Résumé
This study elaborates the incorporation of thermally-driven absorption heat pumps (AbHP) in industrial dryers for waste heat recovery purposes. The waste heat stream – hot humid air that would otherwise be rejected – provides to the desorber heat, which is returned multiplied at the absorber and condenser, where it preheats the inlet air of the dryer’s gas-heater. In some cases, the cooling produced at the evaporator is utilized for partial condensation of the rejected humidity, providing also water savings. Initially, an analysis was conducted regarding the simpler choice of employing air-to-air heat exchangers. Subsequently, various scenarios with AbHP were studied in steady state. Finally, the two most promising scenarios were studied for the entire transient process. The first case provides energy savings of 29.7%, with electricity consumption of 115.6 kWther/kWelec. The second provides energy savings and electricity consumption of 36.3% and 15.7 kWtherl/kWelec, respectively, while 14% of water savings is also achieved.
