Mubvunzo: Chii chinonzi dhiramu yemhepo inoputika?

A:

1. Steam dhiramu yejenareta

Iyo dhiramu yehutsi ndiyo inonyanya kukosha mumidziyo yemagetsi jenareta. Icho chinongedzo chiri pakati pematatu maitiro ekudziya, vaporization uye superheating yemhepo jenareta, uye inoita basa rekubatanidza.

Iyo dhiramu yemvura mwero weiyo steam chigubhu boiler chiratidzo chakakosha zvakanyanya panguva yekushanda kwebhailer. Chete kana iyo nhanho yemvura yakachengetedzwa mukati meyakajairwa huwandu hunogona kutenderera kwakanaka uye evaporation yebhailer kuve nechokwadi. Kana chiyero chemvura chakanyanya kuderera panguva yekushanda, ichaita kuti bhaira ive shoma nemvura. Yakanyanya boiler kushomeka kwemvura kuchaita kuti mvura madziro chubhu madziro kupisa, uye kunyange kukonzera kukuvara kwemidziyo.

Kana iyo nhanho yemvura yakakwira zvakanyanya panguva yekushanda kweboiler, dhiramu rehutsi rinozadzwa nemvura, izvo zvinozoita kuti tembiricha yehutsi idonhe nekukurumidza. Muzviitiko zvakakomba, mvura inounzwa muturbine nemhepo, zvichikonzera kukanganisa kwakakomba uye kukuvadzwa kwemashizha eturbine.

Naizvozvo, iyo yakajairwa dhiramu nhanho yemvura inofanirwa kuve nechokwadi panguva yekushanda kweboiler. Kuti ive nechokwadi cheyakajairika dhiramu yemvura mwero, boiler michina inowanzo shongedzerwa yakakwira uye yakaderera dhiramu mvura yekudzivirira uye nhanho yemvura inogadzirisa masisitimu. Iyo dhiramu yemvura level inowanzo patsanurwa kuva yakakwirira yekutanga kukosha, yakakwirira yechipiri kukosha uye yakakwirira yechitatu kukosha. Low drum water level yakakamurwa kuva yakaderera yekutanga kukosha, yakaderera yechipiri kukosha uye yakaderera yechitatu kukosha.

2. Munguva yenguva dzose yekushanda kwebhailer, chii chinodiwa pachiyero chemvura yedhiramu?

Iyo zero point yedhiramu yemvura level yeyakakwira-pressure dhiramu boiler inowanzoiswa pa50 mm pazasi pegeometric yepakati mutsara wedhiramu. Kutemerwa kweyero yemvura yakajairika yedhiramu remhepo, ndiko kuti, zero yemvura level, inotarwa nezvinhu zviviri. Kuti uvandudze hunyoro hwehutsi, nzvimbo yehutsi hwedhiramu inofanirwa kuwedzerwa zvakanyanya sezvinobvira kuchengetedza mwero wemvura wakaderera.

Zvisinei, kuitira kuti uve nechokwadi chekuchengetedzwa kwekutenderera kwemvura uye kudzivirira kubuda uye kupindira kwemhepo pamusuwo wepombi, mvura yakajairika inofanira kuchengetwa yakakwirira sezvinobvira. Kazhinji, mwero wemvura wakajairika unoiswa pakati pe50 ne200 mm pazasi pedhiramu repakati mutsara. Uye zvakare, iwo akakodzera epamusoro neakadzika mazinga emvura kune yega yega boiler anofanirwa kutariswa zvichibva payeyero yekuyerwa kwemvura yekuyerwa kwemvura-yakatonhodzwa madziro epombi yekudzika uye kutarisisa uye kuyerwa mhedzisiro yemhando yehuputi hwemvura. Pakati pavo, muganho wepamusoro wemvura inotarwa nekuti kunaka kwemhute yemvura kunoderera; muganho wakaderera wemvura wemvura unofanirwa kutariswa nekuti chiitiko chekubuda uye kupinza mutsinga kunoitika pamusuwo wepipepipe.
