Iyo inoshandiswa kune hombe yekupa mvura pombi yekupfuura ye1,000MW supercritical (ultra-supercritical) unit boiler yekudzora kuyerera kwemvura.
- Ivharuvhu yakatwasuka yemhando yechimiro, yepakati kuyerera inzira yekuyerera uye chisimbiso pamusoro pechigaro chevharuvhu chiri kure nedanho rekupedzisira flash evaporation zone kuvimbisa hupenyu hwesevhisi.
- Muviri wevharuvhu uye bhoneti zvinotora yakaumbwa simbi chimiro chine simba rakawanda kuti isangane nezvinodiwa zvesimba pasi pekushisa kwakanyanya uye kumanikidzwa.
- Inotora chimiro chechigaro chevharuvhu chinobviswa uye chigaro chevharuvhu chine Stellite No. 6 alloy kuvaka-up welding panzvimbo yayo yekuisa chisimbiso.
- Ivhavha disc inotora chimiro chakaenzana uye chisimbiso chepamusoro chinoenda kune yakakwirira frequency quenching; kumusoro uye kuzasi cavities yevhavha disc inoona kudzvanywa kwechiyero kuburikidza nekubatanidza pore. Muchiitiko ichi, vharuvhu inogona kuvharwa nedhiraivha ine dhiraivha shoma.
- Throttle chikamu chevhavha core chakagadzirirwa kutora 6-layer chivharo 5-nhanho yekumanikidza kuderedza chimiro kuparadzira imwechete strand fluid ine simba rakawanda mu-multi-strand fluid ine simba shoma kuderedza kukurumidza uye ruzha. Nhanho-ne-nhanho kuderedza kudzvinyirira kunoitwa neaperture dislocation kubvisa cavitation. Yekupedzisira nhanho sleeve inoita kuti mvura ibve ichitevedza tangent mutsara nzira uye yakatarisana nemukati memuviri wevharuvhu zvisina kunanga kudzikisa scouri kumuviri wevharuvhu.
- Yepakati flange yekuisa chisimbiso inotora mbiri-chisimbiso chimiro che wave zino composite gasket uye elastic simba rekuchengetedza mhete, zvichiita kuti chisimbiso chiwedzere kuvimbika.
- Pasi pemamiriro ekushanda ekuyerera kudiki uye kudzvanywa kwakakura kwakasiyana, multi-nhanho sleeve throttle inogamuchirwa uye nhanho-ne-nhanho kudzikisira kunoitwa nekudzikisira kurongeka kweaperture isina dhayamita isina kuenzana kudzora kuyerera kwepakati kumhanya zvakanyanya uye kuderedza kukanganiswa kwe cavitation uye flash evaporation pavharuvhu. Pasi pemamiriro ekushanda ekuyerera kukuru uye kudzvinyirirwa kuduku kwakasiyana, hwindo rimwe-danho rinogamuchirwa kuti ridzikise kuderedza kuti ive nechokwadi chekuyerera kwevhavha.
- Regulation maitiro anovandudzwa akaenzana muzana, inokwanisa kudzora yepakati kuyerera nemazvo kuti iwane yakanaka yekutonga kuita.
- Iyo vharafu inogona kuve yakashongedzerwa nesarudzo yemagetsi kana pneumatic meshini yekuona nekukurumidza kuvhura nekuvhara uye katatu-kudzivirira.
