Kugadziriswa kweNatural Gasi Injini Jenareta

Nhasi Dingbo Power inogovera nzira dzekuchengetedza dzegasi injini jenareta, tariro inobatsira kwauri.

Mari yekuchengeta inosiyana nerudzi, kumhanya, saizi uye nhamba yemasilinda einjini.Iyi mari inowanzo sanganisira:

• Basa rekuchengetedza

• Zvikamu zveinjini uye zvinhu zvakadai semafuta emafuta, mafirita emhepo, spark plugs, gaskets, mavharuvhu, piston mhete, zvinhu zvemagetsi, nezvimwewo uye zvinoshandiswa zvakadai semafuta.

• Kugadziridza kudiki uye kukuru.

Kuchengetedza kunogona kuitwa nevashandi vepamba kana kupihwa chibvumirano kune vanogadzira, vanogovera, kana vatengesi vari pasi pezvibvumirano zvebasa.Zvibvumirano zvekugadzirisa zvizere (zvinovhara masevhisi ese anokurudzirwa) zvinowanzoita pakati pe1 kusvika 2.5 cents/kWh zvichienderana nekukura kweinjini, kumhanya uye sevhisi.Zvibvumirano zvakawanda zvebasa zvino zvinosanganisira kutarisisa kure kwekuita kweinjini uye mamiriro mukuwedzera kune kubvumira kufembera kugadzirisa.Mari dzekondirakiti dzebasa dzinowanzo sanganisira zvese, kusanganisira nguva yekufamba yevanyanzvi pakufona kwesevhisi.

Sevhisi inokurudzirwa inosanganisira yenguva pfupi yekuongorora / kugadziridzwa uye nguva nenguva kutsiva mafuta einjini nemasefa, inotonhorera, uye spark plugs (kazhinji maawa mazana mashanu kusvika zviuru zviviri).Oiri kuongororwa chikamu cheakawanda ekudzivirira ekuchengetedza zvirongwa zvekutarisa kupfeka kweinjini.Kugadziridza kwepamusoro-soro kunowanzokurudzirwa pakati pe8,000 ne30,000 maawa ekushanda (ona Tafura 2-5) iyo inosanganisira silinda musoro uye turbocharger kuvaka patsva.Kuwedzeredza kukuru kunoitwa mushure memaawa makumi matatu kusvika makumi manomwe nemakumi manomwe ezviuru ekushanda uye kunosanganisira kutsiva piston/liner, kuongorora crankshaft, mabearings, uye zvisimbiso.Nguva dzekuchengetedza dzinoratidzwa muTable 2-5.

Mari yekugadziridza inoratidzwa muTable 2-6 yakavakirwa pafungidziro yevagadziri veinjini yezvibvumirano zvesevhisi zvinosanganisira kuongororwa kwechinyakare uye kurongerwa kugadziridzwa kweseti yejenareta.Mutengo unobva pa8,000 maawa ekushanda epagore anoratidzwa maererano nekugadzirwa kwemagetsi pagore.Kugadziriswa kweinjini kunogona kuputswa kuita zvikamu zvakagadzika zvinoda kuitwa nguva nenguva zvisinei neinjini yekumhanyisa nguva uye zvikamu zvinoshanduka zvinoenderana nemaawa ekushanda.Vatengesi vakatora mari yese yeO&M pane inosiyana-siyana yehurongwa hwebasa rekushandisa.

2.4.7 Mafuta

Pamusoro pekushanda pagasi rechisikigo, injini dzekudzima moto dzinoshanda pane akasiyana siyana mamwe magasi anosanganisira:

• Liquefied petroleum gas (LPG) - propane uye butane musanganiswa

• Gasi rakasvibirira - risina kushandiswa gasi rechisikigo sezvo rinouya zvakananga kubva kune gasi tsime.

• Biogas - chero magasi anopisa anogadzirwa kubva mukuparara kwebiological tsvina, segasi remarara, sewage digester gasi, nemarara emhuka.

• Magasi emarara emumaindasitiri - anopisa magasi uye anobvisa-magasi kubva munzvimbo dzinocheneswa, zvidyarwa zvemakemikari uye chigayo chesimbi.

• Magasi anogadzirwa - kazhinji akaderera- uye epakati-Btu gasi anogadzirwa sezvigadzirwa zvegasification kana pyrolysis maitiro Zvinhu zvinokanganisa kushanda kweinjini yekubatidza spark ine mamwe mafuta ane gasi zvinosanganisira:

• Volumetric heat value - Sezvo mafuta einjini achiendeswa pahuwandu, huwandu hwemafuta muinjini hunowedzera sezvo kukosha kwekudziya kunoderera, zvinoda kudzikiswa kweinjini pamafuta ane Btu yakaderera.Derating inonyanya kutaurwa neinjini dzinoshuvira, uye zvichienderana nezvinodiwa nemhepo, turbocharging zvishoma kana zvachose inobhadhara.

• Autoignition maitiro uye detonation tendency yemafuta ane yakaderera octane rating se propane - Izvi zvinowanzo onekwa nehukoshi hwakaverengerwa hunozivikanwa seMethane.

Nhamba (MN).Different vagadziri vegasi jenareta inogona kuverenga Methane Nhamba zvakasiyana.Magasi ane huremu hwema hydrocarbon components (Propane, Ethane, Butane, etc.) ane Methane Number yakaderera sezvo achizoita autoignite zviri nyore.

• Zvakasvibiswa zvinogona kukanganisa hupenyu hweinjini kana kugadzirisa kweinjini, kana kukonzera kusvibiswa kwemhepo kunoda mamwe matanho ekudzora.

• Mafuta ane haidrojeni angada matanho akakosha (kazhinji kana hydrogen zviri mukati nehukuru yakakura kupfuura zvikamu zvishanu kubva muzana) nekuda kwekupisa kwehydrogen uye kuputika.

Tafura 2-7 inomiririra zvinomiririra mamwe emamwe mafuta egasi anoenzaniswa negasi rechisikigo.Marara emaindasitiri uye magasi anogadzirwa haana kubatanidzwa mutafura nekuti maumbirwo awo anosiyana zvakanyanya zvichienderana nekwaanobva.Iwo anowanzo ane mazinga akakosha eH2 uye/kana CO. Zvimwe zvinoumba CO2, mhute yemvura, imwe kana kupfuura mahydrocarbon emwenje, uye H2S kana SO2.

Kusvibiswa kunonyanya kunetseka nemafuta akawanda emarara, kunyanya maasidhi egasi (H2S, halogen acids, HCN; ammonia; munyu uye masimbi ane simbi; organic halogen-, sulfur-, nitrogen-, uye silicon-containing compounds yakadai sesiloxanes);uye mafuta.Mukupisa, halogen uye sulfur makomisheni anoumba halogen acids, SO2, mamwe SO3 uye pamwe H2SO4 emissions.Maasidhi anogonawo kukanganisa midziyo yakadzika.Chikamu chakakura chechero mafuta nitrogen oxidize muNOx mukupisa.Kudzivirira kukora uye kukukurwa kwezvikamu, zvimedu zvakasimba zvinofanirwa kuchengetwa zvakadzika zvakanyanya.Yakasiyana-siyana yekukwesha mafuta, kupatsanurwa kwemadonhwe uye matanho ekusefa anozodiwa kana chero mazinga emafuta anosvibisa akadarika zvakatemwa nevagadziri.Gasi rekuzadza marara kunyanya kazhinji rine chlorine makomisheni, sulfur makomisheni, organic acids, uye silicon makomponi, ayo anoraira pretreatment.

Kana yangorapwa uye yagamuchirwa kuti ishandiswe muinjini, emissions performance profiles pane mamwe mafuta akafanana neakasikwa gasi injini kuita.Kunyanya, iyo yakaderera emissions ratings yeakaonda kupisa injini kazhinji inogona kuchengetedzwa pane mamwe mafuta.
