Impulse steam turbine design

U ovome radu opisano je kogeneracijsko postrojenje. Navedene su i opisane vrste kogeneracijskog postrojenja. Osim opisa kogeneracijskog postrojenja u radu se nalazi proračun i crteži za konstrukciju parne turbine snage od 500kW. Parna turbina je toplinski stroj koji entalpiju pare pretvara u mehanički rad, a prije pretvorbe u mehanički rad entalpija pare se pretvara u kinetičku energiju mlaza pare. Upotreba parnih turbina je raznolika, a najčešće se koristi za pogon generatora, kompresora, crpki i brodskih vijaka. Postoji više podjela parnih turbina, a glavne podjele su na prema broju stupnjeva i prema načinu ekspanzije pare koje su detaljnije u radu objašnjene. Za sam proračun bit će konstruirana višestupanjska akcijska parna turbina. Na kraju napravljen je metodički dio, odnosno prikazano gdje se u školama poučava navedena tema i na koje se načine može poboljšati.This paper describes a cogeneraion plant. The types of cogeneration plants are listed and described. In addition to the description of the cogeneration plant, the paper contains a calculation and drawings for the construction of steam turbine with power od 500kW. A steam turbine is a heat engine that converts the steam enthalpy into mehanical work and before converting it into mehanical work, the steam enthalpy is converted into kinetic energy of the steam jet. The use of stem is diverse and it is most often used to drive generators, compressors, pumps and marine propellers. There are sereval divisions of steam turbines and the main are the number of degrees and the way of steam expansion, which are explained in more detail in the paper. A multi-stage action turbine will be constructed for the calculation itself. At the end, a methodical part was made amd it was shown where the mentioned topic is taught in schools an in what ways it can be improved
