Kukonzekera kwa Jenereta ya Injini Ya Gasi Yachilengedwe

Masiku ano Dingbo Power imagawana njira zosamalira za jenereta ya injini ya gasi, ndikuyembekeza kuti ndizothandiza kwa inu.

Ndalama zosamalira zimasiyana malinga ndi mtundu, liwiro, kukula ndi kuchuluka kwa masilindala a injini.Mitengo imeneyi nthawi zambiri imakhala:

• Ntchito yosamalira

• Zigawo za injini ndi zipangizo monga zosefera mafuta, zosefera mpweya, spark plugs, gaskets, mavavu, mphete za pisitoni, zida zamagetsi, etc. ndi zogwiritsira ntchito monga mafuta.

• Kukonzanso kwakung'ono ndi kwakukulu.

Kukonza kutha kuchitidwa ndi ogwira ntchito m'nyumba kapena kuperekedwa kwa opanga, ogulitsa, kapena ogulitsa pansi pa mgwirizano wantchito.Mapangano okonza zinthu zonse (okhudza ntchito zonse zovomerezeka) nthawi zambiri amawononga pakati pa 1 mpaka 2.5 cents/kWh kutengera kukula kwa injini, liwiro ndi ntchito.Makontrakitala ambiri a ntchito tsopano akuphatikiza kuyang'anira patali momwe injini ikugwirira ntchito ndi momwe zinthu zilili komanso kulola kukonzanso molosera.Mitengo ya makontrakitala a ntchito nthawi zambiri imaphatikizapo zonse, kuphatikizapo nthawi yoyendera ya akatswiri pama foni.

Ntchito zovomerezeka zimakhala ndi kuyezetsa kwakanthawi kochepa / kusintha komanso kusintha mafuta a injini pafupipafupi ndi zosefera, zoziziritsa kukhosi, ndi ma spark plugs (nthawi zambiri maola 500 mpaka 2,000).Kusanthula kwamafuta ndi gawo limodzi mwamapulogalamu ambiri oteteza kuwunika kwa injini.Kukonzanso komaliza kumalimbikitsidwa pakati pa maola 8,000 ndi 30,000 (onani Table 2-5) zomwe zimaphatikizapo mutu wa silinda ndi turbocharger kumanganso.Kukonzanso kwakukulu kumachitika pambuyo pa maola 30,000 mpaka 72,000 akugwira ntchito ndipo kumaphatikizapo kusintha pisitoni/liner, kuyendera crankshaft, mayendedwe, ndi zisindikizo.Nthawi zosamalira zikuwonetsedwa mu Table 2-5.

Ndalama zokonzetsera zomwe zaperekedwa mu Table 2-6 zimatengera kuyerekeza kwa opanga injini pamakontrakitala a ntchito zomwe zimaphatikizapo kuwunika kwanthawi zonse komanso kukonzanso kwadongosolo kwa seti ya jenereta.Mitengo imachokera pa maola 8,000 ogwira ntchito apachaka omwe amafotokozedwa malinga ndi kupanga magetsi pachaka.Kukonzekera kwa injini kungagawidwe m'zigawo zokhazikika zomwe ziyenera kuchitidwa mobwerezabwereza mosasamala kanthu za nthawi yoyendetsa injini ndi zigawo zosiyana zomwe zimadalira maola ogwira ntchito.Ogulitsawo adatchula ndalama zonse za O&M mosiyanasiyana pamachitidwe oyambira.

2.4.7 Mafuta

Kuphatikiza pakugwiritsa ntchito gasi wachilengedwe, injini zoyatsira moto zimagwiritsa ntchito mitundu ingapo yamafuta monga:

• Liquefied petroleum gas (LPG) - propane ndi butane mix

• Mpweya wowawasa - gasi wachilengedwe wosakonzedwa monga momwe amachokera ku chitsime cha gasi.

• Biogas - mpweya uliwonse woyaka wopangidwa kuchokera ku kuwonongeka kwachilengedwe kwa zinyalala, monga gasi wotayira kutayira, gasi wa digester digester, ndi mpweya wotayira zinyalala za nyama.

• Mipweya yotayira m'mafakitale - mipweya yoyaka moto ndikuchotsa mipweya kuchokera m'mafakitale, mafakitale opanga mankhwala ndi mphero.

• Mipweya yopangidwa - yomwe imakhala yotsika komanso yapakati-gasi wa Btu wopangidwa ngati zinthu zopangira gasification kapena pyrolysis Zinthu zomwe zimakhudza magwiridwe antchito a injini yoyaka moto yokhala ndi mafuta ena a gasi ndi monga:

• Mtengo wotentha wa Volumetric - Popeza kuti mafuta a injini amaperekedwa pang'onopang'ono, kuchuluka kwa mafuta mu injini kumawonjezeka pamene kutentha kumachepa, zomwe zimafuna kutsika kwa injini pamafuta omwe ali ndi Btu yochepa.Derating imawonekera kwambiri ndi injini zofunidwa mwachilengedwe, ndipo kutengera kufunikira kwa mpweya, turbocharging pang'ono kapena kwathunthu.

• Mawonekedwe odzidzidzimutsa okha ndi chizolowezi chophulika kwamafuta okhala ndi octane otsika ngati propane - Izi nthawi zambiri zimadziwika ndi mtengo wowerengeka wotchedwa Methane.

Nambala (MN).Zosiyana opanga ma jenereta a gasi Mutha kuwerengera Nambala ya Methane mosiyana.Mipweya yokhala ndi zigawo zolemera za hydrocarbon (Propane, Ethane, Butane, etc.) imakhala ndi Nambala yotsika ya Methane chifukwa imakonda kudziwotcha mosavuta.

• Zowononga zomwe zingasokoneze moyo wa injini kapena kukonza kwa injini, kapena kubweretsa mpweya woipa womwe umafunika njira zina zowongolera.

• Mafuta okhala ndi haidrojeni angafunike miyeso yapadera (nthawi zambiri ngati mpweya wa haidrojeni ndi wokulirapo kuposa 5 peresenti) chifukwa cha kuthekera kwapadera kwa hydrogen ndi kuphulika kwake.

Gulu 2-7 likuwonetsa zigawo zina zamafuta ena a gasi poyerekeza ndi gasi.Zinyalala zamafakitale ndi mpweya wopangidwa sizinaphatikizidwe patebulo chifukwa zolemba zake zimasiyana mosiyanasiyana kutengera komwe akuchokera.Nthawi zambiri amakhala ndi milingo ya H2 ndi/kapena CO. Zina zodziwika bwino ndi CO2, nthunzi wamadzi, ma hydrocarbon owala amodzi kapena angapo, ndi H2S kapena SO2.

Zowonongeka zimadetsa nkhawa ndi mafuta ambiri otayika, makamaka zigawo za gasi wa asidi (H2S, halogen acid, HCN; ammonia; mchere ndi zitsulo zokhala ndi zitsulo; organic halogen-, sulfure-, nitrogen-, ndi silicon-containing compounds monga siloxanes);ndi mafuta.Pa kuyaka, mankhwala a halogen ndi sulfure amapanga ma halogen acid, SO2, ena SO3 ndipo mwina amatulutsa mpweya wa H2SO4.Ma acidwa amathanso kuwononga zida zapansi pamtsinje.Kachigawo kakang'ono ka mafuta aliwonse a nayitrogeni amathiridwa mu NOx akayaka.Pofuna kupewa dzimbiri ndi kukokoloka kwa zigawo zikuluzikulu, tinthu tating'ono ting'onoting'ono timayenera kusungidwa kuti zisawonongeke kwambiri.Kupaka mafuta kosiyanasiyana, kulekanitsa madontho ndi kusefera kudzafunika ngati mafuta aliwonse oyipa apitilira zomwe opanga amapanga.Mpweya wotayira m'nthaka makamaka nthawi zambiri umakhala ndi mankhwala a chlorine, mankhwala a sulfure, ma organic acid, ndi ma silicon, omwe amalamula kuti asamasamalidwe.

Akagwiritsidwa ntchito ndikuvomerezedwa kuti agwiritsidwe ntchito mu injini, mawonekedwe amtundu wamafuta pamafuta ena amafanana ndi momwe injini ya gasi imagwirira ntchito.Mwachindunji, kuchuluka kwa mpweya wochepa wa injini zoyaka moto nthawi zambiri kumatha kusungidwa pamafuta ena.
