Exergy Analysis of Thermal Power Plant for Three Different Loads

This paper presents the energy and exergy analysis of thermal power plant Tuzla in Tuzla, Bosnia Herzegovina. The main aim this is to analyze components a 200 MW steam unit order identify quantify sites with highest losses calculate efficiency values all when operating at nominal load. influence change ambient temperature block load on value was taken into analysis. further includes impact operation without high-pressure low-pressure heaters block. goal determine functional state individual after long period exploitation maintenance take appropriate measures improve their technical performance. Exergy during are largest boiler amount 313.42 MW, followed by turbine 205.60 condenser 1 6.03 2 5.75 while other have range 0.03 2.15 MW. Operation HPH results an decrease from 5.60 9.80 %, case LPH it 9.86 16.40 % depending pattern used calculate. conclusion indicates that biggest consequently these lowest values. increase has different effects plant, increasing reducing condensers.
