I-CFB Insuratorngolunye uhlobo lokufuya imfucuza boler ngaphandle kwe-grate incinerator. Ukujikeleza kombhede okugcotshwa ngamanzi kube nezinzuzo eziningi, njengezinga eliphakeme kakhulu, okuqukethwe okuphansi kwekhabhoni kuhlu lokulungiswa komthwalo, ukulungiswa kwamafutha abanzi. Kodwa-ke, izindleko zayo zokusebenza ziphakeme kakhulu. Kubandakanya ukuphehla amandla okushisa okushisekela, ukususwa kanye nokususwa kothuli, i-DCS, ukuncishiswa kwemfucuza, ukondla kukaphethiloli nohlelo lokupholisa we-deslagging. Umkhiqizi we-MSW Incinerator uTaishan udonsela izifundo ezivela kubuchwepheshe obusezingeni eliphezulu be-CFB Solid Wastiniction Incuthol Technology e-European, futhi wethula i-MSW CFB Incurator enekhono lokwelashwa nsuku zonke lama-1000tons.
Inqubo yokuhlekisa yophethiloli eqinile
Ngemuva kokomiswa nokuhlunga, udoti oyinhloko awusekho imfucuza ngomqondo wendabuko, kepha uphethiloli wokubuyisa okuqinile. Ukuhlekisa ikakhulukazi kubandakanya ukomisa (ukunciphisa umswakama kusuka kuma-60% kuya ngaphansi kwama-30%), ukuchoboza imishini nokuhlunga. Yehlisa usayizi kadoti, susa izinto ezingavuthanga njengensimbi, imfucumfucu nengilazi, futhi wandise ingxenye yezinto ezivuthayo. Ukuhlekisa kuqinisekisa ukondla kaphethiloli, ukuhlanganiswa okuphelele, i-slag engaphansi kanye nesizukulwane se-dioxin, nokuphuma okuningi okuhlanzayo. Izici zikaphethiloli ngemuva kokuhlungwa kokomiswa nokusebenza kwemishini kukhonjiswa etafuleni 1.
Ithebula 1. Izici zikaphethiloli

Icubungula izici ze-CFB Insurator
. Iphinde yamukele ubuchwepheshe obuphindayo be-Flue Uhlelo oluzenzakalelayo lwe-Multi-Point Oudting lungaqinisekisa ezenzakalelayo eziphakemeyo nokudla okufanayo, futhi okuqukethwe kwe-fly ash kungafinyelela ku-5%.
(2) usayizi wezinhlayiyana kaphethiloli ongaphansi kwe-80mm wenza ukufutheka okwenele ngokwengeziwe. Ukuhlushwa kokungcoliswa kokungcola kuphansi, okuhambisana nokukhiqizwa okuhlanzekile futhi kuthuthukisa umnotho oyindilinga.
(3) Ngemuva kokuhlunga, ivolumu yodoti inciphisa ngo-40%, okwenza ukuthi i-slag icule.
(4) Ukushisa okuphezulu okuphezulu kanye ne-Sub-High Pressure Steam kuyazuzisa ukuguqulwa okusebenzayo kanye nokusetshenziswa kwamandla.
. Ukushisa kwe-Main Combustion Zone kungaphezulu kwama-900 ℃, izinga lokushisa legesi elingenamikhawulo lingaphezulu kwama-850 ℃, futhi isikhathi sokuhlala sidlula ama-2s. Ukulahleka kwe-Clinker Doction kungaphansi kwe-1.5% futhi ukuphuma kungcono kune-GB 18485-2014 I-Flue Emission Standard.
