Ukulungisa amazinga okushisa e-Steam generator, okokuqala kudingeka aqonde izici nezitayela ezithinta ukuguqulwa kwamazinga okushisa anukuthekile, futhi asiqondise kahle ukuze alungiswe ngempumelelo amazinga okushisa amunca ukuze amazinga okushisa amunca angalawulwa ngaphakathi kwebanga elifanele. Ngokuvamile, izici ezithinta ukuguqulwa kwezinga lokushisa le-Steam zingahlukaniswa izingxenye ezimbili, okungukuthi ithonya lohlangothi lwegesi olungenamdlandla kanye nohlangothi lweSteam ekushintsheni kwamazinga okushisa okushisa.
1. Ukuthonya izici ohlangothini lwegesi olungenalutho:
1) Ithonya lokuqina kokuqina. Lapho umthwalo uhlala ungashintshiwe, uma ukuhlanganiswa kuqinisiwe (ivolumu yomoya kanye nevolumu ebalulekile ye-coal), kanti izinga lokushisa eliyinhloko lizokhuphuka, futhi izinga lokushisa eliyinhloko lizonyuka ngenxa yokushisa kwentuthu kanye nevolumu yegesi ye-flue; Ngaphandle kwalokho, bazokwehla, futhi ingcindezi yentukula izonyuka. I-amplitude of Temperature Shintsha ihlobene ne-amplitude yokushintshwa kokuqina.
2) Ithonya lesikhundla se-Flame Center (Center Center). Lapho isikhungo selangabi somlilo siqhubekela phambili, i-runlet yokushisa i-Sweet yenyuka. Njengoba i-supertheater futhi i-rehouter ihlelwe engxenyeni engenhla yesithando somlilo, ukushisa okukhazimulayo kwamunca inyuka, kubangele amazinga okushisa aphambili anda. Kuboniswa ekusebenzeni kwangempela, lapho i-Coal Mill ishintshela ekusebenzeni okuphakathi nendawo okuphakathi nendawo, ukufudumala okuphezulu kwe-Steate kukhuphuka. Ngaphezu kwalokho, lapho uphawu lwamanzi luphansi kwe-generator ye-steam, ingcindezi engemihle esithandweni somlilo izoncela umoya obandayo ukusuka phansi kwesithando, okuvusa maphakathi nelangabi, okuzokwenza ukuthi izinga lokushisa eliphakeme livuselelekile likhuphuke kakhulu. Ezimweni ezinzima, izinga lokushisa le-Steam lizoshisa ngokweqile kwe-Wall lokushisa lidlula umkhawulo kuzo zonke izici.
3) Ithonya levolumu yomoya. IVomusi Yomoya ithinta ngqo ivolumu yegesi ye-Flue, okusho ukuthi inomthelela omkhulu kwi-convection Type Superheater kanye noReater. Emklamweni wethu we-generator generator, izici zokushisa ze-Steam of Supertheater zivame uhlobo lwe-convection, futhi izici zokushisa ze-Steam of the Rehiter zihlukile. Kunguhlobo lwe-convection, ngakho-ke njengoba ivolumu yomoya inyuka, izinga lokushisa le-Steam liyanda, futhi njengoba ivolumu yomoya incipha, izinga lokushisa le-Steam liyancipha.
2. Ithonya ohlangothini lweSteam:
1) Ithonya lomswakama we-Steated Steated kumazinga okushisa anu. Uma kukhula umswakama we-Steated Steated, okuqukethwe kwamanzi okuningi, kanye nokwehlisa izinga lokushisa le-Steam. Ukuswakama komswakama okugcwele kuhlobene nekhwalithi yamanzi e-soda, izinga lamanzi lesigubhu seSteam kanye nenani lokuhwamuka. Lapho ikhwalithi yamanzi e-boiler imbi futhi okuqukethwe usawoti kukhuphuka, kulula ukudala ukuhwamuka komusi namanzi, okubangela umusi ukuba ungene; Lapho izinga lamanzi esigudwini seSteam lihlala liphezulu kakhulu, indawo yokuhlukaniswa kwesihlukanisi se-cyclone ngaphakathi kwesigubhu iyancishiswa, futhi umphumela wokuhlukanisa weSteam namanzi ancishisiwe, okungenzeka ukuthi adambiswe, okungenzeka ukuthi kuncishiswe, okungenzeka ukuthi kuncishiswe, okungenzeka ukuthi kuncishiswe ukungenelwa komusi. Amanzi; Lapho ukuhwamuka kwama-boiler kungazumayo kukhuphuka noma kugcwele kakhulu, isilinganiso sokugeleza kwesiteleka sikhuphuka kanye nekhono le-Steam lokuthwala amaconsi amanzi likhuphuka, elizokwenza ukuthi ububanzi bukhuphuke, obuzokwenza ububanzi bamakhandlela bamanzi athwalwa ngomusi ogcwele kakhulu. Izimo ezingenhla zizodala ukwehla okungazelelwe kumazinga okushisa amusha, okuthi ngamacala amakhulu azosongela ukusebenza okuphephile kweTurbine Turbine. Ngakho-ke, zama ukukugwema ngesikhathi sokusebenza.
2) Ithonya lokucindezela okukhulu kwe-steam. Njengoba ingcindezi inyuka, amazinga okushisa akhuphuka, futhi ukushisa okudingekayo ukushintsha amanzi abe ngumuphu. Lapho inani likaphethiloli lihlala lingashintshiwe, umthamo wokuhwamuka kwe-boiler uncipha khona manjalo, okungukuthi, inani le-Steam elidlula endaweni eyisimangaliso elisezingeni eliphakeme, elibangela izinga lokushisa le-steam likhuphuke. Ngokuphambene nalokho, ingcindezi iyancipha futhi izinga lokushisa le-Steam liyancipha. Kodwa-ke, kufanele kuqashelwe ukuthi umthelela wokushintsha kwengcindezi kumazinga okushisa kuyinqubo yesikhashana. Njengoba ingcindezi iyancipha, ivolumu kaphethiloli nevolumu yomoya izokwanda. Ngakho-ke, izinga lokushisa elimunca lizogcina likhuphuke, noma lize lifinyelele ezingeni elikhulu (kuya ngokwanda kwevolumu kaphethiloli). degree). Lapho uqonda le ndatshana, khumbula ukuthi "qaphela imililo ecidayo lapho ingcindezi iphakeme (inani lamafutha lizoncishiswa kakhulu, futhi libangele ukugcwala ngokweqile lapho ingcindezi iphansi."
3) Ithonya lokushisa kwamanzi okuphakelayo. Njengoba izinga lokushisa lamanzi okuphakelayo likhuphuka, inani lamafutha adingekayo ukukhiqiza inani elifanayo le-Steam liyancipha, inani le-flue gesi elinciphayo kanye nezinga lokugeleza liyancipha, kanye nezinga lokushisa lomlilo lincipha. Sekukonke, isilinganiso sokufakwa kokushisa kwe-radiant superheater sakhuphuka, kanye nokulinganiselwa kokushisa kwento enobukhulu obukhulu kuncipha. Ngokwesici se-Supersheatshi yethu enobandlululo kanye nompesheni ophuthule, okuhlangenwe nakho okusemqoka nokuvuselela kabusha kwehla, futhi ivolumu yamanzi ehlekisayo iyancipha. Ngokuphambene nalokho, ukwehla kokushisa kwamanzi okuphakelayo kuzodala amazinga okushisa aphezulu abuke akhuphuke. Ekusebenzeni kwangempela, kusobala ikakhulukazi lapho wenza umsebenzi wokuncipha okuphezulu nokufaka. Khokha ukunakwa okwengeziwe futhi wenze izinguquko ezifika ngesikhathi.
