P: U ka khetholla joang pakeng tsa mouoane o tletseng mouoane le mouoane o chesang haholo?

A:

Ka mantsoe a bonolo feela, jenereithara ea mouoane ke boiler ea indasteri e futhumatsang metsi ho isa tekanyong e itseng ho hlahisa mouoane o phahameng oa mocheso.Basebedisi ba ka sebelisa mouoane bakeng sa tlhahiso ea indasteri kapa ho futhumatsa ha ho hlokahala.

Lijenereithara tsa mouoane li theko e tlase ebile li bonolo ho li sebelisa.Ka ho khetheha, lijenereithara tsa mouoane oa khase le lijenereithara tsa mouoane tsa motlakase tse sebelisang matla a hloekileng li hloekile ebile ha li na tšilafalo.

Ha mokelikeli o fetoha mouoane sebakeng se lekanyelitsoeng se koetsoeng, limolek'hule tsa mokelikeli li kena sebakeng se ka holimo ka holim'a mokelikeli ebe li fetoha limolek'hule tsa mouoane.Kaha limolek'hule tsa mouoane li le motsamaong o sa tsitsang oa mocheso, li thulana, lebota la setshelo le bokaholimo ba mokelikeli.Ha li thulana le metsi, limolek'hule tse ling li hoheloa ke limolek'hule tsa mokelikeli ebe li khutlela mokelikeli ho fetoha limolek'hule tsa mokelikeli..Ha moea o fetoha mouoane o qala, palo ea limolek'hule tse kenang sepakapakeng e feta palo ea limolek'hule tse khutlelang mokelikeling.Ha mouoane o ntse o tsoela pele, ho teteana ha limolek'hule tsa mouoane sebakeng ho tsoela pele ho eketseha, kahoo palo ea limolek'hule tse khutlelang mokelikeling le eona ea eketseha.Ha palo ea limolek'hule tse kenang sebakeng ka nako ea yuniti e lekana le palo ea limolek'hule tse khutlelang mokelikeli, mouoane le condensation li boemong ba tekano e matla.Nakong ena, le hoja mouoane le condensation li ntse li tsoela pele, ho teteana ha limolek'hule tsa mouoane sebakeng ha ho sa eketseha.Boemo ka nako ena bo bitsoa saturation state.Mokelikeli o boemong ba ho tlala o bitsoa metsi a tletseng, 'me mouoane oa oona o bitsoa mouoane o omileng (o boetse o bitsoa saturated steam).

Haeba mosebelisi a batla ho fumana metering e nepahetseng le ho e beha leihlo, ho kgothaletswa ho e nka e le mouoane o chesang haholo le ho lefella mocheso le khatello.Leha ho le joalo, ha ho nahanoa ka litaba tsa litšenyehelo, bareki ba ka boela ba lefella mocheso feela.Boemo bo loketseng ba mouoane bo bolela kamano e bapileng e le 'ngoe lipakeng tsa mocheso, khatello le boima ba mouoane.Haeba e 'ngoe ea tsona e tsejoa, litekanyetso tse ling tse peli lia tsitsa.Mouoane o nang le kamano ena o tletse mouoane, ho seng joalo o ka nkoa e le mouoane o chesang haholo bakeng sa ho lekanya.Ha e le hantle, mocheso oa mouoane o chesang haholo o ka ba holimo, 'me khatello ka kakaretso e batla e le tlaase (mouoane o tletseng ho feta), 0.7MPa, 200 ° C mouoane o tjena,' me o chesa haholo.

Kaha jenereithara ea mouoane ke sesebelisoa sa matla a mocheso se sebelisetsoang ho fumana mouoane oa boleng bo phahameng, se fana ka mouoane o hlahisoang ke mekhoa e 'meli, e leng mouoane o tletseng mocheso le mouoane o chesang haholo.Motho e mong a ka 'na a botsa, phapang ke efe pakeng tsa mouoane o tletseng mouoane le mouoane o chesang haholo ka jenereithara ea mouoane?Kajeno, Nobeth o tla bua le uena ka phapang pakeng tsa mouoane o chesang haholo le mouoane o chesang haholo.

1. Mouoane o futhumetseng le mouoane o chesang haholo o na le likamano tse fapaneng le mocheso le khatello.
Mouoane o phoroselang ke mouoane o fumanoang ka kotloloho ho tsoa ho futhumatsang metsi.Thempereichara, khatello, le ho teteana ha mouoane o nang le metsi a mangata li lumellana le 'ngoe.Thempereichara ea mouoane tlas'a khatello e tšoanang ea sepakapaka ke 100°C.Haeba mocheso o phahameng oa mouoane o hlokahala, eketsa feela khatello ea mouoane.
Mouoane o chesang haholo o futhumatsa motheong oa mouoane o tletseng, ke hore, mouoane o hlahisoang ke mocheso oa bobeli.Mouoane o chesang haholo o tletse khatello ea mouoane e lulang e sa fetohe, empa mocheso oa eona oa eketseha 'me molumo oa oona oa eketseha.

2. Mouoane o futhumetseng le mouoane o chesang haholo li na le ts'ebeliso e fapaneng
Mouoane o chesang haholo hangata o sebelisoa lifemeng tsa motlakase o futhumatsang ho khanna li-turbine tsa mouoane ho fehla motlakase.
Mouoane oa saturated hangata o sebelisoa ho futhumatsa thepa kapa ho fapanyetsana mocheso.

3. Ts'ebetso ea phapanyetsano ea mocheso ea mouoane o tletseng mouoane le mouoane o chesang haholo o fapane.
Matla a ho fetisa mocheso oa mouoane o chesang haholo o tlase ho feta oa mouoane o tletseng.
Ka hona, nakong ea ts'ebetso ea tlhahiso, mouoane o chesang haholo o hloka ho fetoloa mouoane o tletseng ka ho fokotsa mocheso le ho fokotsa khatello hore o sebelisoe hape.
Boemo ba ho kenya mocheso oa "desuperheater" le "pressure reducer" hangata bo qetellong ea lisebelisoa tse sebelisang mouoane le qetellong ea silinda.E ka fana ka mouoane o tletseng mouoane bakeng sa thepa e le 'ngoe kapa e mengata e sebelisang mouoane le ho ntlafatsa katleho ea tlhahiso.
