Abstract
U ovom radu izrađena je energetska i eksergetska analiza kogeneracijskog postrojenja koje snabdijeva potrošače električnom i toplinskom energijom, odnosno proizvodi visokotlačnu, srednjetlačnu i niskotlačnu paru određenih parametara. S ciljem određivanja energetskog i eksergetskog stupnja iskoristivosti postrojenja potrebno je bilo napraviti: toplinski proračun parne turbine, kondenzatora, potrošača topline, generatora pare i redukcijske stanice. Izračunati rezultati uspoređeni su s rezultatima dobivenim simulacijom postrojenja u programu Ebsilon Professional. Mijenjanjem parametara pare u programu prikazan je utjecaj porasta temperature i/ili tlaka izlazne pare iz generatora pare na ukupnu energetsku iskoristivost. Na temelju energetske i eksergetske analize, odnosno na temelju energetskih i eksergetskih gubitaka komponenata postrojenja, izdvojene su komponente s najvećim gubicima te one predstavljaju najveći potencijal za poboljšavanjem cjelokupnog stupnja iskoristivosti.
Abstract (english)
This paper contains an energy and exergy analysis for cogeneration plant that supplies consumers with electricity and heat, that is, it produces high-pressure, medium-pressure and low-pressure steam of certain parameters. To determine energy and exergetic degree of utilization of the plant it was necessary to do: thermal calculation of steam turbine, condenser, heat consumer, steam generator and reduction station. Calculated results were compared with the results given by the simulation in the program Ebsilon Professional. By changing the steam parameters in the program, the influence of the increase in temperature and/or of the pressure steam output from the generator on the total energy efficiency has been examined. Based on energy and exergy analysis, that is, based on energy and exergy losses of plant components, those components with the largest losses represent the greatest potential for improving the overall degree of efficiency.
