Thaum tshav kub kub dissipation tej yam kev mob ntawm cua hluav taws xob cua sov

Lub tshuab rhaub hluav taws xob yuav tsum raug muab tso rau thiab kho kom raug. Qhov chaw cua kub zoo yuav tsum tau muab tso rau hauv cov kua lossis cov khoom hlau. Kev kub hnyiab yog txwv nruj heev. Thaum scale lossis carbon deposits pom nyob rau saum npoo ntawm cov yeeb nkab, lawv yuav tsum tau muab ntxuav thiab rov qab siv raws sij hawm kom tsis txhob txo kev siv lub sij hawm vim cua kub dissipation. Thaum tshav kub kub fusible hlau los yog khoom saltpeter, alkali, leaching, paraffin, thiab lwm yam. Qhov ua hauj lwm voltage ntawm lub rhaub hluav taws xob yuav tsum tau qis dua ua ntej, thiab cov ntsuas hluav taws xob yuav tsum tsis txhob nce ua ntej qhov nruab nrab melts. Thaum cua sov cua sov, cov khoom yuav tsum tau muab sib npaug rau hauv tus qauv ntoo khaub lig kom muab cov cua sov kom zoo thiab ua kom cua sov tag nrho.

Thaum cua sov saltpeter nrog lub tshuab hluav taws xob, kev ntsuas kev nyab xeeb yuav tsum tau coj los tiv thaiv kev sib tsoo tawg. Cov hlua hluav taws xob yuav tsum tau muab tso rau sab nraum lub rwb thaiv tsev txheej kom tsis txhob muaj kev sib cuag nrog cov khoom siv hluav taws xob corrosive, explosive media, thiab ya raws. Cov hlau lead yuav tsum muaj peev xwm tiv taus qhov kub thiab txias ntawm cov khoom siv hluav taws xob rau lub sijhawm ntev. Thaum zawm cov hlua txuas, yuav tsum tsis txhob muaj zog ntau dhau. Cov khoom ntawm lub tshuab hluav taws xob yuav tsum tau muab cia rau hauv qhov chaw qhuav. Yog tias qhov rwb thaiv tsev tsis zoo nyob hauv qab 1 lub sijhawm ntev ω, Nws tuaj yeem qhuav hauv qhov cub ntawm ib ncig ntawm 200 degree lossis cua sov los ntawm kev txo qhov hluav taws xob kom txog thaum cov rwb thaiv tsev rov qab los. Magnesium oxide hmoov ntawm lub qhov hluav taws xob ntawm lub qhov hluav taws xob cua sov lub raj yuav tsis nkag mus los ntawm cov pa phem thiab ya raws los ntawm qhov chaw siv, tiv thaiv kev sib tsoo.

Txoj kev khiav hauj lwm thiab cov hauv paus ntsiab lus ntawm kev tiv thaiv cua sov hauv hluav taws xob cua sov

Cov txheej txheem ntawm kev siv lub tshuab hluav taws xob kom sov ib yam khoom yog yooj yim heev. Nws siv cov nyhuv Joule uas tsim los ntawm tam sim no los hloov hluav taws xob zoo rau hauv thermal zog kom sov cov khoom. Txoj kev cua sov no tseem tuaj yeem muab faib ua ob hom: cov cua sov ncaj qha thiab cov cua sov ncaj qha, nrog rau cov kev cai sib txawv.

Yog tias cov cua sov ncaj qha siv rau lub tshuab hluav taws xob, lub zog hluav taws xob tuaj yeem siv ncaj qha rau cov khoom cua sov. Thaum cov dej ntws tam sim no tas sij hawm, cov khoom rhuab nws tus kheej tuaj yeem tsim kom sov. Los ntawm qhov kev xav no, cov khoom uas tuaj yeem raug cua sov ncaj qha los ntawm kev tiv thaiv yuav tsum yog cov conductors thiab muaj hluav taws xob ntau dua. Vim lub fact tias cov cua sov yog generated los ntawm cov khoom rhuab nws tus kheej, thermal efficiency yog khi rau siab.

Kev tiv thaiv hluav taws xob ncaj qha ntawm cov cua sov hluav taws xob xav tau cov cua sov ua los ntawm cov khoom siv tshwj xeeb alloy lossis cov khoom tsis yog xim hlau, uas tom qab ntawd tsim lub zog thermal thiab xa mus rau cov khoom siv hluav taws xob los ntawm hluav taws xob, convection, thiab conduction txoj kev.

Rau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv cua sov tau muab faib ua ob ntu, yog li qhov ntau ntawm cov khoom siv cua sov feem ntau tsis txwv thiab kev ua haujlwm yooj yim. Nws tsuas yog tsim nyog kom muaj kev xav tau siab rau cov khoom siv hauv cov khoom cua sov. Nyob rau hauv ib txwm muaj xwm txheej, nws yuav tsum tau txaus siab rau cov kev cai xws li siab resistivity, tsis tshua muaj kub coefficient tsis kam, me deformation ntawm kub kub, thiab tsis yooj yim embrittlement.

Cov ntaub ntawv hlau xws li hlau aluminium alloy, npib tsib xee chromium alloy, los yog cov ntaub ntawv tsis yog xim hlau xws li silicon carbide thiab molybdenum disilicide feem ntau yog siv los ua cov khoom siv cua sov hauv lub tshuab hluav taws xob, thiab qhov kub thiab txias ntawm cov khoom siv kuj sib txawv.
