STUDY OF THE EXERGIC EFFICIENCY OF HEAT RECYCLING SYSTEMS FOR VARIOUS PURPOSE

The paper presents the results of a comparative analysis of the exergy efficiency of heat recovery systems for various purposes for boiler plants. To study the exergy efficiency of heat recovery systems, a complex methodology was used based on exergy analysis methods and the application of efficiency assessment criteria. Heat recovery systems for various purposes are presented in the form of block diagrams with identification of exergy flows of coolants. Criteria for assessing exergy efficiency were selected, on the basis of which a comparative analysis of the exergy efficiency of heat recovery systems was carried out. Recommendations have been developed for the use of heat recovery systems for various purposes, taking into account the specifics of their application.
