Nheyo huru yekubvisa guruva mumuromo ndeyekuparadzanisa zvidimbu zveguruva kubva mumhepo kana utsi.
Kutanga, zvidimbu zveguruva zvinonyoroveswa nemvura kuti zviwedzere kukura kwezvikamu uye simba regiravhiti. Zvikamu zveguruva zvinobva zvaparadzana nemhepo kana gasi rinobuda mumhepo. Kana muromo wekubvisa sulfurization watyoka, tinofanira kubvisa muromo weguruva. Mashandiro chaiwo ndeekuti:
1) zvikamu zvinomira kana zvikamu zvinosara zvinofanirwa kuchengetwa nemazvo: Vatengesi vese vane marongero akakosha uye mazita, kureva kuti, zvinofanira kuiswa pasina kushandiswa. Manozzle anobvisa sulfuri anofanira kunyikwa mumafuta (peturu, mafuta edhiziri, nezvimwewo) kudzivirira ngura.
2) Kana paine dambudziko pamusoro pemuromo wekubvisa sulfurization uri kushandiswa, kuongororwa kwemuromo wemuromo kunofanirwa kupatsanurwa. Vashandisi vanofanirwa kushandisa maturusi akakosha kana maturusi akakodzera kupatsanura nekuparadza hukama hwemusangano nhanho nhanho.
3) Manotsi akabviswa anofanira kuiswa ipapo ipapo pabhenji rekuyera notsi panzvimbo pekurapa chero kupi zvako. Zvichienderana nekumanikidzwa kwakatarwa kwekushanda, hunhu hwekuyerera kwemvura, kuona kona yekupfapfaidza uye kutarisa kunaka kwepfapfaidza kunoitwa. Izvi zvinogona kugadziriswa pakugadzirisa matambudziko.
Mushonga wekubvisa sarufa wakabuda pasi pezvinodiwa zvekuchengetedza nharaunda. Chinangwa chikuru chechigadzirwa ndechekubvisa sarufa mugasi nezvimwewo. Izvi zvinoita kuti kugadzirwa kwemaindasitiri kuve kwakachengeteka nharaunda. Hunhu hwemakemikari hwemushonga wekubvisa sarufa hwatsanangurwa pazasi, uye tiri kutarisira kukubatsira.
Kuramba kwe oxidation kwema nozzles e desulphurization
Kana zvinhu zvesilicon carbide zvikapiswa kusvika 1300 degrees mumhepo, silicon dioxide protective layer inoumbwa pamusoro pesilicon carbide crystal. Kukora kweprotective layer kunodzivirira silicon carbide yemukati kuti isarambe ichioxidation. Izvi zvinoita kuti silicon carbide ive ne resistance yakanaka ye oxidation. Kana tembiricha iri pamusoro pe 1900K (1627 C), silica protective film inoparadzwa. Panguva ino, oxidation yesilicon carbide inowedzera. Saka, 1900K ndiyo tembiricha yepamusoro yekushanda yesilicon carbide mumhepo inooxidation.
Kudzivirira kweasidhi uye alkaline kwema nozzles ekubvisa sulphur:
Panyaya yekudzivirira acid, alkali resistance uye oxidation, basa resilicon dioxide protective film rinogona kuwedzera acid resistance uye alkali resistance yesilicon carbide.
