Iyo inoshandiswa kune yakakosha yekupa mvura yekupfuura pombi ye1000MW supercritical (ultra-supercritical) unit boiler yekugadzirisa kuerera kwemvura kuyerera.
- Iyo vharuvhu yakatwasuka mhando dhizaini, yepakati kuyerera nzira ndiko kuyerera mhando uye nekuisa chisimbiso pamusoro pevhavha chigaro chiri kure nenhanho yekupedzisira flash evaporation zone kuvimbisa hupenyu hwebasa.
- Iyo vharuvhu muviri uye bhoneti inotora yakagadzira simbi mamiriro ine yakakwira simba kuti zvirinani kusangana nesimba zvinodiwa pasi yakanyanya tembiricha uye kumanikidza.
- Inotora chinobviswa chivharo chevharuvhu uye chigaro chevhavha chine Stellite Nha. 6 chiwanikwa chekuvaka-kumusoro pachisimbiso chayo.
- Iyo vharuvhu disc inotora yakaenzana mamiriro uye yekuisa chisimbiso pamusoro inoenda yakakwira frequency kudzima; ekumusoro nekudzika matanda evhavha yevhavha inoona kumanikidza chiyero kuburikidza nekubatanidza pore. Muchiitiko ichi, vharafu inogona kuvharwa nedhiraivhoni dhizaini ine shoma dhizaini.
- Throttle chinhu chevharuvhu musimboti yakagadzirirwa kutora 6-dura chifukidzo 5-nhanho kumanikidza kudzikisira mamiriro ekuparadzira imwechete strand fluid ine yakakwira simba kuita kune akawanda-strand fluid ine yakaderera simba yekudzora kumhanya uye ruzha. Nhanho-nhanho-yekumanikidza kudzikisira kunoonekwa nekuvhura disertation kubvisa cavitation. Yekupedzisira nhanho sleeve inoita kuti mvura inoyerera ichitevedza tangent mutsara nzira uye kumeso kwemukati mhango yeiyo vharuvhu muviri zvisina kunangana kudzikisa kurova kune vharafu muviri.
- Middle flange yekuisa chisimbiso inotora mbiri-yekuisa chisimbiso dhizaini zino rinoumbwa gasket uye yakasununguka simba yekuchengetedza mhete, ichiita kuiswa chisimbiso zvakanyanya kuvimbika.
- Pasi pemamiriro ekushanda kwekuyerera kudiki uye hombe kusiyanisa kumanikidza, yakawanda-nhanho sleeve yekumhanya inogamuchirwa uye nhanho-nhanho-yekumanikidza kudzikisira kunoonekwa nekuparadzanisa kurongeka kweaperture isina-yakaenzana dhayamita kudzora wepakati kuyerera kumhanya zvakanyanya uye kudzikisira kukanganisa kwe cavitation uye kupenya kwemvura pavhavha. Pasi pemamiriro ekushanda kwekuyerera kukuru uye diki kusiyanisa kumanikidza, hwindo-rimwe chete hwindo rinogamuchirwa rekumanikidza kudzikisira kuverengera kugona kwevhavha.
- Mitemo yemitemo inovandudzwa yakaenzana muzana, inokwanisa kudzora svikiro kuyerera nenzira kwayo kuti uwane kuita kwakanaka kwekuteedzera.
- Iyo vharuvhu inogona kuve yakashongedzerwa neyakada magetsi kana pneumatic mashandiro ekuona kukurumidza kuvhura nekuvhara uye matatu-kudzivirira.
