Hydrocarbon fuels xws li methane (CH4) hlawv nyob rau hauv lub xub ntiag ntawm oxygen mus rau tsim tawm carbon dioxide thiab dej. Qhov no txheej txheem ntawm combustion tso tawm lub zog . Thaum twg zog yog tso tawm Thaum lub sij hawm cov tshuaj tiv thaiv tshuaj, nws tau hais tias yog EXOTHERMIC cov tshuaj tiv thaiv.

Yog li ntawd, dab tsi yog lub zog ntawm combustion?

Chemistry thiab Chemical Technology Lub tshav kub ntawm combustion ( zog cov ntsiab lus) ntawm natural gas yog tus nqi ntawm zog uas tau txais los ntawm kev kub hnyiab ntawm qhov ntim ntawm cov pa roj, ntsuas hauv British thermal units (Btu). Tus nqi ntawm cov nkev yog xam los ntawm nws cov ntsiab lus Btu.

Qhov thib ob, ntau npaum li cas lub zog raug tso tawm hauv combustion ntawm octane? Qhov kub ntawm combustion ntawm octane (C8H18, Mm = 114 g/mol) yog -5500 kJ/mol.

Hais txog qhov no, puas yog txhua qhov kev tawm tsam combustion tso tawm lub zog?

Combustion yog ib oxidation tshuaj tiv thaiv uas ua kom sov, thiab nws yog yog li ntawd ib txwm exothermic. Tag nrho tshuaj cov tshuaj tiv thaiv thawj zaug tawg daim ntawv cog lus thiab tom qab ntawd ua cov tshiab los tsim cov khoom tshiab. Breaking bonds yuav siv sij hawm zog thaum ua daim ntawv cog lus tshiab tso dag zog.

Vim li cas thiaj ua tiav combustion tso tawm ntau zog?

Thaum muaj ntau cov pa oxygen, cov khoom yog carbon dioxide thiab dej. Qhov zoo ntawm combustion tiav yog tias ntau zog yog tso tawm thiab tsis muaj cov pa phem lossis cov kua qaub raug tsim tawm. Ntau zog yog tso tawm thaum combustion tiav tshaj thaum tsis tiav combustion.
