Heat recovery, adsorption thermal storage, and heat pumping to augment gas-fired tumble dryer efficiency

•Energy storage, heat pumping, recirculation, and recuperation for gas-fired tumble dryers.•Energy savings from adsorption-based thermal storage and heat pumping investigated.•Recirculation and recuperation reduce energy consumption by 9% and 15%, respectively.•A 5-kg sorption bed results in energy consumption of 1.174 kWh kgw−1.•Integrating adsorption-based thermal storage system reduces energy consumption by 19%.
