurwa kuita SO3. SO3gasi mune yakakwira-tembiricha flue gasi haiparadze simbi, asi kana tembiricha yegesi inodonha pasi pe400 ° C, SO.3ichasangana nemhute yemvura kugadzira mhute ye sulfuric acid.
Iyo reaction formula ndeyotevera:
SO3+H2O ——— H2SO4
Kana sulfuric asidhi chiutsi chanyura pamusoro pekudziya kwepamusoro pamuswe wechoto, yakaderera-tembiricha sulfuric acid dova point corrosion ichaitika.
Panguva imwecheteyo, iyo sulfuric acid liquid yakanyungudutswa pane yakadzika-tembiricha yekudziya inonamatira kune guruva mugesi reflue kuita dota rinonamira risiri nyore kubvisa. Iyo flue gasi chiteshi yakavharwa kana kuvharika, uye kuramba kunowedzera, kuitira kuti uwedzere kushandiswa kwesimba kweiyo induced draft fan. Corrosion uye kuvharika kwedota kunoisa mungozi mamiriro ekushanda eiyo boiler yekudziya yepasi. Sezvo iyo flue gasi ine ese ari maviri SO3uye mhute yemvura, ivo vanogadzira H2SO4mhute, zvichikonzera kuwedzera kweasidhi dew point yeflue gasi. Kana tembiricha yegesi yeflue yakadzikira pane iyo acid dew point tembiricha yeflue gasi, H2SO4steam inonamatira kune flue uye yekupisa yekupisa kuumba H2SO4mhinduro. Kuwedzera kushatisa midziyo, zvichikonzera kupisa kunopisa kudonha uye kukuvara kweflue.
Mumidziyo inotsigira yechoto chekudziya kana bhaira, mashandisirwo emagetsi e flue uye kupisa anopisa anoverengera anenge makumi mashanu muzana ehuwandu hwesimba rekushandisa kwechishandiso. Iyo tembiricha yekupisa gasi inokanganisa kushanda kwekupisa kwekupisa kwehuni dzekudziya uye boilers. Iyo yakakwirira tembiricha yekuburitsa, inodzikira iyo thermal performance. Kune yega yega 10 ° C kuwedzera kwekushisa kwegasi rekubuda, kushanda kwemafuta kunodzikira neinenge 1%. Kana tembiricha yekubuda gasi yakadzikira pane tembiricha yedova remhepo yeflue gasi, inokonzeresa kuora kwemidziyo uye kukonzeresa njodzi dzekuchengetedza mukushanda kwekudziya kwevira uye boilers.
Iyo inonzwisisika tembiricha yekupisa yekupisa choto uye bhaira inofanira kunge yakakwira zvishoma pane iyo acid dew point tembiricha yeflue gasi. Naizvozvo, kuona iyo acid dew point tembiricha yekudziya kwevira uye boilers ndiyo kiyi yekuvandudza kushanda kwemafuta kunyatsoshanda uye kuderedza kushanda kwenjodzi.
