1,Basic Kutembenuka Ubale
1. Ubale wogwirizana pakati pa mphamvu ndi voliyumu ya nthunzi
-Nthunzi yotentha: 1 ton/ola (T/h) ya nthunzi imafanana ndi mphamvu yotentha ya pafupifupi 720 kW kapena 0.7 MW.
- Ng'anjo yamafuta otentha: Kutembenuka pakati pa mphamvu yamagetsi yamagetsi (kW) ndi voliyumu ya nthunzi kuyenera kukwaniritsidwa kudzera pakutentha (kJ/h). Mwachitsanzo, ngati mphamvu ya ng'anjo yamafuta otentha ndi 1400 kW, voliyumu ya nthunzi yofananira ndi pafupifupi matani 2 / ola (yowerengedwa ngati tani 1 ya nthunzi ≈ 720 kW).
2. Kutembenuka kwa magawo amphamvu amafuta
-1 tani ya nthunzi ≈ 600000 kcal / h ≈ 2.5GJ / h.
-Kugwirizana pakati pa mphamvu yamagetsi yamagetsi (kW) ndi kutentha: 1kW = 860kcal / h, choncho 1400kW mphamvu yamagetsi yamagetsi ikufanana ndi 1.204 miliyoni kcal / h (pafupifupi matani 2.01 a nthunzi).
2,Njira yosinthira ndi magawo
1. Kuwerengera chilinganizo cha mphamvu yamagetsi yamagetsi
\-Mafotokozedwe a Parameter:
-(P): Mphamvu yamagetsi yamagetsi (kW);
-(G): Kuchuluka kwa sing'anga kutentha (kg/h);
-(C): Enieni kutentha mphamvu sing'anga (kcal/kg · ℃);
-\ (\ Delta t \): Kusiyana kwa kutentha (℃);
-(eta): Kutentha kwamafuta (nthawi zambiri kumatengedwa ngati 0.6-0.8).
2. Chitsanzo cha kuwerengera kuchuluka kwa nthunzi
Kungoganiza kuti 1000kg ya mafuta otumizira kutentha iyenera kutenthedwa kuchokera ku 20 ℃ mpaka 200 ℃ (Δ t = 180 ℃), kutentha kwapadera kwa mafuta otengera kutentha ndi 0.5kcal / kg · ℃, ndipo kutentha kwake ndi 70%:
\ Voliyumu ya nthunzi yofananira ndi pafupifupi matani 2.18 / ola (yowerengeredwa potengera 1 toni ya nthunzi ≈ 720kW).
3,Zosintha pazogwiritsa ntchito
1. Kusiyana kwa kutentha kwa kutentha
-Kuchita bwino kwang'anjo yamafuta otentha yamagetsinthawi zambiri ndi 65% -85%, ndipo mphamvu iyenera kusinthidwa malinga ndi momwe zimagwirira ntchito.
-Ma boilers achikale amakhala ndi mphamvu pafupifupi 75% -85%, pomwemakina otenthetsera magetsikukhala ndi mphamvu zambiri chifukwa chosowa kuyaka kwamafuta.
2. Mphamvu ya makhalidwe apakati
-Kutentha kwapadera kwa mafuta otentha (monga mafuta amchere) ndi pafupifupi 2.1 kJ / (kg · K), pamene madzi ndi 4.18 kJ / (kg · K), omwe amafunika kusinthidwa molingana ndi sing'anga yowerengera.
-Kutentha kwapamwamba (monga pamwamba pa 300 ℃) kumafuna kulingalira za kukhazikika kwa kutentha kwa mafuta otengera kutentha ndi kuthamanga kwa dongosolo.
3. Mphepete mwa mapangidwe a dongosolo
-Pezani kuonjezera malire achitetezo a 10% -20% pazotsatira zowerengera kuti muthane ndi katundu wosinthasintha.
4,Nkhani Yodziwika bwino
-Mlandu 1: Fakitale yamankhwala achi China imagwiritsa ntchito jenereta ya nthunzi yamagetsi ya 72kW, yofanana ndi kuchuluka kwa nthunzi pafupifupi 100kg / h (yowerengedwa ngati 72kW × 0.7 ≈ 50.4kg / h, magawo enieni amayenera kuphatikizidwa ndi zida za nameplate).
-Mlandu 2: A 10 mataning'anjo yamafuta otentha(yokhala ndi mphamvu ya 7200kW) imatenthetsa mpaka 300 ℃, ndikugwiritsa ntchito mphamvu pachaka pafupifupi 216 miliyoni kWh ndi voliyumu yofananira ya nthunzi pafupifupi matani 10000 pachaka (kutengera 720kW = tani 1 ya nthunzi).
5,Kusamalitsa
1. Kusankha zida: Kusankhidwa kolondola kuyenera kupangidwa malinga ndi kutentha kwa ndondomeko, mtundu wapakati, ndi kutentha kwa kutentha kuti tipewe mphamvu zosakwanira kapena zowonongeka.
2. Malamulo achitetezo: Ntchito yotchinjiriza yamagetsi kutentha dongosoloziyenera kuyang'aniridwa nthawi zonse, ndipo kupanikizika ndi kutayikira kwa kayendedwe ka nthunzi ziyenera kuyang'aniridwa.
3. Kukhathamiritsa kwamphamvu kwamphamvu: Themagetsi kutentha dongosoloItha kupulumutsanso mphamvu kudzera pakuwongolera pafupipafupi komanso kuwononga kutentha.
Pazigawo za zida zinazake kapena kuwerengera makonda, tikulimbikitsidwa kutchula bukhu laukadaulo la wopanga kapena kulumikizana ndi akatswiri odziwa ntchito.
Ngati mukufuna kudziwa zambiri za mankhwala athu, chondetiuzeni!
