1 Toni gasi wowotchera nthunzi Chithunzi Chowonetsedwa

1 Ton gasi boiler yotentha

Kufotokozera Kwachidule:

Njira yopangira boiler ya gasi yoteteza chilengedwe
Ma boiler a gasi ochezeka ndi chilengedwe ali ndi zabwino zambiri pakugwiritsa ntchito.Zipangizozi zimatha kubwezanso utsiwo ndikuugwiritsanso ntchito, kuti kugwiritsa ntchito gasi kuchepe pang'ono.Ma boilers oteteza zachilengedwe adzakhazikitsa momveka bwino komanso mogwira mtima kabati yokhala ndi magawo awiri ndi zipinda zake ziwiri zoyaka moto, ngati malasha m'chipinda chapamwamba choyaka sichiwotchedwa bwino, amatha kupitiriza kuyaka ngati agwera m'chipinda choyaka moto.
Mpweya woyamba ndi mpweya wachiwiri udzakhazikitsidwa moyenerera komanso mogwira mtima muchitetezo cha gasi chotetezera chilengedwe, kuti mafuta athe kupeza mpweya wokwanira kuti azitha kuyaka, ndikuyeretsa ndi kuchitira fumbi labwino ndi sulfure dioxide.Pambuyo poyang'anitsitsa, zizindikiro zonse zakwaniritsidwa.Miyezo ya chilengedwe.
Ubwino wa ma boilers otenthetsera zachilengedwe ndi okhazikika panthawi yopanga.Zida zonse zimapangidwa ndi mbale zachitsulo zokhazikika.Zida zopangira ndi njira zopangira zidazo zimayesedwa molingana ndi zomwe zafotokozedwa.
Chowotchera chamafuta oteteza zachilengedwe ndi otetezeka kwambiri kuti chizigwira ntchito, kapangidwe kake kamakhala kokhazikika komanso kocheperako, zida zonse zimatenga malo ang'onoang'ono, ndipo kuthamanga kwa zidazo kumathamanga komanso kumagwira ntchito mokakamizidwa, komwe kumakhala kotetezeka komanso kokhazikika.Boiler yoteteza zachilengedwe imakhala ndi zida zingapo zotetezera chitetezo.Pamene kupanikizika kuli kwakukulu kuposa kupanikizika, valavu yotetezera idzatseguka kuti itulutse nthunzi kuti iwonetsetse ntchito yotetezeka.
Bokosi la ng'anjo yamoto wowotcha mpweya wowotchera zachilengedwe liyenera kuganizira za mawonekedwe amafuta omwe amagwiritsidwa ntchito popanga, ndipo zida zake ziyenera kugwiritsa ntchito mafuta omwe adapangidwa poyamba momwe angathere.mwina otsika.

Momwe mungasankhire chitoliro choyenera cha nthunzi

Vuto lofala pakali pano ndikusankha payipi yonyamulira nthunzi molingana ndi kukula kwa mawonekedwe a zida zolumikizidwa.Komabe, zinthu zofunika kwambiri monga kuthamanga kwa kutumiza ndi kutulutsa mpweya wabwino nthawi zambiri zimanyalanyazidwa.
Kusankhidwa kwa mapaipi a nthunzi kuyenera kudutsa muukadaulo komanso mawerengedwe azachuma.Zomwe Nobeth adakumana nazo zawonetsa kuti kusankha kolakwika kwa mapaipi a nthunzi kungayambitse mavuto ambiri.
Ngati kusankha kwa mapaipi ndi kwakukulu kwambiri, ndiye:
Mtengo wamapaipi ukuwonjezeka, kukulitsa kutchinjiriza kwa mapaipi, kukulitsa m'mimba mwake valavu, kuwonjezera thandizo la mapaipi, kukulitsa mphamvu, ndi zina zambiri.
Mtengo wowonjezera woyika komanso nthawi yomanga
Kuwonjezeka kwa mapangidwe a condensate
Kuwonjezeka kwa madzi opindika kumapangitsa kuchepa kwa nthunzi komanso kuchepa kwa kutentha kwabwino
· Kutaya kutentha kwambiri
Mwachitsanzo, kugwiritsa ntchito chitoliro cha nthunzi cha 50mm kumatha kunyamula nthunzi yokwanira, ngati mukugwiritsa ntchito chitoliro cha 80mm, mtengo wake udzakwera ndi 14%.Kutayika kwa kutentha kwa chitoliro cha 80mm ndi 11% kuposa chitoliro cha 50mm.Kutaya kwa kutentha kwa chitoliro cha 80mm chosakanizidwa ndi 50% kuposa chitoliro cha 50mm chosakanizidwa.
Ngati kusankha kwa mapaipi kuli kochepa kwambiri, ndiye:
·Nthunzi yothamanga kwambiri imapangitsa kuti mpweya ukhale wochepa kwambiri, ndipo pamene malo ogwiritsira ntchito nthunzi afika, kuthamanga sikukwanira, komwe kumafuna kuthamanga kwa boiler.

Nthunzi yosakwanira pamalo a nthunzi, chotenthetsera kutentha sichikhala ndi kusiyana kokwanira kwa kutentha kwa kutentha, ndipo kutentha kumachepa

· Kuthamanga kwa nthunzi kumawonjezeka, kosavuta kupanga scour ndi nyundo yamadzi

Mlingo wa chitoliro akhoza kusankhidwa ndi imodzi mwa njira ziwiri zotsatirazi.:
·Njira yothamanga
· Njira yotsitsa kuthamanga
Kaya ndi njira iti yomwe imagwiritsidwa ntchito popanga kukula, njira ina iyenera kugwiritsidwa ntchito kuyang'ana malingaliro amadzimadzi kuti zitsimikizire kuti malirewo sadutsa.
Kuyenda kwa chitoliro kumatengera kuyenda kwa chitoliro kukhala chofanana ndi gawo lapakati pa chitoliro ndi kutuluka kwake (kumbukirani kuti kuchuluka kwake kumasiyana ndi kukakamizidwa).
Ngati tidziwa kuthamanga kwa misa ndi kuthamanga kwa nthunzi, tikhoza kuwerengera mosavuta kuchuluka kwa voliyumu (m3 / s) ya chitoliro.Ngati titadziwa kuthamanga kovomerezeka (m / s) ndikudziwa kuchuluka kwa nthunzi yoperekedwa, titha kuwerengera gawo lofunikira lomwe limadutsa (m'mimba mwake wa chitoliro).
Ndipotu, kusankha payipi sikolondola, vuto ndi lalikulu kwambiri, ndipo vuto lamtunduwu nthawi zambiri silimakhala losavuta kupeza, choncho limayenera kulipidwa mokwanira.
