Otira kua hiahiatia aha reira, wera motuhake tenei o ngingiha

I muri i te urutaunga o iwi ahi tawhito mo ratou hiahia e rapu tonu mo etahi kōwhiringa hou mo te whakamahi o te ahi, me kora hou. Ko te wahie e whakamahia ana i roto i ngā momo rerekē o combustibles: totoka, wai, haurehu waihā. A ki tenei katoa te wera motuhake o te ngingiha?

Na roto i te tatararaa i te nui o te wera whakaputaina e te parariraa o te 1 kg o te kupiki mārō ranei 1. mita o te taonga haurehu waihā, - ko reira te wera motuhake o te parariraa. Hoki whakamahia tona inenga joule ia kirokaramu (ranei ia mita pūtoru) ranei Calories ia kirokaramu.

Kua i te whakamāramatanga ko reira mārama e te ariā pērā i te wera motuhake o te parariraa taea rite i waenganui i rerekē kora ratou. I roto i te ngako, tenei te tikanga e taea te whiwhi te nui o te pūngao i roto i te puka o te wera i te wae wahie. Katoa taonga, ka kia rerekē tenei uara.

Huri i te reira i roto i taua rakau wera motuhake o te parariraa ko 8,4-11 MJ / kg, engari ka reira waro 15-16 MJ / kg. He aha te tikanga o tenei?

Ko konei, ko te tino māmā mea katoa. homai tetahi manokaramu o waro ka tahuna he tata e rua ngā wā ki runga ake i taua whiwhi e tahu i te manokaramu o te rakau ake wera, a konei e korero tatou e pā ana ki te rakau ki te tetahi haumākū. No te mea ki te he nui te rakau haumākū, he wahi o te pūngao waiariki ka pau i runga i te whakaetonga me te vaporization o te wai i roto i roto i te ngahere, me te hua whakamutunga ka waiho noa kino.

Tonu ko reira taea ki te whakaaro i te tono mahi o tenei ariā ki te toi. haere matou hoki he iti, i roto i te tau o locomotives steam me mua. Mai i te meka e kite tatou i te wera motuhake o te parariraa o te wahie (rakau me te waro) he rerekē i tenei, riro te reira mārama e i roto i te ara ano ki te locomotive rakau tima ranei hiahia ake atu i te waro. O te akoranga, ki te amo tatou e te pūngao noho ratou i runga i te ara i te ara ano, ahakoa o te wahie.

Na whakatika ake tetahi atu mutunga i te tauira i runga ake. E matau te wera motuhake o te parariraa, he reira taea ki te whakatau i te tini o kiromita ka waiho ki te pei i te poti locomotive rere ranei e taea, he supply o te rakau wahie waro ranei. Ki te ki te kaha wahie hanga he hape, na ka mutu waka katoa i runga i te ara.

Kua kua reira he tono mahi i titiro tuatahi kōwhiringa hano me faufaa. Ka taea e koe te whakataurite matū rerekē, me te whakatau i te taea o ratou whakamahi i roto i te āhuatanga ngā rite te wahie, me te ki te aromatawai i te pānga o tenei tono.
