A novel district heating system based on absorption heat exchange and water-heat combined supply

Case Studies in Thermal Engineering, 2023
Considering the challenges posed by long transportation distances and poor heating economy in large-scale heating systems based on conventional steam extraction cogeneration in nuclear power plants, a novel district heating system is proposed. This novel system is based on absorption heat exchange and water-heat combined supply.

Combined optimization for retrofitting of heat recovery and thermal energy supply in industrial systems

Applied Energy, 2022
Abstract Predicting the outcome of possible changes in interlinked industrial energy systems is hard, especially in retrofit scenarios. This leads to severe uncertainties when making investment decisions. In this paper, a new combined optimization approach is presented that aims to support decision-making in these cases. Our approach links models for
