1,Ubudlelwano Bokuguqulwa Okuyisisekelo
1. Ubudlelwano obuhambelanayo phakathi kwamandla nevolumu yesitimu
-Isibhakela somusi: Ithani elingu-1/ihora (T/h) lesitimu lihambisana namandla ashisayo acishe abe ngu-720 kW noma angu-0.7 MW.
-Isithando somlilo esishisayo: Ukuguqulwa phakathi kwamandla okushisa kagesi (kW) kanye nevolumu yesitimu kudinga ukutholwa ngomthwalo wokushisa (kJ/h). Isibonelo, uma amandla esithandweni somlilo esishisayo engu-1400 kW, ivolumu ye-steam ehambisanayo cishe ngamathani angu-2 / ihora (kubalwa njenge-1 ton of steam ≈ 720 kW).
2. Ukuguqulwa kwamayunithi wamandla ashisayo
-1 ithani lomusi ≈ 600000 kcal / h ≈ 2.5GJ/h.
-Ubudlelwano phakathi kwamandla okushisa kagesi (kW) nokushisa: 1kW=860kcal/h, ngakho-ke amandla okushisa kagesi angu-1400kW ahambisana ne-1.204 million kcal/h (cishe amathani angu-2.01 wesitimu).
2,Ifomula yokuguqulwa namapharamitha
1. Ifomula yokubala yamandla okushisa kagesi
\-Incazelo yepharamitha:
-(P): Amandla okushisa kagesi (kW);
-(G): Isisindo sokushisisa (kg/h);
-(C): Umthamo wokushisa othize we-medium (kcal/kg ·℃);
-\ (\ Delta t \): Umehluko wezinga lokushisa (℃);
-(eta): Ukusebenza kahle kokushisa (ngokuvamile kuthathwa njengo-0.6-0.8).
2. Isibonelo sokubala inani le-steam
Uma sicabanga ukuthi u-1000kg kawoyela wokudlulisa ukushisa udinga ukushisisa ukusuka ku-20 ℃ kuye ku-200 ℃ (Δ t=180 ℃), amandla athile okushisa okushisa okudluliswayo ngu-0.5kcal/kg ·℃, kanti ukusebenza kahle okushisayo kungu-70%:
\Ivolumu yesitimu ehambisanayo icishe ibe ngamathani angu-2.18/ihora (ibalwa ngokusekelwe kuthani elingu-1 lesitimu ≈ 720kW).
3,Izinto zokulungisa ezinhlelweni ezisebenzayo
1. Umehluko ekusebenzeni kahle kwe-thermal
-Ukusebenza kahle kweisithando somlilo esishisayo sikagesi esishisayongokuvamile i-65% -85%, futhi amandla adinga ukulungiswa ngokuvumelana nokusebenza kahle kwangempela.
-Ama-boilers wendabuko asebenza kahle cishe ngo-75% -85%, kuyilaphoamasistimu okushisa kagesiabe nokusebenza kahle okuphezulu ngenxa yokungabikho kokulahleka kokushiswa kukaphethiloli.
2. Ithonya lezici ezimaphakathi
-Umthamo othize wokushisa wamafutha ashisayo (njengamafutha amaminerali) cishe u-2.1 kJ/(kg · K), kanti owamanzi ungu-4.18 kJ/(kg · K), odinga ukulungiswa ngokuvumelana nendawo yokubala.
-Izimo zokushisa eziphezulu (ezifana nangaphezulu kuka-300 ℃) zidinga ukucatshangelwa kokuzinza okushisayo kwamafutha okudlulisa ukushisa nokucindezela kwesistimu.
3. Imajini yedizayini yesistimu
-Phakamisa ukungeza imaji yokuphepha engu-10% -20% emiphumeleni yokubala ukuze ubhekane nemithwalo eguquguqukayo.
4,Ireferensi Yekesi Ejwayelekile
-Icala loku-1: Imboni yemithi yendabuko yamaShayina isebenzisa i-72kW generator yesitimu kagesi, ehambisana nevolumu ye-steam engaba ngu-100kg / h (ebalwa njenge-72kW × 0.7 ≈ 50.4kg / h, imingcele yangempela idinga ukuhlanganiswa nama-nameplates emishini).
-Icala 2: A 10 tonisithando somlilo esishisayo(enamandla angu-7200kW) ifudumeza kufika ku-300 ℃, ngamandla asetshenziswa ngonyaka cishe ayizigidi ezingama-216 kWh kanye nevolumu yesitimu ehambisanayo ecishe ibe ngamathani ayi-10000 ngonyaka (kuthatha u-720kW=1 ton of steam).
5,Izinyathelo zokuzivikela
1. Ukukhethwa kwezisetshenziswa: Ukukhetha okunembile kufanele kwenziwe ngokusekelwe ekushiseni kwenqubo, uhlobo oluphakathi nendawo, nomthwalo wokushisa ukuze kugwenywe amandla anganele noma imfucuza.
2. Imithethonqubo yokuphepha: Ukusebenza kwe-insulation of theisistimu yokushisa kagesiidinga ukuhlolwa njalo, futhi ingcindezi kanye nengozi yokuvuza yesistimu yesitimu kudingeka iqashwe.
3. Ukusebenza kahle kwamandla: Iisistimu yokushisa kagesiingaqhubeka yonga amandla ngokulawula ukuguqulwa kwemvamisa kanye nokumosha ukubuyiswa kokushisa.
Ukuze uthole amapharamitha wemishini ethile noma izibalo ezenziwe ngokwezifiso, kunconywa ukuthi ubhekisele kumanuwali obuchwepheshe bomenzi noma uxhumane nochwepheshe abaqeqeshiwe.
Uma ufuna ukwazi okwengeziwe ngomkhiqizo wethu, sicelaXhumana nathi!
