Yiziphi izinzuzo ezivelele zezimoto ze-LNG uma kuqhathaniswa nezimoto ze-CNG?

Inqubo ye Isitshalo esincane se-LNG (isitshalo esincane se-LNG) ikakhulukazi amayunithi ama-4 njengoba kulandelayo.

Imoto ye-LNG ingenye yezindlela ezisetshenziswa kakhulu kuphethiloli we-LNG.

(1) Chaza kafushane inqubo yokugcwaliswa kwezimoto ze-LNG kanye nokuhlinzekwa kwegesi.

Impendulo: Ukugcwaliswa koketshezi: I-LNG igeleza isuka echwebeni lokugcwalisa iye phezulu kwethangi lokugcina nge-valve yendlela eyodwa. Igesi engaphakathi kwethangi iyancishiswa, bese ingcindezi iyehla. Uma igcwaliswe kuze kufike ezingeni loketshezi elilinganisiwe, iyayeka ngokuzenzakalelayo;

Ukunikezwa kwegesi: Lapho injini iqala, i-solenoid valve iyavuleka, bese i-LNG iphuma ngaphansi kwengcindezi ngaphakathi ethangini, ingena ku-vaporizer ukuze kushintshwe ukushisa kanye negesi, bese inikezwa enjinini.

(2) Yiziphi izinzuzo ezivelele zezimoto ze-LNG uma kuqhathaniswa nezimoto ze-CNG?

Impendulo: I-LNG inamandla amaningi (cishe aphindwe kathathu kune-CNG), ibanga elide lokushayela elingaphezu kwamakhilomitha angu-400, futhi igcina amandla kahle futhi ikhipha ukungcola okuncane.

(3) Yiziphi izinzuzo zezimoto ze-LNG uma ziqhathaniswa nezimoto zikadizili?

A. Umnotho. I-1m3 LNG ilingana ne-625N m3 yegesi yemvelo. Ukusebenza kwezimoto zikadizili ezinamandla afanayo amahhashi kubonisa ukuthi i-1m3 yegesi yemvelo ilingana nelitha eli-1 likadizili ongu-0 #, kanti intengo ye-1m3 yegesi yemvelo ingama-yuan angu-5.2 ngophethiloli, okungama-70% entengo yelitha eli-1 likadizili ongu-0 # (7.24 yuan). Lokhu kusho ukuthi ukushintshela kugesi yemvelo yezimoto zikadizili ezinamandla afanayo amahhashi kungonga ama-30% ezindleko. Ibanga lokusebenza lonyaka libalwa ngokusekelwe kumakhilomitha angu-70000 (ukusetshenziswa kukaphethiloli ngamakhilomitha ayi-100 kubalwa ngokusekelwe kumalitha angu-50 edizili noma ama-50m3 egesi yemvelo), okungonga ama-yuan angu-71000 ezindlekweni zikaphethiloli.

B. Ukusebenza kahle kokuphepha. I-LNG inephuzu lokukhanyisa elingu-650 ℃, eliphakeme kunedizili nophethiloli, futhi kunzima ukuyivuthela kunephethiloli nophethiloli. Umkhawulo wokuqhuma kwe-LNG ungu-5% -15%, kanti ubuningi ngemva kokufakwa kwegesi buyingxenye nje yomoya, ngakho uma nje kukhona ukuvuza, kuzonyamalala ngokushesha futhi kusabalale. Ingcindezi yokugcina i-LNG iphansi (0.3-0.7MPa), okwenza iphephe kune-CNG.

C. Ukuvikelwa kwemvelo. Ngenxa yokwakheka kwayo okumsulwa kanye nokungcola okuphansi, izimoto ze-LNG zikhipha amagesi angenangozi kangako njenge-SO2, NOX, kanye ne-CO2, okuwusizo ekuvikelweni kwemvelo.

D. Ithembekile. I-LNG inamandla okuqala kahle okushisa okuphansi futhi ingonga uphethiloli omningi ngezikhathi zokushisa okuphansi. I-LNG inamandla amaningi, futhi amaloli amakhulu e-LNG angahamba amakhilomitha angu-800 kuya kwangu-1000 ngokufaka uphethiloli okukodwa, okungahlangabezana nezidingo zokuhamba ibanga elide. Umthombo wegesi we-LNG wanele futhi ungathuthwa amabanga amade kusetshenziswa amaloli amathangi akhethekile, ngaphandle kokuvinjelwa amapayipi egesi yemvelo.

E. Ukuguqulwa kwezimoto ze-LNG. Inombolo ye-octane yegesi yemvelo ifinyelela ku-130, futhi ukusebenza kwayo okulwa nokungqongqoza kuhle. Ngemva kokuguqulwa kwemoto, impilo yenjini ingandiswa izikhathi ezingaphezu kwezimbili, futhi izindleko zokulungisa ezihambisanayo zingancishiswa ngaphezu kuka-50%. Ubuchwepheshe bamanje bokuguqulwa kwezimoto zasekhaya sebuvuthiwe, futhi utshalomali luvame ukubuyiselwa zingakapheli izinyanga eziyisithupha ngemva kokuguqulwa. Ukuguqulwa kwezimoto ze-LNG kungafinyelelwa ngezindlela ezimbili: eyodwa ukwakha kabusha injini yedizili ekhona ibe yinjini yegesi yemvelo nokufaka uhlelo lokuhlinzeka ngegesi lwe-LNG; Eyesibili ukuthenga izimoto ze-LNG ngqo. Injini iguqulwe yinkampani yobungcweti, iguqula injini yemoto yokuqala ibe yinjini eyodwa kaphethiloli. Ngemva kokuguqulwa, injini ingafinyelela ezingeni lobuchwepheshe lenjini entsha, enokuphila kwamakhilomitha angu-500,000.
