LOCALIZATION OF EXERGY LOSSES IN THE HEAT RECOVERY SYSTEMS OF BOILER PLANTS

The results of the analysis of the localization of exergy losses in the heat recovery systems of boiler plants during the implementation of methods of anti-corrosion protection of gas exhaust tracts are presented. The methods are aimed at increasing the temperature and reducing the relative humidity of the flue gases entering the exhaust ducts. a complex methodology based on a combination of balance methods of exergy analysis and structural-variant methods was used for the study, he technique makes it possible to develop block diagrams for heat recovery systems in which anti-corrosion protection methods are implemented, and to establish the locations of exergy losses. Structural diagrams of the main elements of a boiler plant with heat recovery systems in the implementation of anti-corrosion protection methods are presented. On the basis of block diagrams, the main places of localization of exergy losses are determined and exergy balance equations are obtained for calculating exergy losses in places of localization.
