Q: Yuav ua li cas paub qhov txawv ntawm cov chav khov thiab cov pa hluav taws xob superheated?

A:

Tsuas yog muab tso, Chav Generator yog kev lag luam boiler uas ua kom dej ua kom sov rau qee yam los ua cov pa taws kub. Cov neeg siv tuaj yeem siv cov ncu rau kev tsim khoom lag luam lossis cua sov raws li xav tau.

Chav generators yog tus nqi qis thiab siv tau yooj yim. Tshwj Xeeb, Roj Chav Generators Thiab Cov Chav Electric Chav Generators Uas Siv Zog Huv Si Thiab Dawb Dawb.

Thaum cov kua dej yaj hauv qhov chaw muaj tsawg, cov kua molecules nkag rau qhov chaw saum toj no los ntawm cov kua saum cov kua thiab ua cov vapor molecules. Txij li thaum lub chav dej molecules yog nyob rau hauv chaceot thileal suab tau tsa suab, lawv sib tsoo nrog txhua lwm yam, lub thawv phab ntsa thiab cov kua ua kua. Thaum sib tsoo nrog cov kua ua kua, qee cov molecules tau nyiam los ntawm cov kua molecules thiab rov qab mus rau cov kua kom ua kua molecules. Cov. Thaum evaporation pib, tus naj npawb ntawm cov molecules nkag mus rau qhov chaw yog ntau dua tus naj npawb ntawm molecules rov qab mus rau cov kua. Raws li evaporation txuas ntxiv, qhov ceev ntawm vapor lwg me me nyob rau hauv qhov chaw txuas ntxiv nce, yog li cov molecules rov qab mus rau cov kua kuj nce ntxiv. Thaum tus naj npawb ntawm cov molecules nkag rau hauv qhov chaw ib lub sijhawm yog sib npaug zos rau cov molecules rov qab mus rau cov kua, evaporation thiab hws nyob hauv lub xeev ntawm kev sib npaug ntawm kev sib npaug. Nyob rau lub sijhawm no, txawm hais tias evaporation thiab hws tseem muaj kev sib tw, qhov ntom ntawm vapor lwg me me hauv qhov chaw tsis nce. Lub xeev nyob rau lub sijhawm no hu ua lub xeev surentation. Ua kua rau lub xeev uas muaj noo noo yog hu ua cov kua txob tau, thiab nws vapor yog hu ua cov chav khov (tseem hu ua chav khov).

Yog tias tus neeg siv xav kom ua tiav cov kev ntsuas ntsuas ntsuas thiab kev soj ntsuam ntau dua, nws raug pom zoo los kho nws li superheated ncu thiab them nyiaj rau qhov kub thiab kub. Txawm li cas los xij, xav txog cov teeb meem raug nqi, cov neeg siv khoom tuaj yeem them nyiaj rau qhov ntsuas kub nkaus xwb. Lub hom phiaj tshaj plaws rau lub xeev yog hais txog ib qho kev sib raug zoo ntawm qhov kub thiab txias ntawm qhov kub thiab txias ntawm qhov kub thiab txias. Yog tias ib tus ntawm lawv paub, lwm tus muaj nuj nqis tau tsau. Lub chav nrog txoj kev sib raug zoo no yog cov dej khov, txwv tsis pub nws tuaj yeem pom zoo li superheated steam rau kev ntsuas. Hauv kev coj ua, qhov ntsuas kub ntawm superheated chav tuaj yeem ua tau siab dua, thiab lub siab feem ntau yog cov chav khov (0.7mpa, 200 ° C chav yog zoo li no, thiab nws yog chav khov kho.

Txij li thaum chav tsim hluav taws xob chav yog lub zog hluav taws xob siv kom tau txais cov pa hluav taws xob zoo, nws muab cov thawv tsim los ntawm ob txheej txheem, uas yog cov pa hluav taws xob khov kho. Qee tus neeg tuaj yeem nug, dab tsi yog qhov sib txawv ntawm cov chav khov thiab cov pa hluav taws xob superheated hauv lub tshuab hluav taws xob chav hluav taws xob? Niaj hnub no, Naneth yuav tham nrog koj txog qhov sib txawv ntawm cov chav khov thiab chav tsev superheated.

1. Cov pa roj saturated thiab cov chav dej superheated muaj kev sib raug zoo sib txawv nrog kub thiab siab.
Cov chav khov yog chav tau txais ncaj qha los ntawm dej ua cua sov. Qhov kub, thiab ntom ntawm cov roj khov kho ib qho rau ib qho. Lub ntsuas kub nyob hauv qab tib lub siab cua siab yog 100 ° C. Yog tias muaj qhov kub tshaj tawm cov chav sov xav tau, tsuas yog ua kom lub zog ncu.
Superheated chav yog reheated ntawm lub hauv paus ntawm cov dej khov, uas yog, chav tsim tawm los ntawm cov cua sov uas tsis hloov pauv, tab sis nws qhov kub nce thiab nws lub volume nce.

2. Cov pa roj saturated thiab cov pa hluav taws xob superheated muaj cov kev siv sib txawv
Superheated stamp feem ntau yog siv nyob rau hauv thermal fais fab ntoo kom tsav chav turbines kom tsim hluav taws xob.
Cov chav khov yog feem ntau siv rau cov cuab yeej siv cua sov lossis cua sov.

3. Lub tshav kub sib pauv efficiency ntawm saturated chav thiab superheated chav sib txawv.
Lub tshav kub hloov efficiency ntawm superheated chav yog qis dua li ntawm cov chav khov.
Yog li ntawd, thaum lub sij hawm cov txheej txheem ntau lawm, lub chav ua haujlwm supeheated yuav tsum tau hloov mus rau hauv chav saturated dhau los ntawm kev siv kub thiab lub siab reducer rau rov siv dua.
Cov kev teeb tsa ntawm desuperheater thiab lub siab reducer feem ntau nyob rau sab xub ntiag ntawm chav siv thiab qhov kawg ntawm lub tog raj kheej. Nws tuaj yeem muab cov chav khov rau ib qho lossis ntau cov pa-siv cov khoom siv thiab txhim kho ntau dua.
