RESEARCH OF EXERGETIC LOSSES IN HEAT TRANSFER PROCESSES FOR LAMELLAR AND SMOOTH TUBE AIR HEATING HEAT RECOVERERS

The study results of local exergetic losses in heat transfer processes for lamellar and smooth-tube air-heating heat recovers of boiler plants at different values of technological parameters are presented. It is established that for increase of exergy efficiency of heat recovery systems it is necessary to reduce exergy losses at heat transfer from a wall to air and to use lamellar heat-recovery units as much as possible.
