Small biomass nthunzi jenereta otsika nayitrogeni

2. Mapulani achindunji:
(1) Wonjezerani mphepo yachiwiri. Kuti akwaniritse kuyaka kwakuya komanso kocheperako kwa mpweya wa ng'anjo, malo oyaka kwambiri ndi malo obwezeretsa amasiyidwa. Mphuno imodzi yachiwiri ya mpweya imayikidwa pa ngodya inayi ya ng'anjo yamoto (ikhoza kugwedezeka mmwamba ndi pansi, ndipo mpweya wachiwiri umayikidwa pamalo apamwamba kuti utsimikizire kutalika kokwanira kuchira). Njira yachiwiri ya mpweya imakhala ndi khomo lolowera. Ma nozzles apamwamba a mpweya amakhala ndi zisindikizo. Kusintha kwa mpweya wachiwiri ndiye njira yayikulu yowongolera mafuta amtundu wamafuta ndi mtundu wamafuta a NOx.
(2) Muzimitsa mphepo yachitatu. Mpweya wapamwamba kwambiri watsekedwa, ndipo chitoliro choyambirira cha mpweya wapamwamba chimakhala ndi cholekanitsa. Pambuyo podutsa mumlengalenga wolekanitsidwa ndi wandiweyani ndi woonda, mbali yokhuthala imalowa mumlengalenga wachiwiri, ndipo mbali yowala imagwiritsidwa ntchito ngati mpweya wachiwiri. Kubweretsa mpweya wapamwamba mu mpweya wachiwiri kungathe kuchepetsa mpweya wachiwiri wamtundu woyamba woyaka moto. Kuonjezera apo, gawo la malasha ophwanyidwa mumlengalenga wapamwamba likhoza kutumizidwa mu ng'anjo yamoto pasadakhale (poyerekeza ndi malo apamwamba apamwamba), chifukwa Kuchepetsa kwa malowa kulinso kofanana ndi kutalikitsa nthawi yoyaka moto ya malasha ophwanyidwa mu ng'anjo. mu mpweya wapamwamba, zomwe zimapindulitsa kuchepetsa zomwe zimayaka phulusa la ntchentche mu jenereta ya nthunzi.
(3) Kusintha kwa nozzle yachiwiri ya mpweya. Malinga ndi ndondomeko yeniyeni ya kusintha kwa bwalo lachiwiri lakumeta ubweya wamphepo mu ng'anjo, monga momwe tawonetsera pa Chithunzi 1, madera atatu omwe ali ndi makhalidwe osiyanasiyana a m'munda ndi kugawidwa kwa dera lapafupi ndi khoma amapangidwa pa gawo la thupi la ng'anjo. Ikhoza kuonetsetsa kuti pakhoma pali mpweya wokwanira kuti musawononge slagging ndi kutentha kwapamwamba popanda kusintha njira ya jet yaikulu.

Kuyaka njira imeneyi akhoza kusintha permeability wa pulayimale mpweya pulverized malasha otaya mu ng'anjo ndi kusunga kutali madzi khoma m'munsimu, kuchepetsa slagging, mkulu-kutentha dzimbiri ndi mafunsidwe phulusa mafunsidwe mu ng'anjo. Kuphatikiza apo, chifukwa mayendedwe ozungulira mabwalo amphepo a pulayimale ndi yachiwiri ndi mosemphanitsa, ulalo wosakanikirana wa malasha ndi mpweya umachedwa, potero kuchepetsa kutulutsa kwa NOx. Kuonjezera apo, mpweya wachiwiri umayikidwa tangentially, kotero kuti mpweya woyambira umayenda mozungulira mothamanga mumlengalenga wotentha kwambiri kuchokera kumtunda, kotero kuti malasha ophwanyidwa amakhala mosasamala m'derali. Pansi pa kusowa kwa okosijeni, zinthu zosasunthika zimathamangitsidwa mwamsanga ndipo zimayaka ndi kuyaka, zomwe ndizofunikira kwambiri kuti pakhale kuyaka kosasunthika ndi kuyaka. Pali zopindulitsa.
(4) Kusintha kwa kuyatsa kwamafuta ochepa. Kwa ma jenereta ang'onoang'ono a nthunzi, sinthani zoyatsira ziwiri zomwe zili m'munsi mwa jenereta yoyambira ya nthunzi yokhala ndi zoyatsira zochepa za NOX zokhala ndi ntchito yoyatsira mafuta. Chipangizochi chikhoza kupangitsa kuti malasha ophwanyidwawo aziyaka ndikuyaka msanga. Pambuyo pa kusintha, sikoyenera kugwiritsa ntchito mfuti yaikulu ya mafuta pamene jenereta ya nthunzi ikugwira ntchito, yomwe imasunga mafuta ambiri opangira magetsi.
