HRSG: injongo kunye neentlobo

HRSG yenzelwe ukusetyenziswa ekuvelisweni ubushushu leyo ihlawulwe yeegesi eziveliswa kumacandelo ahlukeneyo yokutsha iinjini mveliso kunye lwangaphakathi. izixhobo ezinjalo wayamene nayiphi lobushushu iziko ukunika kuphela ukusuka igesi zeemoto. Ezinye boilers ubushushu inkunkuma, senze njengenkqubo negesi ebandayo ngexesha ukuveliswa kwe-sulphuric acid.

Ngokuqhelekileyo, umphunga lisetyenziswa kushishino metallurgical inkunkuma-ubushushu kwibhoyila. It lobushushu igesi ifikelela +400 ° C, naxa usebenza amaziko intsimbi - +1500 ° C. Ukuba imveliso lweshishini ayikho phezulu kunjalo, izixhobo kakhulu ngempumelelo kunye nempompo kwegazi. Ngokuxhomekeke kuyilo layo, lo mphunga recovery kwibhoyila phantse ekhuselekileyo kokusingqongileyo, kususela ubuncinane ikhuphe izinto ezingcolisa. Ukongeza, yokuba ngokoqoqosho, kuba iindleko zokucoca igesi lisezantsi kakhulu, kwaye usebenzisa amafutha ngokufanelekileyo.

HRSG umphunga uqobo ifakelwe kwizityalo idizili kunye namandla negesi yendalo, microturbines, boilers idizili, njl Kushishino oyile carbon monoxide eveliswa ngexesha umsebenzi injini, warhawuka ukuveliswa kombane. Amanzi ngenxa iguqulelwa kwi ngomphunga ukhululeka ngaphandle. Le ndlela ukuzilungisa izenzo igesi kunye yokunyibilikisa isinyithi. Le umphunga amaxesha asetyenziswe iimfuno zobugcisa kumashishini apho kufuneka khona. Kwakhona kukho ukwehla kweendleko emanzini ashushu (ngokusebenzisa irisithi yayo kwibhoyila). Kwiintsalela output inkunkuma ngokusebenzisa ngetshimini.

Ulwakhiwo-utilizers boilers baye ezahlukeneyo. Ngaphandle imodeli ngasentla, kukho utyhalelwa imodeli kwegazi namaphephandaba zendalo. Kwakhona umahluko indlela leli igubu ngaphandle kwayo. Ezinye iinkampani nokuphuhlisa imizekelo-odolo ngamnye kuthathelwa ingqalelo nkcukacha ye indawo yokufaka (umzekelo, ngaphakathi okanye ngaphandle).

Kuxobekeka kwezo njongo, kukho kwakhona amanxuwa boilers ubushushu kunye umphunga ukuba izixhobo afterburning amazinga omnye, ababini okanye abathathu uxinzelelo efuna ezifuna tyaba okanye nkqo, kunye nabanye abaninzi. Kukho ezininzi iintlobo ubushushu inkunkuma, ngaphandle converters (for ahle kunye nesinyithi non-ayoni) , okanye izibonelelo ezisetyenzisiweyo (coke, iglasi, imfunxa isinyithi, intsimbi kunye nezinye izinto).

Nokuphawula umphunga HRSG yemodyuli, nto leyo kuthi kunxulunyaniswe ukufakelwa irhasi ulwelo lula kunezinye kwaye ayifuni iinkcitho ezinkulu. Isebenza ngokuthembeka xa ukuhla rhoqo umthwalo, kwakunye udluliselo elungileyo kakhulu ubushushu.

Ngaphambi kokufaka, kufuneka amisele uhlobo yintoni igunya liyadla omnye okanye omnye kwibhoyila recovery ubushushu. izixhobo umthamo eqhelekileyo ukususela 120 kW ukuya 1700 kW. Ukuza kuthi ga ngoku, kungakuhle ukubhekisela kwinkampani iingcali bamba kwibhoyila, ukuze ukuba bathi kwangaphambili apho modeli kungcono ukuyithenga. Ukuze inkonzo utilizers ezinikiweyo leri kunye namaqonga.
