Icho chigadzirwa chinoshandiswa kune hwemvura-yemvura system yeabhaira kana emhepo turbine yemafuta anopisa supercritical (ultra-supercritical) unit.
- Muviri wevharuvhu unotora chimiro chakanyatsogadzirwa.
- Simbiso mhando vharuvhu muviri uye bhoneti adopts kumanikidzwa kuzvidzora chisimbiso mamiriro.
- Kuisa chisimbiso pamusoro pechigaro chevharuvhu kune Stellite 6 alloy kuvaka-kumusoro kutenderera.
- Kuisa chisimbiso pamusoro penzvimbo yevhavha yevhavha ine Stellite 12 chiwanikwa chekuvaka-kumusoro.
- Nechigadziko (kana annular kumanikidza kudzikisira paburi) kumberi kwayo, iyo yekuisa chisimbiso pamusoro inogona kudzivirira chidimbu uye kusachena mumapombi kubva pakupwanya iyo yekuisa chisimbiso pamusoro pevhavha yekuvhara.
- Chikamu chekuisa chisimbiso chinotora maviri-nhanho throttle element kumanikidza kudzikisira chimiro uye yepakati kumanikidza kunodzora nhanho nhanho kudzivirira cavitation uye kurova kubva kukuvadza iyo yekuisa chisimbiso pamusoro.
