Meanwhile district heating systems are a powerful option to meet this demand with their significant potential and the experience accumulated over many years. The work described here deals with the conventional and advanced exergy performance assessments of the district heating system using four different waste heat sources by the exhaust gas potentials of the selected plants (munici-pal solid waste cogeneration thermal power wastewater treatment and cement production) with the real‐time data group based on numerical investigations. The simulated results based on conventional exergy analysis revealed that the priority should be given to heat exchanger (HE)‐I with ex-ergy efficiency values from 0.39 to 0.58 followed by HE‐II and the pump with those from 0.48 to 0.78 and from 0.81 to 0.82 respectively. On the other hand the simulated results based on advanced exergy analysis indicated that the exergy destruction was mostly avoidable for the pump (78.32– 78.56%) and mostly unavoidable for the heat exchangers (66.61–97.13%). Meanwhile the exergy destruction was determined to be mainly originated from the component itself (endogenous) for the pump (97.50–99.45%) and heat exchangers (69.80–91.97%). When the real‐time implementation was considered the functional exergy efficiency of the entire system was obtained to be linearly and inversely proportional to the pipeline length and the average ambient temperature respec-tively. © 2021 Elsevier B.V.
