Q:Kodi kulephera kwa kayendedwe ka madzi kwa jenereta ya nthunzi ndi chiyani

A: Jenereta ya nthunzi nthawi zambiri imatenthetsa ndikutulutsa madzi mung'anjo kudzera pakuyaka kwamafuta kuti apereke moyo ndi kutenthetsa. Pazikhalidwe zodziwika bwino, kuyendayenda kwa madzi opingasa kumakhala kokhazikika, koma pamene kayendedwe ka kayendedwe kake kamakhala kosakhazikika kapena ntchitoyo ndi yosayenera, zolephera zina zimachitika nthawi zambiri.
Pansi pa nthunzi:
Pazikhalidwe zogwirira ntchito za jenereta ya nthunzi, nthunzi siingakhalepo mu downcomer, apo ayi, madzi ayenera kuyenderera pansi, ndipo nthunzi iyenera kuyandama mmwamba, ndipo ziwirizo zimatsutsana wina ndi mzake, zomwe sizimangowonjezera kukana, komanso zimachepetsa kuyendayenda, pamene zinthu zili zovuta, kukana kwa mpweya kudzapangidwa, zomwe zidzachititsa kuti madzi asamayendetsedwe, kuchititsa kuti madzi asamawonongeke. Kuti athetse vutoli, chotsitsa cha jenereta cha nthunzi sichiyenera kutenthedwa ndi kutentha, ndipo chiyenera kugwirizanitsidwa ndi malo a madzi a ng'oma, momwe zingathere kugwirizana ndi pansi pa ng'oma, ndikuonetsetsa kuti kutalika pakati pa cholowera cha downcomer ndi madzi otsika a ng'oma si otsika kanayi m'mimba mwake ya downcomer. Pofuna kupewa nthunzi kuti isalowe mu chitoliro.

Loop yakhazikika:
Panthawi yogwiritsira ntchito jenereta ya nthunzi, mofanana ndi kuzungulira, pamene chubu iliyonse yokwera mofanana imatenthedwa mosagwirizana, kachulukidwe ka kusakaniza kwa nthunzi-madzi mu chubu chomwe chimakhala chofooka chiyenera kukhala chachikulu kuposa chisakanizo cha nthunzi-madzi mu chubu chomwe chimatenthedwa kwambiri. Poganizira kuti madzi a m'mipopiyi ndi ochepa, kuthamanga kwa chitoliro chopanda mphamvu kungathe kutsika, ndipo kungakhale kopanda pake. Izi zimatchedwa cycle stagnation. Panthawiyi, nthunzi mu chitoliro chokwera sichingatengedwe nthawi. , kutsogolera ku chitoliro khoma kutenthedwa chitoliro anaphulika ngozi.
Soda layering:
Pamene madzi ozizira khoma machubu a jenereta nthunzi amakonzedwa mopingasa kapena yopingasa, ndipo kuthamanga kwa madzi osakaniza nthunzi mu machubu si mkulu kwambiri, popeza nthunzi imakhala yopepuka kwambiri kuposa madzi, nthunzi imayenda pamwamba pa machubu, ndipo madzi amayenda pansi pa machubu. Izi amatchedwa Soda-madzi stratification, chifukwa osauka matenthedwe madutsidwe nthunzi, pamwamba pa chitoliro mosavuta overheated ndi kuonongeka. Chifukwa chake, chitoliro chokwera kapena chotulutsira chamadzi osakaniza a soda sichingakonzedwe molunjika, ndipo kupendekera sikuyenera kukhala kosachepera 15 digiri.
Loopback:
Kutentha kwa chubu chilichonse chokwera mofananira kumakhala kosagwirizana kwambiri, kusakaniza kwamadzi ndi nthunzi mu chubu ndi kutentha kwamphamvu kumakhala ndi mphamvu yokweza kwambiri, kuthamanga kwake kumakhala kokulirapo kwambiri ndipo kuyamwa kumapangidwa, zomwe zimapangitsa kusakanikirana kwamadzi ndi nthunzi mu chubu ndi kutentha kofooka kuyenderera kunjira yosiyana ndi komwe kumayenda bwino, izi zimatchedwa reverse circulation. Ngati kukwera kothamanga kwa thovu kumakhala kofanana ndi kuthamanga kwamadzi otsika, kumapangitsa kuti thovu liziyenda bwino ndikupanga "kukana mpweya", zomwe zingayambitse kuphulika kwa chitoliro chotenthedwa mu gawo la chitoliro cha mpweya.
