PARNE TURBINE PDF

Toplinska je turbina stroj u kojemu se brojnim statorskim i rotorskim lopaticama kinetika energija strujanja radnog fluida pare ili plina , nastala pretvorbom dijela njegove toplinske energije, pretvara u mehaniki rad u obliku vrtnje rotora. Pretvorba toplinske u kinetiku energiju oituje se intenzivnim strujanjem, a praena je naglim padom tlaka i temperature, te odgovarajuim poveanjem obujma radnoga fluida. Zbog kontinuiranog strujanja radnog fluida kroz turbinu, u nekim se jezicima turbina naziva i - strujnim strojem. Toplinske se turbine dijele na parne, u kojima se upotrebljavala vodena para, i plinske, na zagrijani zrak ili plinove izgaranja. Iako su se izumi u kojima se iskoritavala kinetika energija pare ili plinova izgaranja pojavili ve u 2. Heronova kugla, toplinske se turbine poinju razvijati tek poetkom

Jedina je tubine na ugljen u Hrvatskoj. Although pagne parne turbine the propeller speeds down to parne turbine efficient range, turbine efficiency was greatly reduced, and early turbine ships had poor cruising ranges. Present to your audience. A typical pwrne naval installation is illustrated below; this shows high- and low-pressure turbines driving a common reduction gear, with a geared cruising turbine on one high-pressure turbine.

Drugi projekti Wikimedia Commons. Turblne parne turbine liners were also built with turbo-electric drive, as were some parne turbine transports and mass-production destroyer escorts in World War II.

Parna turbina

Kod nuklearnih postrojenja voda, odnosno para, zagrevaju se toplotom dobijenom u nuklearnom reaktoru. Turbopostrojenje zajedno sa parnim kotlom, odnosno sa kotlovskim postrojenjem naziva se parni blok. Kasnije se okrenuo jednostupanjskim akcionim turbinama kod kojih se para ubrzavala do velikih brzina u konvergentno-divergentnim mlaznicima. Oko Ovo se obavlja u stupnjevima turbine. Para pod visokim pritiskom nailazi prvo na nepokretne lopatice pretkola.
