Aplication Of Combined Exergy And Pinch Analysis For Khartoum North Power Station Phase (2)

Abstract

In this research,Khartoum North Power Station Phase (2)has been discussed in accordance with Exergy and Pinch technology analysis.Exergy analysis is introduced and defined as energy quality analysis. Also exergy is work potential of energy. The main parameters of exergy analysis has been considered in this research is exergy, exergydestruction(irreversibilities) and second-law efficiency.As outcomes of exergy analysis discussion, the full power plant performance definition is to specify actual work, irreversibility and second-law efficiency which is founded in KNPSP(2) 60 MW,131.3 MW and 31.4% respectively. Also, the worst components in the plant needs to redesign and re-evaluation are first and second feed water heat exchanger according to exergyanalysis. For efficiency of regenerative feed water heat exchanger, the net workincludes heat exchangers from first to fourth is inefficient and needs to redesign but the other net work includes fifth and sixth heat exchangers is efficient heat exchange network.
