Ta yaya ne konewa dauki

Goren kira hadawan abu da iskar shaka dauki abin da ya auku a high gudun, wanda yana tare da zafi a cikin manyan yawa da kuma, kamar yadda mai mulkin, da wata mai haske haske, wanda muke kira harshen wuta. A konewa aiwatar nazarin jiki sunadarai, a cikin abin da wani konewa aka yarda to duk exothermic matakai da ciwon kai-accelerating dauki. Irin kai-hanzari iya zama saboda kara a zazzabi (t. E. Shin, wani zafi engine), ko jari na cikin aiki barbashi (ciwon yadawa halitta).

A konewa dauki wani gani fasalin - gaban high zazzabi yankin (da harshen wuta), spatially takaitawa da kuma inda mafi yawan hira auku fara kayan (man fetur) a cikin konewa kayayyakin. Wannan tsari yana tare da a saki babban adadin thermal makamashi. Don fara da dauki (harshen wuta bayyanar) da ake bukata don ciyar wani adadin kuzari a kan ƙonewa, sa'an nan kan aiwatar da ke spontaneously. Its gudun dogara da sinadaran Properties daga cikin abubuwa da hannu a cikin dauki, kazalika da irin yadda gas tsauri matakai a lokacin konewa. A konewa dauki yana da wasu halaye, mafi muhimmanci daga wanda - da kuma calorific darajar daga cikin cakuda ne da yawan zafin jiki (da ake kira adiabatic), wanda zai iya rubuce a iya cimma tare da cikakken konewa ban da kadan.

By tara jihar oxidizer da kuma man fetur konewa tsari za a iya sanya daya daga uku iri. A konewa dauki iya zama:

- kama a lokacin da man fetur da kuma oxidizer (pre-gauraye) ne a cikin gaseous jihar,

- iri-irin, a cikin abin da m ko ruwa man fetur reacts tare da oxidant gas,

- dauki na konewa na gunpowder da kuma bama-bamai.

Kama konewa ne mafi sauki, yana da wani m gudun, dangane da abun da ke ciki da kuma kwayoyin zafi madugu cakuda, zafin jiki da kuma matsa lamba.

Iri-irin konewa ne ya fi kowa a cikin yanayi, kazalika da a vitro. Its gudun shi ne dogara a kan takamaiman yanayi na konewa aiwatar da jiki halaye na sinadaran. A cikin ruwa da man fetur zuwa konewa gudun aka samo asali ne daga cikin kudi na danshin, a m - gasification kudi. Alal misali, cikin tsari suranta matakai biyu a lokacin da kwal konewa. A farko daga gare su (a cikin hali na wani comparatively m dumama) kasaftawa volatiles abu (ci), to da na biyu konewa coke.

Konewa gas (msl, ethane konewa) ne daban-daban. A gaseous matsakaici iya propagate bira a sararin nesa. Yana iya matsar da gas a wata subsonic gudun, tare da dukiya da ba kawai a gaseous matsakaici, amma kuma a cakuda lafiya ruwa da kuma m combustible barbashi gauraye da oxidant. Don tabbatar da barga konewa a irin haka na bukatar musamman zane na makera na'urar.

Sakamakon wanda ya haddasa konewa dauki a gaseous matsakaici, ne na iri biyu. Farko - a halin rashin kwanciyar hankali a gas da kwarara, abu zuwa kaifi karuwa a aiwatar gudun. Kunno kai tare da Ft Irfan disturbances iya haifar da ya kwarara zuwa gaba mataki - fitowan na buga kalaman manyan zuwa fasa daga cikin cakuda. Hasken Rana fasa konewa mataki dogara ba kawai a kan kansa gas Properties amma kuma daga tsarin da yaduwa sigogi masu girma dabam.

A konewa na man fetur a yi amfani da fasaha da masana'antu. Babban maƙasudin nan shi ne a cimma matsakaicin konewa yadda ya dace (watau. E. Don inganta zafi) ga wata qaddara tazara. Amfani da kona, misali, a karafa masana'antu - ci gaban da hanyoyi daban-daban na ma'adanai dogara ne a kan yin amfani da aiwatar da man fetur. Amma a wasu halitta da kuma yanki yanayi na konewa sabon abu zai iya zama wani factor, ɗauke da tsanani hadari. A Hatsarin, misali, shi ne a aiwatar da maras wata-wata konewa na peat, wadda take kaiwa zuwa bayyanar na ciki gobara.
