Nzira yekugadzirisa sei gasi steam jenareta tembiricha yakaderera?

Gasi steam jenareta inonziwo gasi steam boiler.Gasi steam jenareta chikamu chakakosha chemagetsi emagetsi.Power station boilers, steam turbines uye majenareta ndiwo mainjini makuru ezviteshi zvemagetsi emagetsi, saka magetsi echiteshi chemagetsi midziyo yakakosha yekugadzira nekugadzirisa simba remagetsi.Maindasitiri boilers akakosha midziyo yekugovera steam inodiwa pakugadzira, kugadzirisa uye kupisa mumabhizinesi akasiyana siyana.Kune akawanda maindasitiri boilers uye anoshandisa mafuta akawanda.Waste heat boilers anoshandisa yakakwirira-tembiricha yekupedza gasi senzvimbo yekupisa mukugadzira maitiro anoita basa rakakosha mukuchengetedza simba.

Kana hutsi huzhinji hunoshandiswa, pane zvinodiwa pakupisa kwemhepo.Kupisa kwepamusoro-tembiricha inoita basa rakakosha mumatanho akadai sekudziya, kuvirisa, uye sterilization.Tembiricha yeNobeth steam jenareta inogona kazhinji kusvika 171°C, asi dzimwe nguva vatengi vanotaura kuti tembiricha yehutsi yakadzikira uye haigone kuita zvinodiwa.Saka, chii chikonzero cherudzi urwu rwemamiriro ezvinhu?Tinofanira kuzvigadzirisa sei?Ngatikurukurei newe.

Chekutanga pane zvese, isu tinofanirwa kuona chikonzero nei tembiricha yemhepo yegasi generator isina kukwirira.Imhaka yekuti jenareta remhepo harina simba rakakwana, midziyo yakashata, kugadziridzwa kwekumanikidza hakuna musoro, kana tembiricha yemhepo inodiwa nemushandisi yakakwira zvakanyanya, uye jenareta imwechete haigone kuigutsa.

Aya anotevera akasiyana mhinduro anogona kugamuchirwa kune akasiyana mamiriro:
1. Simba risina kukwana rejenareta remhepo rinotungamirira zvakananga kukukundikana kwekubuda kwemhepo kuzadzisa zvinodiwa zvekugadzira.Huwandu hwehutsi hunobuda mujenareta rehutsi hahugone kusangana nehuwandu hwehutsi hunodiwa pakugadzirwa, uye tembiricha haina kukwana.
2. Pane zvikonzero zviviri zvekutadza kwemidziyo izvo zvinoita kuti tembiricha yehutsi inobuda mujenareta iderere.Imwe ndeyekuti geji yekumanikidza kana thermometer inotadza uye chaiyo-nguva tembiricha tembiricha uye kudzvanywa hakugone kunyatsotariswa;imwe yacho ndeyokuti chubhu yekudziya inopiswa kunze, huwandu hwemhepo inogadzirwa nejenareta inova diki, uye tembiricha haigone kusangana nezvinodiwa zvekugadzira.
3. Kazhinji kutaura, tembiricha uye kumanikidzwa kwesaturated steam zvinoenderana zvakananga.Kana iyo steam pressure ichiwedzerwa, tembiricha inokwirawo.Naizvozvo, kana iwe ukaona kuti tembiricha yemhepo inobuda mumhepo jenareta haina kukwirira, unogona kugadzirisa gauge yekumanikidza zvakakodzera.

Iyo tembiricha yehutsi haina kukwirira nekuti kana dzvinyiriro isina kukwira kupfuura 1 MPa, inogona kusvika kune zvishoma yakanaka kudzvanywa kwe 0.8 MPa.Chimiro chemukati chejenareta chemhepo chiri mumamiriro ekudzvinyirira kwakashata (kunyanya kuderera kudarika mhepo yemhepo, kazhinji yakakura kudarika 0).Kana dzvinyiriro yacho yakawedzera zvishoma ne 0.1 MPa, panofanira kuva nekugadzirisa kugadzirisa.Mune mamwe mazwi, kunyangwe iri yakaderera pane 0, shandisa Iri zvakare jenareta rehutsi mukati me30L, uye tembiricha ichakwira kupfuura 100 ° C.

Kumanikidzwa kwakakwirira kudarika 0. Kunyange zvazvo ndisingazivi kuti ukuru chii, kana yakakura kudarika mhepo yemhepo, inenge yakakwirira kudarika 100 degrees.Kana dzvinyiriro yakakwira kupfuura kudzvanywa kwemuchadenga, tembiricha yemafuta ekutamisa kupisa yakadzikira, kana coil evaporator inopiswa nekugezwa.Kazhinji kutaura, inzvimbo yemuviri yemhute yemvura.Ichaputika kana yasvika 100, uye mhepo haigoni kusvika nyore nyore tembiricha yakakwira.

Kana chiutsi chawedzera kumanikidza, chiutsi chinoona tembiricha yakakwira zvishoma, asi kana ikadzika pasi penguva dzose mhepo yemhepo, tembiricha inodonha pakarepo kusvika ku 100. Nzira chete yekuita chinhu chakadai pasina kusimudza-kusimudza injini yemhepo ndeyekutendeuka. the steam kupinda negative pressure.Nguva imwe neimwe iyo dzvinyiriro yemhepo inowedzera ne1, tembiricha yemhepo inokwira neanenge gumi, uye zvichingodaro, ingani tembiricha inodiwa uye kuti yakawanda sei kumanikidza kunoda kuwedzerwa.

Mukuwedzera, kana tembiricha yemhepo yakakwira kana kwete inonangwa.Kana nzira dziri pamusoro dzichiri kusakwanisa kugadzirisa dambudziko rekushomeka kwekushisa kwemuputi unobuda mujenareta, zvinogona kungove kuti tembiricha inodiwa yakanyanya uye yakapfuura kugona kwemidziyo.Muchiitiko ichi, Kana pasina zvakaomesesa zvinodiwa pakumanikidza, funga kuwedzera steam superheater.

Muchidimbu, zviri pamusoro zvese zvikonzero nei tembiricha yemhepo yejenareta isina kukwirira.Chete nekubvisa matambudziko anogona kuitika mumwe nemumwe tinogona kuwana nzira yekuwedzera tembiricha yemhepo inobuda mumhepo inoputika.
