Integrated kupisa kupisa musimboti mukati muffle choto

Mukutsinhana kwekupisa kwechoto chemuffle, chinowanzo kupatsanurwa kuita angangoita matatu akasiyana tembiricha nzvimbo: choto gasi, madziro evira uye simbi inopisa. Pakati pavo, tembiricha Z yegasi revira yakakwira; kutonhora kwemadziro evira ndeyechipiri; tembiricha yesimbi inopisa Z yakaderera. Nenzira iyi, pakati pechoto nemadziro evira, pakati pechoto gasi nesimbi, uye pakati pechoto rusvingo nesimbi, kupisa kunoitwa nenzira yemwaranzi uye convection, uye kunewo kurasikirwa kwekupisa nekuda kwe kupisa kwekupisa kwemadziro evira (iyo Kurasikirwa kwekupisa kunewo imwe pesvedzero pakutsinhana kwekupisa muchoto).

1. Radiation kupisa kupisa kwechoto gasi kune simbi Mushure mokunge kupisa kunopisa nechoto chemoto kunotamirwa kumadziro echoto uye pamusoro pesimbi, chikamu chayo chinokwezva uye chimwe chikamu chinoratidzwa kumashure. Kupisa kunoratidzwa kunofanira kupfuura nepakati pegasi revira rinozadza choto, chikamu chayo chinotorwa negasi rechoto, uye chikamu chakasara chinovhenekera kune chakatarisana nemadziro evira kana simbi, uye inovhenekerwa kakawanda.

2. Convective heat transfer yechoto gasi kusvika kusimbi Muchoto chiripo chevira remoto, tembiricha yegasi rechoto inonyanya kuenzana 800 ℃ ~ 1400 ℃. Kana tembiricha yegasi rechoto yakatenderedza 800 ° C, mhedzisiro yemwaranzi uye convection inenge yakaenzana. Kana tembiricha yegasi rechoto yakakwira kupfuura 800 ° C, iyo convective kupisa kutamisa kunodzikira, nepo mhepo inopisa yekupisa inowedzera zvakanyanya. Semuenzaniso, kana tembiricha yegasi remuchoto wakavhurika muchigayo chesimbi inosvika 1800 ° C, chikamu chinopenya chasvika 95% yehuwandu hwekupisa kupisa.

3. Mhepo yekupisa kwemwaranzi yemadziro echoto uye denga revira kune simbi yakafanana neyakapfuura, uye zvakare inodzokororwa inoenderera nemwaranzi. Musiyano ndewekuti mukati memadziro echoto chinotorawo kupisa nenzira ye convective, uye kupisa uku kuchiri kufambiswa nenzira inopenya.

Chete apo kupisa kwemukati kwemoto wemufuremu kwave yunifomu kunogona kushandiswa kweiyo muffle furnace kuve nani. Mushure mekuverenga zviri pamusoro apa, iwe unofanirwa kunzwisisa iyo yakasanganiswa kupisa kupisa maitiro mukati memuffle choto.
