Integrated tshav kub hloov txoj cai nyob rau hauv lub muffle rauv

Hauv kev sib pauv cua sov ntawm lub qhov cub muffle, nws feem ntau muab faib ua yam tsawg kawg peb qhov sib txawv ntawm qhov kub thiab txias: qhov cub hluav taws xob, cov phab ntsa rauv thiab cov hlau rhuab. Ntawm lawv, qhov kub thiab txias Z ntawm lub cub tawg yog siab; qhov kub ntawm lub cub tawg yog qhov thib ob; Qhov kub ntawm cov rhuab hlau Z yog qhov tsawg. Nyob rau hauv txoj kev no, nruab nrab ntawm lub cub tawg thiab lub cub tawg phab ntsa, nruab nrab ntawm lub cub tawg thiab cov hlau, thiab nruab nrab ntawm lub cub tawg phab ntsa thiab cov hlau, kev sib hloov cua sov yog nqa tawm nyob rau hauv daim ntawv ntawm hluav taws xob thiab convection, thiab kuj muaj cua sov poob vim hais tias ntawm lub cub tawg. thermal conduction ntawm lub cub tawg phab ntsa (Qhov kub poob kuj muaj qee yam cuam tshuam rau kev sib pauv cua sov hauv qhov cub).

1. Cov hluav taws xob hluav taws xob hloov hluav taws xob ntawm cov roj hluav taws xob rau cov hlau Tom qab cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob tau xa mus rau cov phab ntsa ntawm lub cub tawg thiab cov nplaim ntawm cov hlau, ib feem ntawm nws yog attracted thiab lwm qhov yog reflected rov qab. Cov hluav taws xob uas muaj hluav taws xob yuav tsum dhau los ntawm cov roj hluav taws xob uas ua rau lub cub tawg, ib feem ntawm cov roj hluav taws xob tau nqus los ntawm lub tshuab hluav taws xob, thiab qhov seem ntawm qhov hluav taws xob yog hluav taws xob mus rau qhov hluav taws xob hluav taws xob sab nraud lossis cov hlau, thiab nws yog radiated ntau zaus.

2. Convective cua sov hloov ntawm lub cub tawg rau hlau Nyob rau hauv lub cub tawg uas twb muaj lawm ntawm nplaim taws, qhov kub ntawm lub cub tawg yog feem ntau nyob rau hauv qhov ntau ntawm 800 ℃ ~ 1400 ℃. Thaum lub cub tawg kub nyob ib ncig ntawm 800 ° C, qhov cuam tshuam ntawm hluav taws xob thiab convection yuav luag sib npaug. Thaum lub cub tawg kub siab tshaj 800 ° C, lub convective tshav kub hloov tau txo, thaum lub radiative tshav kub hloov mus nce sharply. Piv txwv li, thaum qhov kub ntawm qhov qhib-hearth rauv roj nyob rau hauv ib lub zeb zeb mus txog 1800 ° C, qhov radiant tau mus txog li 95% ntawm tag nrho cov tshav kub hloov.

3. Cov hluav taws xob hluav taws xob hloov hluav taws xob ntawm cov phab ntsa ntawm lub qhov cub thiab lub ru tsev rau cov hlau zoo ib yam li yav dhau los, thiab nws kuj tseem rov ua hluav taws xob tas li. Qhov txawv yog tias sab hauv ntawm lub qhov cub phab ntsa kuj absorbs cua sov nyob rau hauv ib tug convective yam, thiab cov cua sov no tseem kis tau nyob rau hauv ib tug radiant yam.

Tsuas yog thaum lub tshav kub hloov mus rau hauv lub qhov cub muffle yog qhov sib xws tuaj yeem siv cov nyhuv ntawm lub qhov cub muffle zoo dua. Tom qab nyeem cov ntsiab lus saum toj no, koj yuav tsum nkag siab txog kev sib xyaw ua ke ntawm cov cua sov hloov mus rau hauv lub qhov cub muffle.
