Kodi chinyezi cha nthunzi yotentha kwambiri chimaimira chiyani?

Chinyezi nthawi zambiri chimayimira kuchuluka kwa kuuma kwa mumlengalenga.Pa kutentha kwina komanso mu mpweya wina, mpweya wa madzi umakhala wochepa, mpweya umauma;mukakhala nthunzi wamadzi wambiri, mpweyawo umakhala wonyowa kwambiri.Mlingo wa kuuma ndi chinyezi cha mpweya umatchedwa "chinyezi".M'lingaliro limeneli, kuchuluka kwa thupi monga chinyezi chamtheradi, chinyezi chochepa, chinyezi chofananira, chiŵerengero chosakanikirana, machulukidwe ndi mame amagwiritsidwa ntchito pofotokozera.Ngati ikufotokoza kulemera kwa madzi amadzimadzi mu nthunzi yonyowa monga peresenti ya kulemera kwa nthunzi, imatchedwa chinyezi cha nthunzi.

Lingaliro la chinyezi ndi kuchuluka kwa nthunzi yamadzi yomwe ili mumlengalenga.Pali njira zitatu zofotokozera:
1. Chinyezi chamtheradi chikuyimira kuchuluka kwa mpweya wamadzi womwe uli mu kiyubiki mita iliyonse ya mpweya, gawolo ndi kg/m³;
2. Chinyezi, chosonyeza kuchuluka kwa nthunzi wamadzi womwe uli pa kilogalamu ya mpweya wouma, unit ndi kg/kg* mpweya wouma;
3. Chinyezi chofananira chimayimira chiyerekezo cha chinyezi chamtheradi mumpweya ndi chinyontho chodzaza ndi kutentha komweko.Chiwerengerocho ndi peresenti, ndiko kuti, mkati mwa nthawi inayake, kuchuluka kwa nthunzi yamadzi yomwe ili mumlengalenga kwinakwake imagawidwa ndi kuchuluka kwa nthunzi yamadzi pa kutentha kumeneko.peresenti.

Pamene jenereta ya nthunzi ikugwira ntchito, chinyezi chimakhala chochepa kwambiri, mtunda wapakati pa mpweya ndi machulukitsidwe umakhala waukulu, kotero kuti mphamvu yoyamwitsa chinyezi imakhala yamphamvu.Ichi ndichifukwa chake zovala zonyowa zimatha kuuma mosavuta pamasiku adzuwa m'nyengo yozizira.Kutentha kwa mame ndi kutentha kwa babu Monga tanenera poyamba paja, nthunzi wamadzi mumpweya wopanda unsaturated umakhala wotentha kwambiri.

The zonse kuthamanga mapangidwe ndondomeko superheated nthunzi

Agawidwa m'magawo atatu otsatirawa: kuthamanga kosalekeza kwa madzi osatulutsidwa, kutentha kwa madzi osasunthika nthawi zonse, komanso kuthamanga kosalekeza kwa nthunzi yowuma.Kutentha kowonjezera mu nthawi zonse kuthamanga preheating siteji ya madzi unsaturated amatchedwa madzi kutentha;kutentha anawonjezera nthawi zonse kuthamanga vaporization siteji a zimalimbikitsa madzi amatchedwa vaporization kutentha;Kutentha komwe kumawonjezeredwa pagawo lotentha kwambiri la nthunzi yowuma kumatchedwa superheat.

(1) Nthunzi yochuluka: Pakupanikizika kwina, madzi amatenthedwa mpaka kuwira, madzi okhutitsidwawo amayamba kuphwa, ndipo madziwo amasanduka nthunzi pang’onopang’ono.Panthawi imeneyi, kutentha kwa nthunzi kumakhala kofanana ndi kutentha kwa machulukitsidwe.Nthunzi m'derali amatchedwa saturated steam.
(2) Nthunzi yotentha kwambiri ikupitirizabe kutenthedwa pamaziko a nthunzi yodzaza.Kutentha kwa nthunzi ya saturated kuposa kuthamanga kumeneku ndi nthunzi yotentha kwambiri.
