He aha ngā painga nui o ngā waka LNG ki te whakataurite ki ngā waka CNG?

Te tukanga o Te Whare Hanga Waipiro iti (te tipu LNG iti) e whā ngā waeine matua e whai ake nei.

Ko te waka LNG tētahi o ngā waka e whakamahia nuitia ana mō te wahie LNG.

(1) Whakaahuahia pototia te tukanga whakakī waka LNG me te tuku hau.

Whakautu: Te whakakī wai: Ka rere te LNG mai i te putanga whakakī ki te tihi o te tāke rokiroki mā te takirere kotahi-ara. Ka whakakōkīhia te hau i roto i te tāke, ā, ka heke te pēhanga. Ina whakakīia ki te taumata wai kua whakatauria, ka mutu aunoa;

Tuku hau: Ina tīmata te mīhini, ka tuwhera te takirere solenoid, ka rere te LNG i raro i te pēhanga i roto i te tāke, ka tomo ki te vaporizer hei whakawhiti wera me te whakapūhautanga, ā, ka tukuna ki te mīhini.

(2) He aha ngā painga nui o ngā waka LNG ki te whakataurite ki ngā waka CNG?

Whakautu: He nui te kaha o te LNG (tata ki te toru ngā wā i te CNG), he roa te tawhiti taraiwa neke atu i te 400km, ā, he pai ake te whakamahi i te kaha me te iti ake o ngā tukunga.

(3) He aha ngā painga o ngā waka LNG ki te whakataurite ki ngā waka tīhiera?

A. Ōhanga. Ko te 1m3 LNG he rite ki te 625N m3 o te hau māori. Ko te whakahaere o ngā waka tīhiera me te kaha hōiho ōrite e whakaatu ana ko te 1m3 o te hau māori he rite ki te 1 rita o te tīhiera 0 #, ā, ko te utu o te 1m3 o te hau māori he tata ki te 5.2 yuan mō te penehīni, arā, 70% o te utu o te 1 rita o te tīhiera 0 # (7.24 yuan). Ko te tikanga o tēnei, mā te huri ki te hau māori mō ngā waka tīhiera me te kaha hōiho ōrite ka taea te penapena i te 30% o te utu. Ka tatauhia te maero whakahaere ā-tau i runga i te 70000 kiromita (ka tatauhia te kai wahie mō ia 100 kiromita i runga i te 50 rita o te tīhiera, 50m3 rānei o te hau māori), ka taea te penapena i te 71000 yuan i roto i ngā utu wahie.

B. He pai te mahi haumaru. Ko te pūwāhi mura o te LNG he 650 ℃, he teitei ake i te tīhiera me te penehīni, ā, he uaua ake te mura i te penehīni me te tīhiera. Ko te rohe pahūtanga o te LNG he 5% -15%, ā, ko te mātotorutanga i muri i te whakapūngatanga hau he haurua noa iho i te hau, nō reira, mena he turuturu, ka mimiti tonu, ka horapa. He iti te pēhanga rokiroki LNG (0.3-0.7MPa), he haumaru ake i te CNG.

C. Te tiaki taiao. Nā te mea he parakore te hanganga me te iti o ngā poke, he iti ake te kino o ngā hau e tukuna ana e ngā waka LNG pēnei i te SO2, te NOX, me te CO2, he mea pai mō te tiaki taiao.

D. Pono. He pai te mahi tīmatanga pāmahana iti o te LNG, ā, ka taea te penapena wahie i ngā wā pāmahana iti. He nui te kaha o te LNG, ā, ka taea e ngā taraka LNG nunui te haere tonu i te 800 ki te 1000 kiromita me te whakakī anō i te hinu kotahi, ka taea ai te whakatutuki i ngā hiahia kawe tawhiti. He rawaka te puna hau LNG, ā, ka taea te kawe i ngā tawhiti roa mā te whakamahi i ngā taraka tāke motuhake, me te kore e herea e ngā paipa hau maori.

E. Te whakarerekētanga o ngā waka LNG. Ko te tau octane o te hau māori he teitei ki te 130, ā, he pai te mahi ārai-patuki. I muri i te whakarerekētanga o te waka, ka taea te whakaroa ake i te roa o te ora o te miihini neke atu i te 2 ngā wā, ā, ka taea te whakaiti i ngā utu tiaki e rite ana neke atu i te 50%. Kua pakari te hangarau whakarerekētanga ā-rohe o nāianei, ā, ko te nuinga o te wā ka whakahokia mai te haumitanga i roto i ngā marama e ono i muri i te whakarerekētanga. Ka taea te whakatutuki i te whakarerekētanga o ngā waka LNG mā roto i ngā huarahi e rua: ko te tuatahi ko te hanga anō i te miihini tīhiera o nāianei hei miihini hau māori me te tāuta i tētahi pūnaha tuku hau LNG; ko te tuarua ko te hoko tika i ngā waka LNG. Kua hurihia te miihini e tētahi kamupene ngaio, ka hurihia te miihini motuka taketake hei miihini wahie kotahi. I muri i te whakarerekētanga, ka taea e te miihini te eke ki te taumata hangarau o tētahi miihini hou, me te roa o te ora o te 500,000 kiromita.
