Kwimveliso yemizi-mveliso, abavelisi be-Steam basetyenziswa ngokubanzi kumacandelo anje ngamandla ukuveliswa, ukufudumeza nokulungisa. Nangona kunjalo, emva kokusetyenziswa kwexesha elide, inani elikhulu lokungcola kunye ne-sediment liza kuqokelela ngaphakathi komvelisi weSteam, oya kuchaphazela kakhulu ukusebenza kunye nobomi bezixhobo. Ke ngoko, ukukhutshwa kwe-loger rhoqo yindlela efanelekileyo ukugcina ukusebenza kwesiqhelo komphunga weSteam.
I-blowdown eqhelekileyo ibhekisa ekususweni kwesiqhelo kwe-dill kunye ne-sediment ngaphakathi komvelisi weSteam ukugcina ukusebenza ngokufanelekileyo kwezixhobo. Le nkqubo ihlala ibandakanya la manyathelo alandelayo: Okokuqala, vala ivalve ye-Inlet yeValve ye-Inlet kunye neHallote yeKhola yeSteam yokumisa ukuhanjiswa kwamanzi kunye nokuntywila; emva koko, vula ivalve yokuhamba yokukhupha ubumdaka kunye ne-sediment ngaphakathi komvelisi weSteam; Okokugqibela, vala ivalve ye-valve, iphinde ivule ivalve yase-Interve kunye neValve yokukhuphela, kwaye ibuyise ubonelelo lwamanzi kunye ne-drainage.
Kutheni le nto ivuthelwa rhoqo ngabavelisi be-Steam babaluleke kangaka? Okokuqala, ubumdaka kunye ne-sediment ngaphakathi komvelisi weSteam unokunciphisa ukudluliselwa kwempumelelo kobushushu bezixhobo. Olu daka luya kwenza ukungaxhathisi ubushushu, kuthintele ukuhanjiswa kobushushu, kubangele ukusebenza kwempumelelo komvelisi weSteam ukunciphisa, ngaloo ndlela ikhulisa ukusetyenziswa kwamandla. Okwesibini, ubumdaka kunye ne-sediment bunokubangela ukosulwa kunye nokunxiba, ukuchaphazela kwakhona ubomi bezixhobo. I-Sorisosion iya konakalisa izinto zentsimbi zomvelisi we-steam, kwaye ukunxiba kuya kunciphisa ukusebenza kokutywina kwezixhobo, ngaloo ndlela kunyusa iindleko zokulungiswa kunye neenxalenye ezinokulungiswa.
I-frequency yomthengisi weSteam ivutha kwakhona ifuna ingqalelo. Ngokubanzi, imvana evuthayo yokuvuthwe abavelisi be-Steam kufuneka zimisele ngokusekwe ekusetyenzisweni kwezixhobo kunye neemeko zomgangatho wamanzi. Ukuba umgangatho wamanzi uhlwempuzekile okanye izixhobo zisetyenziswa rhoqo, kuyacetyiswa ukwandisa isantya sokunyuka kwamanzi ukuqinisekisa ukusebenza kwesiqhelo kwezixhobo. Kwangelo xesha, kuyayimfuneko ukuphinda ujonge imeko yokusebenza kwe-veloritor ye-Steam Veerator kunye nezinye izixhobo ezinxulumene noko ukuqinisekisa inkqubela phambili egudileyo yenkqubo yokomoya.
UHubei ungenabuchwephesha be-thebel ye-thermal, owayesaziwa ngokuba yi-Wuhan Noby Anneth Office Technology Technolookho kwimveliso ye-Steam kunye neenkonzo zeprojekthi kubathengi. Ngokusekwe kwimigaqo emihlanu yokugcina amandla okusindisa amandla, ukhuseleko oluphezulu, ukhuseleko lwendalo esinemigangatho ephezulu, i-Aibnect Steam Steators, i-Aitromagnectic Steams, i-Aitromagnect Steams Steam, ngaphandle kwe-300 yeStem I-Pleverators, zilungele amashishini asibhozo aphambili anjengeendawo zeyeza, ishishini le-biochemical, ukulungiswa kwendlela, oomatshini bokupakisha, oomatshini bokupakisha, kunye nempahla yokunxiba. Iimveliso zithengisa kakuhle kwilizwe liphela nakwiindawo ezingaphezu kwama-60 phesheya.
