IShell kunye neTube yokuTshintsha ubushushu kwiziTyalo zoMbane
Lo mtshintshisi{0}uphezulu wokusebenza usebenzisa uyilo lotshintshiselwano lobushushu olune-Inconel 625 iityhubhu, idala i-compact,-phezulu{3}}inqwaba yendawo yendawo. Iityhubhu ezibhijelwe kwindawo esembindini ye mandrel zonyusa isiphithiphithi, kuphunyezwa ukuhanjiswa kobushushu obulingana no 2000{14}}3000 W/m²K. Ngedayamitha yeqokobhe eyi-0.3-1 imitha, ayiphathi kuphela ulwelo olunamandla njenge-asidi yesulfuric kwizityalo zepetrochemical kodwa ikwasebenza njengenxalenye ebalulekileyo kwizityalo zamandla. Kumaziko okuvelisa amandla, idlala indima ebalulekileyo ekufudumezeni amanzi ebhoyila kwangaphambili, kusetyenziswa ubushushu obumdaka obusuka kwiigesi zokukhupha ukunyusa ubushushu bamanzi phambi kokuba bungene kwibhoyila. Oku kuphucula kakhulu ukusebenza kakuhle kwe-thermal kumjikelo weplanti yamandla, ukunciphisa amafutha afunekayo ukuvelisa umphunga. Ngokufumana kwakhona ubushushu obunokonakala ngenye indlela, kunciphisa ukusetyenziswa kwamafutha nge-15% ukuya kuma-20%, nto leyo ethetha ukonga iindleko ezinkulu kunye nokukhutshwa kwekhabhoni esezantsi. Uyilo lunciphisa ukuhla koxinzelelo ngelixa uphucula ukusebenza kakuhle kwe-thermal, okwenza ukuba ifaneleke ngokugqibeleleyo kubushushu obuphezulu, iinkqubo zoxinzelelo oluphezulu oluqhelekileyo lwezityalo zamandla zanamhlanje.
Idizayinelwe ukusebenza kweplanti yamandla, eli qokobhe kunye netyhubhu yomtshintshisi wobushushu ibonakalisa iqokobhe elinzima lekhabhoni yentsimbi - kunye netyhubhu yentsimbi engatyiwa-. Idlala indima ebalulekileyo ekuxinaniseni umphunga, ivumela ukusebenza okuthembekileyo kunye negalelo kwimveliso yamandla ezinzileyo kumaziko amakhulu okuvelisa amandla -. Ngokuphatha ngokufanelekileyo iinkqubo zokudibanisa umphunga, ixhasa ukuqhubeka nokusebenza ngokufanelekileyo kwezityalo zamandla.
Iinkcukacha zeMveliso
Amacandelo angundoqo kunye neMathiriyeli
◆ Izinto ze-Shell: Enzima - umsebenzi we-carbon steel shell. Inika amandla omelele ukuze umelane noxinzelelo oluphezulu - kunye neemeko zobushushu obuphezulu - ngaphakathi kwezixhobo zombane.
◆ I-Tube Material: I-stainless - iityhubhu zetsimbi (Inconel 625). Ezi ityhubhu zinika umhlwa okugqwesileyo kunye nokumelana nobushushu, ziqinisekisa ukuhlala ixesha elide - kunye nokudluliselwa kobushushu okusebenzayo kwimekobume yokuvelisa amandla.
Iiparamitha zokuSebenza
◆ Umthamo wokuThuthukiswa koBubushushu: Ukwazi ukuphatha imithwalo yobushushu ukuya kuthi ga kwi-100,000 kW. Ngedayamitha yeqokobhe le 0.3 - 1 yemitha, inokulawula ngokufanelekileyo iimfuno zokutshintshiselana kobushushu kwiinkqubo zeplanti yamandla.
◆ Indima yesicelo: Isebenza njengeyona nto ibalulekileyo kwizixhobo zombane ukulungiselela ukufudumeza amanzi kwibhoyila. Isebenzisa ubushushu bomphunga obusuka kwiigesi zokukhupha ukunyusa ubushushu bamanzi ngaphambi kokuba ingene kwibhoyila, iphucula kakhulu ukusebenza kakuhle kwe-thermal kumjikelo weplanti yamandla.
Uyilo loLwakhiwo kunye nokusebenza ngokufanelekileyo
◆ Uyilo lokutshintsha ubushushu: Ithatha idizayini yokutshintshiselana kobushushu kunye ne-Inconel 625 iityhubhu, idala i-compact, ephezulu - yendawo - yendawo yendawo. Olu luyilo luvumela ukuhanjiswa kobushushu okusebenzayo phakathi komphunga kunye namanzi okutya.
◆ Iinzuzo Zokusebenza: Ngokufumana kwakhona ubushushu obunokonakala ngenye indlela, kunokunciphisa ukusetyenziswa kwamafutha nge-15% - 20%, okukhokelela ekongeni kweendleko ezinkulu kunye nokukhutshwa kwekhabhoni esezantsi. Uyilo kwakhona lunciphisa ukwehla koxinzelelo ngelixa uphucula ukusebenza kakuhle kwe-thermal, iyenza ifanele - ifanele ubushushu obuphezulu -, obuphezulu - iinkqubo zoxinzelelo eziqhelekileyo zezityalo zanamhlanje zamandla.
Iimeko zeSicelo
◆ Lilungu eliyimfuneko kumaziko amakhulu - okuvelisa umbane, ngakumbi kwimizi-mveliso yamandla obushushu bobushushu (zombini iifosili - zezibaso - ezisekwe kunye neminye imithombo enokubakho ye-thermal). Kwezi zibonelelo, inegalelo ekusebenzeni ngokufanelekileyo komjikelo wokuvelisa amandla ngokufudumeza amanzi esondlo kwibhoyila, ngaloo ndlela iphucula ukusebenza kakuhle kwezityalo xa iyonke kunye nokunciphisa impembelelo yokusingqongileyo ngokusetyenziswa okuphantsi kwamafutha kunye nokukhutshwa kwezinto ezikhutshwayo.
Izinto Eziluncedo Ezingundoqo
