Ukugcinwa kweGeneretha Yenjini Yegesi Yemvelo

Namuhla i-Dingbo Power yabelana ngezindlela zokunakekela zejeneretha yenjini yegesi yemvelo, ngethemba ukuthi iwusizo kuwe.

Izindleko zokuyilungisa ziyahlukahluka ngohlobo, isivinini, ubukhulu kanye nenani lamasilinda enjini.Lezi zindleko ngokuvamile zihlanganisa:

• Umsebenzi wokunakekela

• Izingxenye zenjini nezinto ezisetshenziswayo njengezihlungi zikawoyela, izihlungi zomoya, ama-spark plug, ama-gaskets, amavalvu, ama-piston ring, izakhi zikagesi, njll. nezinto ezisetshenziswayo ezifana nowoyela.

• Ukulungiswa okuncane nokukhulu.

Ukunakekela kungenziwa izisebenzi zasendlini noma kwenziwe inkontileka kubakhiqizi, abasabalalisi, noma abathengisi abangaphansi kwezinkontileka zesevisi.Izinkontileka zokulungisa ngokugcwele (ezihlanganisa yonke isevisi enconyiwe) ngokuvamile zibiza phakathi kuka-1 kuya ku-2.5 cents/kWh kuye ngosayizi wenjini, isivinini kanye nesevisi.Izinkontileka eziningi zesevisi manje zifaka ukuqapha okukude kokusebenza kwenjini nezimo ngaphezu kokuvumela ukulungiswa okubikezelwayo.Izilinganiso zenkontileka yesevisi ngokuvamile zibandakanya konke, okuhlanganisa isikhathi sokuhamba sochwepheshe kumakholi wesevisi.

Isevisi enconyiwe ihlanganisa ukuhlolwa/ukulungiswa kwesikhashana esifushane okuvamile nokushintshwa ngezikhathi ezithile kukawoyela wenjini nezihlungi, okokupholisa, namapulaki ezinhlansi (imvamisa amahora angama-500 kuye kwayizi-2,000).Ukuhlaziywa kukawoyela kuyingxenye yezinhlelo eziningi zokuvikela ukunakekela ukuqapha ukuguga kwenjini.Ukulungiswa kwe-top-end ngokuvamile kunconywa phakathi kwamahora angu-8,000 nangu-30,000 okusebenza (bona Ithebula 2-5) okuhlanganisa nekhanda lesilinda kanye nokwakhiwa kabusha kwe-turbocharger.Ukulungiswa okukhulu kwenziwa ngemva kwamahora angu-30,000 kuya kwangu-72,000 okusebenza futhi kuhilela ukushintshwa kwepiston/liner, ukuhlolwa kwe-crankshaft, ama-bearings, nama-seal.Izikhathi zokunakekela zikhonjiswe kuThebula 2-5.

Izindleko zokunakekela ezethulwe kuThebula 2-6 zisekelwe esilinganisweni somkhiqizi wenjini ngezinkontileka zesevisi ezihlanganisa ukuhlolwa okujwayelekile kanye nokulungiswa okuhleliwe kwesethi yokuphehla injini.Izindleko zisekelwe emahoreni okusebenza onyaka ayizi-8,000 avezwa ngokuphehlwa kukagesi ngonyaka.Ukugcinwa kwenjini kungahlukaniswa kube izingxenye ezigxilile ezidinga ukwenziwa ngokuphindaphindiwe kungakhathaliseki isikhathi sokusebenza kwenjini kanye nezingxenye eziguquguqukayo ezincike emahoreni okusebenza.Abathengisi bacaphune zonke izindleko ze-O&M ngokushintshashintsha kwesistimu ekusebenzeni kokulayisha okuyisisekelo.

2.4.7 Amafutha

Ngokungeziwe ekusebenzeni kwegesi yemvelo, izinjini zokuthungela izinhlansi zisebenza kwezinye izinhlobo zezinto ezibaswayo zegesi okuhlanganisa:

• I-liquefied petroleum gas (LPG) – ingxube ye-propane ne-butane

• Igesi emuncu – igesi yemvelo engacutshungulwanga njengoba iphuma ngqo emthonjeni wegesi.

• I-Biogas – noma imaphi amagesi avuthayo akhiqizwa ekulimaleni kwemfucuza yezinto eziphilayo, njengegesi yokulahla indle, igesi yokugaya indle, kanye negesi yokugaya imfucuza yezilwane.

• Amagesi emfucuza yezimboni - amagesi avuthayo futhi acubungule amagesi aphuma ezindaweni zokuhluza, izitshalo zamakhemikhali nezigayo zensimbi

• Amagesi akhiqiziwe - ngokuvamile igesi ye-Btu ephansi nephakathi ekhiqizwa njengemikhiqizo ye-gasification noma inqubo ye-pyrolysis Izinto ezinomthelela ekusebenzeni kwenjini yokuthungela inhlansi engenye yezinto ezibasela igesi zihlanganisa:

• Inani lokushisisa levolumu - Njengoba uphethiloli wenjini ulethwa ngokwevolumu, umthamo wamafutha enjini uyakhuphuka njengoba inani lokushisisa lincipha, okudinga ukwehla kwenjini kumafutha ane-Btu ephansi.Ukunciphisa kugqama kakhulu ngezinjini ezishibhile ngokwemvelo, futhi kuye ngezidingo zomoya, ukushaja kwe-turbo kunxephezela kancane noma ngokuphelele.

• Izimpawu zokuzenzakalela kanye nokuthambekela kokuqhunyiswa kwezibaseli ezinezilinganiso eziphansi ze-octane njenge-propane - Lokhu kuvame ukubonakala ngenani elibaliwe elaziwa ngokuthi i-Methane

Inombolo (MN).Okuhlukile abakhiqizi be-generator yegesi ingase ibale Inombolo yeMethane ngokuhlukile.Amagesi anezingxenye ze-hydrocarbon esindayo (i-Propane, i-Ethane, i-Butane, njll.) aneNombolo ye-Methane ephansi njengoba ezovame ukuzikhanyisela kalula.

• Izinto ezingcolile ezingase zibe nomthelela empilweni yengxenye yenjini noma ekugcinweni kwenjini, noma kuphumele ekukhishweni okungcolisa komoya okudinga izinyathelo zokulawula ezengeziwe.

• Amafutha aqukethe i-hydrogen angase adinge izinyathelo ezikhethekile (ngokuvamile uma okuqukethwe kwe-hydrogen ngevolumu kungaphezu kwamaphesenti angu-5) ngenxa yokuvutha okuyingqayizivele kwe-hydrogen nezici zokuqhuma.

Ithebula 2-7 liveza izingxenye ezimele ezinye zezibaseli zegesi uma kuqhathaniswa negesi yemvelo.Imfucuza yezimboni namagesi akhiqiziwe awafakiwe kuthebula ngoba ukwakheka kwawo kuyahluka kakhulu kuye ngomthombo wawo.Ngokuvamile aqukethe amazinga abalulekile we-H2 kanye/noma i-CO. Ezinye izakhi ezivamile i-CO2, umhwamuko, i-hydrocarbon eyodwa noma amaningi alula, kanye ne-H2S noma i-SO2.

Ukungcola kuwukukhathazeka ngezinto ezibaswayo eziningi, ikakhulukazi izingxenye zegesi ye-asidi (i-H2S, i-halogen acid, i-HCN; i-ammonia; usawoti nezinhlanganisela ezinensimbi; i-organic halogen-, sulphur-, nitrogen-, ne-silicon-containing compounds njenge-siloxanes);namafutha.Ekushiseni, izinhlanganisela ze-halogen nesibabule zakha ama-halogen acid, i-SO2, amanye ama-SO3 kanye nokuphuma okungenzeka kwe-H2SO4.Ama-asidi angakwazi futhi ukugqwala imishini engaphansi komfula.Ingxenye enkulu yanoma iyiphi i-nitrogen yamafutha ifakwa ku-NOx lapho kusha.Ukuze uvimbele ukugqwala nokuguguleka kwezingxenye, izinhlayiya eziqinile kufanele zigcinwe zisezingeni eliphansi kakhulu.Ukukhuhla uphethiloli okuhlukahlukene, ukuhlukaniswa kwamaconsi kanye nezinyathelo zokuhlunga kuyodingeka uma noma yimaphi amazinga okungcolisa uphethiloli edlula izicaciso zabakhiqizi.I-Landfill gas ikakhulukazi ivame ukuqukatha i-chlorine compounds, i-sulphur compounds, i-organic acid, kanye ne-silicon compounds, elawula ukwelashwa kusengaphambili.

Uma isilashiwe futhi yamukeleka ukuthi isetshenziswe enjinini, amaphrofayili okusebenza kokukhipha isisi kwamanye amafutha afana nokusebenza kwenjini yegesi yemvelo.Ikakhulukazi, izilinganiso eziphansi ezikhishwayo zezinjini ezishile ngokuvamile zingagcinwa kwezinye izinto zokubasa.
