Kweziphi iinkalo apho ukongiwa kwamandla ejenereyitha yomphunga werhasi kubonakaliswe kweziphi? Zeziphi ezinye iindlela zokunciphisa ilahleko yobushushu?
Okwangoku, iinkampani ezininzi ziye zasebenzisa izixhobo zejenereyitha yegesi entsha ekuphunyezweni nasekuphuhliseni inkqubo. Ukuvela kunye nokusetyenziswa kwesi sixhobo kuncede kakhulu imveliso yethu kunye nemveliso. Ngokusisiseko, ukonga amandla anxulumeneyo wejenereyitha yomphunga wegesi yamkelwe. Yeyiphi imiba ephambili yokonga amandla kwiijenereyitha zomphunga?
Ukonga amandla ejenereyitha yomphunga werhasi
1. Ngethuba lokuphunyezwa kwejenereyitha yegesi yegesi, i-fuel kunye nomoya zixutywe ngokupheleleyo: umlinganiselo omhle wokutsha kunye ne-fuel efanelekileyo kunye nezixhobo ezifanelekileyo zomoya awukwazi nje ukuphucula ukusebenza kakuhle kwe-fuel, kodwa nokunciphisa ukukhutshwa kweegesi ezingcolileyo. . Ukufezekisa injongo yokonga amandla ngeendlela ezimbini.
2. Ubushushu bombhobho okhutshwe kwijenereyitha ye-steam buhlaziywa kwakhona: ngokutshintshiselana kobushushu, ukushisa kwi-sewage eqhubekayo kusetyenziselwa ukunyusa izinga lokushisa lokunikezelwa kwamanzi angenayo i-deoxygenated, ngaloo ndlela kufezekiswa injongo yokugcina amandla ye-gas generator.
3. Ngokwenani le-steam efunekayo kwimveliso yemizi-mveliso, ngokwesayensi nangengqiqo khetha amandla alinganisiweyo wejeneretha ye-steam kunye nenani leejeneretha ze-steam. Ukuphakama komdlalo phakathi kwezi meko zimbini kunye nemeko ethile, incinci ilahleko yokukhupha umsi kunye nokucaca ngakumbi ukonga amandla.
4. Ukunciphisa ubushushu bokukhutshwa kwejenereyitha yomphunga wegesi: Nciphisa ubushushu bokukhutshwa kwejenereyitha yomphunga. Ukusebenza kweejenereyitha eziqhelekileyo zomphunga yi-85-88%, kwaye ukushisa kwegesi yokukhupha yi-220-230 ° C. Ukuba i-economizer isetyenzisiwe, ngoncedo lobushushu benkunkuma, ukushisa kokushisa kuya kuhla ukuya kwi-140-150 ° C, kwaye ukusebenza kakuhle kwejeneretha ye-steam kunokunyuswa ukuya kwi-90-93%.
Indlela yokunciphisa okanye ukuphepha ukulahlekelwa kobushushu bejenereyitha yomphunga werhasi ukufezekisa iziphumo zokonga amandla kunye nokuqinisekisa ukuba injini nganye yokutsha yangaphakathi ayinakho ukutsha kweoksijini?
Kweziphi iinkalo apho ukongiwa kwamandla ejenereyitha yomphunga werhasi kubonakaliswe kweziphi?
1. Inokunciphisa ukulahleka kobushushu: gcina iintsimbi zentsimbi yeejenereyitha zegesi.
2. Unokunciphisa ukukhupha ukulahleka kobushushu: lawula ngokufanelekileyo i-coefficient yomoya; jonga ngokukhawuleza ukuba umbane uyavuza; ukunciphisa ukusetyenziswa komoya obandayo ngexesha lokusebenza kwenkqubo yokusebenza; ucocekile ngexesha elifanelekileyo kunye ne-decoke, kwaye ugcine nayiphi na indawo yokufudumeza, ngakumbi ukufudumeza komoya Coca indawo yokufudumeza isixhobo kwaye unciphise ubushushu berhasi yokukhupha. Ukunikezelwa komoya kunye nokungena komoya kufuneka kuzame ukusebenzisa umoya oshushu phezulu kwejenereyitha yomphunga wegesi okanye umoya oshushu eludongeni lwesikhumba sendawo yokufudumeza yangasemva.
3. Ukunciphisa ilahleko yobushushu bokutsha kweekhemikhali ezingaphelelanga: ngokukodwa ukuqinisekisa ukuba i-coefficient yomoya engaphezulu efanelekileyo, ukuqinisekisa ukuba injini nganye yokutsha yangaphakathi ayinayo i-oksijini, kunye nokuqinisekisa ukuba i-fuel kunye nomoya zixutywe ngokupheleleyo kumaqondo okushisa aphezulu.
4. Inokunciphisa ilahleko yobushushu bokutshiswa okungaphelelanga kwezixhobo zoomatshini: i-coefficient yomoya eyongezelelweyo efanelekileyo kufuneka ilawulwe ukuze kuqinisekiswe ukuba i-fineness of pulverized coal ifanelekile; umthamo kunye nobude begumbi lokutsha zifanelekile, ubume kunye nokusebenza kuzinzile, uyilo lufanelekile, kunye nesantya sokuqala somoya kunye nesantya somoya wesibini zilungelelaniswe ngokufanelekileyo. Isantya somoya, ngokufanelekileyo ukwandisa isantya somoya wesibini ukwandisa ukutsha. Intsimi ye-aerodynamic kwijenereyitha yomphunga wegesi isebenza ngokuzinzileyo, kwaye ilangatye lingazalisa i-gas generator.
