Downpipe nrog steam:
Nyob rau hauv ib txwm ua haujlwm ntawm lub tshuab hluav taws xob, chav tsis tuaj yeem muaj nyob rau hauv lub downcomer, txwv tsis pub, cov dej yuav tsum tau ntws mus rau hauv qab thiab cov chav yuav tsum tau ntab mus rau pem hauv ntej, thiab ob qho tib si tawm tsam ib leeg, uas tsis tsuas yog txhim kho cov dej ntws, tab sis kuj tseem txo cov kev khiav dej num, thaum qhov teeb meem loj heev, huab cua tsis kam yuav tsim, uas yuav ua rau cov dej ntws mus nres, ua rau cov dej tsis txaus thiab kev puas tsuaj rau cov kav dej-txias phab ntsa.Yuav kom daws tau qhov teeb meem no, lub downcomer ntawm lub tshuab hluav taws xob yuav tsum tsis txhob raug tshav kub, thiab yuav tsum tau txuas nrog cov dej qhov chaw ntawm lub nruas, kom deb li deb tau nyob rau hauv qab ntawm lub nruas, thiab xyuas kom meej tias qhov siab ntawm lub nruas. inlet ntawm downcomer thiab cov dej qis ntawm lub nruas tsis qis Plaub zaug ntawm txoj kab uas hla ntawm downcomer.Txhawm rau tiv thaiv kom tsis txhob muaj cov pa tawm mus rau hauv cov yeeb nkab.
Loop daig:
Thaum siv lub tshuab hluav taws xob, nyob rau hauv tib lub voj voog, thaum txhua lub raj ascending nyob rau hauv parallel yog rhuab unevenly, qhov ceev ntawm chav-dej sib tov nyob rau hauv lub raj uas tsis muaj zog rhuab yuav tsum ntau dua li ntawm chav dej sib tov. nyob rau hauv lub raj uas muaj zog rhuab.Raws li qhov kev pom zoo tias cov dej xa dej ntawm cov kav dej qis qis qis, qhov ntws ntawm cov yeeb nkab nrog cov cua sov tsis muaj zog tuaj yeem poob, thiab tej zaum yuav nyob rau hauv lub xeev ntawm stagnation.Qhov xwm txheej no yog hu ua stagnation, thiab lub sijhawm no, cov pa hauv cov yeeb nkab riser tsis tuaj yeem nqa mus rau lub sijhawm., ua rau cov yeeb nkab phab ntsa overheating yeeb nkab rupture xwm txheej.
Soda txheej:
Thaum cov kav dej-txias phab ntsa ntawm lub tshuab hluav taws xob tau teeb tsa kab rov tav lossis kab rov tav, thiab qhov ntws ntawm cov dej sib xyaw hauv cov raj tsis siab dhau lawm, vim tias chav dej sib dua ntau dua li dej, chav dej ntws saum cov hlab. , thiab cov dej ntws hauv qab cov raj.Qhov xwm txheej no yog hu ua Soda-dej stratification, vim qhov tsis zoo thermal conductivity ntawm chav, sab saum toj ntawm cov yeeb nkab yog yooj yim overheated thiab puas.Yog li ntawd, lub riser los yog qhov hluav taws xob yeeb nkab ntawm cov dej qab zib-dej sib tov tsis tuaj yeem teem rau kab rov tav, thiab qhov inclination yuav tsum tsis pub tsawg dua 15 degrees.
Loopback:
Thaum cov cua sov ntawm txhua lub raj ascending nyob rau hauv parallel yog heev uneven, lub chav dej sib tov nyob rau hauv lub raj nrog lub zog tshav kub raug yuav muaj ib tug muaj zog lifting quab yuam, tus txaus tus nqi yuav loj heev thiab ib tug suction nyhuv yuav tsim, ua rau lub chav. - dej sib tov nyob rau hauv lub raj uas tsis muaj zog tshav kub raug ntws mus rau hauv ib qho kev taw qhia txawv ntawm cov kev taw qhia ntawm ib txwm ncig, qhov teeb meem no yog hu ua rov qab ncig.Yog hais tias qhov nce ceev ntawm cov npuas yog tib yam li cov dej ntws nrawm nrawm, nws yuav ua rau cov npuas ua rau stagnate thiab tsim "air resistance", uas yuav ua rau cov yeeb nkab overheated ntawm cov yeeb nkab cua tsis kam mus rau rupture.
