Ukugcinwa koMveliso weNjini yeGesi yeNdalo

Namhlanje i-Dingbo Power yabelana ngeendlela zokulondolozwa kwejenereyitha yegesi yendalo, ndiyathemba ukuba iluncedo kuwe.

Iindleko zokuyigcina ziyahluka ngokohlobo, isantya, ubukhulu kunye nenani leesilinda zenjini.Ezi ndleko ziquka:

• Umsebenzi wokulungisa

• Amalungu e-injini kunye nezinto ezifana nezihluzo zeoyile, izihluzi zomoya, iiplagi zentlantsi, iigaskets, iivalvu, iiringi zepiston, izinto zombane, njl. njl. kunye nezinto ezisetyenziswa njengeoyile.

• Uhlengahlengiso oluncinci nolukhulu.

Ugcino lunokwenziwa ngabasebenzi bangaphakathi okanye kuqeshwe ngemvumelwano kubavelisi, abasasazi, okanye abathengisi abaphantsi kwezivumelwano zenkonzo.Iikhontrakthi zokugcinwa ngokupheleleyo (ezibandakanya zonke iinkonzo ezicetyiswayo) zidla ngokuba phakathi kwe-1 ukuya kwi-2.5 yeesenti/kWh ngokuxhomekeke kubukhulu benjini, isantya kunye nenkonzo.Iikontraki ezininzi zenkonzo ngoku zibandakanya ukubeka esweni okude kokusebenza kweenjini kunye neemeko ngaphezu kokuvumela ukulungiswa kwangaphambili.Amaxabiso ekhontrakthi yenkonzo ngokuqhelekileyo aquka konke, kubandakanywa nexesha lokuhamba lamagcisa kwiifowuni zenkonzo.

Inkonzo ecetyiswayo ibandakanya uhlolo/uhlengahlengiso lwexesha elifutshane kunye nokutshintshwa kwamathuba athile kwe-oyile ye-injini kunye nezihluzo, into yokupholisa, kunye neeplagi zentlantsi (ngokuqhelekileyo iiyure ezingama-500 ukuya kuma-2,000).Uhlalutyo lwe-oyile luyinxalenye yeenkqubo ezininzi zothintelo lokulondoloza ukujonga ukuguga kweenjini.Uqwalaselo ngokutsha oluphezulu ngokuqhelekileyo luyacetyiswa phakathi kwe-8,000 kunye ne-30,000 yeeyure zokusebenza (jonga iTheyibhile 2-5) ebandakanya intloko ye-cylinder kunye ne-turbocharger kwakhona.Uhlengahlengiso olukhulu lwenziwa emva kweeyure ezingama-30,000 ukuya kwezingama-72,000 zokusebenza kwaye lubandakanya ukutshintshwa kwepiston/liner, ukuhlolwa kwecrankshaft, iibheringi, kunye nezitywino.Amaxesha olondolozo aboniswa kwiThebhile 2-5.

Iindleko zogcino ezichazwe kwiThebhile 2-6 zisekwe kuqikelelo lomenzi we-injini kwiikontraka zenkonzo ezibandakanya uhlolo lwesiqhelo kunye nohlengahlengiso olucwangcisiweyo lweseti yejenereyitha ye-injini.Iindleko zisekelwe kwiiyure zokusebenza zonyaka ezingama-8,000 ezichazwe ngokwemiqathango yokuveliswa kombane ngonyaka.Ukugcinwa kwe-injini kunokwahlulwa ibe ngamacandelo amiselweyo ekufuneka enziwe rhoqo kungakhathaliseki ukuba liliphi ixesha lokuqhuba injini kunye neenxalenye eziguquguqukayo ezixhomekeke kwiiyure zokusebenza.Abathengisi bacaphule zonke iindleko ze-O&M ngokwesiseko esiguquguqukayo senkqubo yokusebenza kwesiseko.

2.4.7 Izibaso

Ukongeza ekusebenzeni kwerhasi yendalo, iinjini zokutshisa intlantsi zisebenza kwiintlobo ngeentlobo zezibaso zegesi ezibandakanya:

• Irhasi yepetroleum engamanzi (LPG) – imixube yepropane kunye nebutane

• Irhasi emuncu – irhasi yendalo engalungiswanga njengoko iphuma ngqo kumthombo werhasi.

• I-Biogas – nayiphi na igesi enokutsha eveliswa ekuthotyweni kwezinto eziphilayo, ezifana nerhasi yokulahla inkunkuma, igesi yokucoca ugutyulo, kunye negesi yokugaya inkunkuma yezilwanyana.

• Iigesi zenkunkuma kwimizi-mveliso - iigesi ezivuthayo kunye nokucutshungulwa kweegesi ezivela kwiindawo zokucokisa, kwizityalo zekhemikhali kunye nelitye lokusila

• Iirhasi ezenziweyo – irhasi ye-Btu ephantsi nephakathi eveliswa njengemveliso yokwenziwa kwegesi okanye iinkqubo zepyrolysis Izinto ezichaphazela ukusebenza kwe-injini yomlilo wentlantsi ngezinye izibaso zegesi ziquka:

• Ixabiso lokufudumeza umthamo we-Volumetric - Ekubeni isibaso se-injini sihanjiswa ngokomthamo, umthamo wamafutha kwi-injini uyanyuka njengoko ixabiso lokufudumeza liyancipha, kufuna ukuthotywa kwe-injini kumafutha ane-Btu ephantsi.Ukunciphisa kucaca ngakumbi ngeenjini ezinqwenelekayo ngokwendalo, kwaye ngokuxhomekeke kwiimfuno zomoya, ukutshaja ngokuyinxenye okanye ngokupheleleyo kubuyekeza.

• Iimpawu zokuzitshisa kunye notyekelo lokuqhawuka kwamafutha ane-octane esezantsi yokulinganisa njengepropane - Oku kuhlala kuphawulwa ngexabiso elibaliweyo elaziwa ngokuba yiMethane.

Inani (MN).Eyahlukileyo abavelisi bejenereyitha yegesi inokubala inani leMethane ngokwahlukileyo.Iigesi ezinamacandelo e-hydrocarbon enzima (i-Propane, i-Ethane, i-Butane, njl.njl.) zineNani le-Methane elisezantsi njengoko ziya kuthanda ukuzenzela ngokulula ngakumbi.

• Izinto ezingcolisayo ezinokuchaphazela ubomi becandelo le-injini okanye ugcino lwe-injini, okanye zibangele izinto ezikhutshwayo ezingcolisa umoya ezifuna imilinganiselo eyongezelelweyo yolawulo.

• Amafutha aqulathe i-hydrogen anokufuna imilinganiselo ekhethekileyo (ngokukodwa ukuba umxholo we-hydrogen ngokomthamo ungaphezulu kwe-5 ekhulwini) ngenxa yokutsha okukodwa kwe-hydrogen kunye neempawu zokudubula.

Uluhlu 2-7 lubonisa amalungu amele amanye amafutha egesi xa kuthelekiswa nerhasi yendalo.Inkunkuma yamashishini kunye neegesi ezenziweyo azifakwanga kwitheyibhile kuba ukubunjwa kwazo kuyahluka ngokubanzi ngokuxhomekeke kwimvelaphi yazo.Ngokuqhelekileyo ziqulethe amanqanaba abalulekileyo e-H2 kunye / okanye i-CO. Ezinye iindawo eziqhelekileyo ziyi-CO2, umphunga wamanzi, i-hydrocarbons enye okanye ngaphezulu, kunye ne-H2S okanye i-SO2.

Ukungcola kuyinkxalabo ngamafutha amaninzi enkunkuma, ngokukodwa amacandelo e-asidi yegesi (i-H2S, i-halogen acids, i-HCN; i-ammonia; i-salts kunye ne-metal-containing compounds; i-organic halogen-, i-sulfur-, i-nitrogen-, kunye ne-silicon-containing compounds efana ne-siloxanes);kunye namafutha.Xa kutsha, iikhompawundi ze-halogen kunye nesulfure zenza i-halogen acids, i-SO2, enye i-SO3 kwaye mhlawumbi i-H2SO4 ekhutshwayo.Iiasidi ziyakwazi ukutshabalalisa izixhobo ezisezantsi.Iqhezu elikhulu layo nayiphi na initrogen yamafutha oxidizes kwi-NOx xa ivutha.Ukuthintela umhlwa kunye nokhukuliseko lwamalungu, amasuntswana aqinileyo kufuneka agcinwe kwindawo ephantsi kakhulu.Ukukhuhla amafutha, ukwahlula amathontsi kunye namanyathelo okuhluza kuya kufuneka ukuba nawaphi na amanqanaba ongcoliseko lwepetroli angaphezulu kwemigqaliselo yabavelisi.Irhasi yokulahla inkunkuma isoloko ineekhompawundi zeklorine, iikhompawundi zesulfure, iiasidi ze-organic, kunye neekhompawundi zesilicon, eziyalela ukuba kunyanyekelwe kwangaphambili.

Nje ukuba iphathwe kwaye yamkeleke ukuba isetyenziswe enjinini, iiprofayili zentsebenzo yokukhupha kwezinye izibaso ziyafana nokusebenza kwenjini yegesi yendalo.Ngokukodwa, umlinganiselo wezinto ezikhutshwayo ezisezantsi zeenjini zokutsha ezibhityileyo zinokugcinwa kwezinye izibaso.
