Qhov sib txawv tseem ceeb ntawm tus nqi calorific net thiab tag nrho cov nqi calorific yog tias tus nqi calorific yog tus nqi ntawm cov cua sov uas tsim thaum dej hloov mus rau hauv dej vapor thaum combustion ntawm ib yam khoom, whereas tag nrho cov nqi calorific yog tus nqi. cua sov tsim thaum dej hloov mus rau hauv dej vapor thiab rov qab mus rau lub xeev ua kua.
Tus nqi Calorific yog qhov tseem ceeb rau kev txhais cov ntsiab lus nquag ntawm cov khoom sib txawv. Peb tuaj yeem hu nws feem ntau raws li tus nqi calorific tag nrho lossis raws li tus nqi cua sov siab. Tus nqi calorific net, ntawm qhov tod tes, yog qhov rho tawm ntawm cov cua sov ntawm vaporization ntawm cov dej vapor los ntawm tag nrho cov nqi calorific. Tus nqi calorific net kuj hu ua tus nqi cua sov tsawg.
Tus nqi Calorific yog dab tsi?
Tus nqi calorific yog qhov rho tawm ntawm cov cua sov ntawm vaporization ntawm cov dej los ntawm cov nqi cua sov siab. Qhov kev ntsuas no tseem hu ua tus nqi qis dua (LHV) lossis qis dua calorific nqi (LCV). Qhov kev ntsuas no feem ntau xav tias cov dej tivthaiv ntawm cov txheej txheem combustion tshwm sim hauv lub xeev vapor thaum lub sijhawm kawg ntawm cov txheej txheem combustion. Qhov kev xav no yog qhov sib txawv ntawm tus nqi calorific tag nrho (nws xav tias tag nrho cov dej ntsiab lus hauv cov txheej txheem combustion tshwm sim hauv cov kua dej thaum kawg ntawm cov txheej txheem combustion.
Thaum sib piv cov roj sib txawv, tus nqi calorific net tseem ceeb dua li tus nqi calorific tag nrho. Qhov no yog ib qho tseem ceeb thaum lub condensation ntawm cov khoom combustion tsis siv tau. Lossis, nws yog ib qho tseem ceeb thaum tshav kub kub tsis tuaj yeem muab tso rau hauv ib qho kev siv.
Feem ntau, txhawm rau txiav txim siab tus nqi calorific, peb tuaj yeem siv cov txheej txheem European uas siv tus nqi calorific tag nrho. Tus nqi calorific tag nrho yog tus nqi sim. Rau qhov kev suav no, peb yuav tsum paub cov pa oxygen, nitrogen, thiab hydrogen cov ntsiab lus ntawm cov qauv. Ntxiv mus, tus nqi calorific net nyob ntawm qhov qhuav ntawm cov qauv.
Tus nqi Calorific tag nrho yog dab tsi?
Tus nqi calorific tag nrho yog tus nqi hluav taws xob uas tsim los ntawm kev ua tiav tag nrho ntawm ib chav tsev ntim ntawm cov khoom. Nws yog tus nqi tiag tiag ntawm lub zog tshwj xeeb ntawm combustion rau ib chav tsev loj ntawm cov khoom. Nws yog ib qho parameter uas tseem ceeb hauv kev txhais cov ntsiab lus nquag ntawm qee cov ntaub ntawv. Peb feem ntau tuaj yeem hu nws tus nqi calorific lossis cov nqi cua sov siab. Chav ntsuas ntawm qhov ntsuas no yog KJ / kg.
Nws yog ib qho tseem ceeb heev los ntsuas qhov tag nrho calorific tus nqi ntawm cov roj los yog zaub mov vim hais tias cov efficiency ntawm roj los yog zaub mov nyob ntawm tus nqi calorific. Yog li ntawd, qhov siab dua tus nqi tag nrho calorific, qhov ua tau zoo dua thiab rov ua dua. Qhov no txhais tau tias tag nrho cov nqi calorific ncaj qha proportional rau cov efficiency. Ntxiv mus, tus nqi calorific siab sawv cev rau cov ntsiab lus ntawm cov dej vapor generated thaum lub sij hawm combustion txheej txheem, thiab cov khoom rov qab los ntawm ntau hom kev kawm thiab vice versa.
Qhov Sib Txawv Ntawm Tus Nqi Net Calorific thiab Tag Nrho Calorific Tus Nqi
Tus nqi Calorific yog qhov tseem ceeb rau kev txhais cov ntsiab lus nquag ntawm cov khoom sib txawv. Nws muaj ob hom xws li net thiab tag nrho cov nqi calorific. Qhov sib txawv tseem ceeb ntawm tus nqi calorific thiab tag nrho cov nqi calorific yog tias tus nqi calorific yog tus nqi ntawm cov cua sov uas tsim thaum dej hloov mus rau hauv dej vapor thaum combustion ntawm cov khoom, whereas tag nrho cov nqi calorific yog tus nqi ntawm cov cua sov tsim thaum dej. hloov mus rau hauv dej vapor thiab rov qab mus rau lub xeev ua kua.
Cov lus hauv qab no teev qhov sib txawv ntawm tus nqi calorific net thiab tag nrho cov nqi calorific hauv daim ntawv.
Summary – Net Calorific Value vs Gross Calorific Value
Tus nqi Calorific yog qhov tseem ceeb rau kev txhais cov ntsiab lus nquag ntawm cov khoom sib txawv. Nws muaj ob hom xws li net thiab tag nrho cov nqi calorific. Qhov sib txawv tseem ceeb ntawm tus nqi calorific thiab tag nrho cov nqi calorific yog tias tus nqi calorific yog tus nqi ntawm cov cua sov uas tsim thaum cov dej hloov mus rau hauv dej vapor thaum combustion ntawm cov khoom, whereas tag nrho cov nqi calorific yog tus nqi ntawm cov cua sov tsim thaum dej. hloov mus rau hauv dej vapor thiab rov qab mus rau lub xeev ua kua.
