Exergy destruction calculation and analysis for a Coal drying system

open access: yesIOP Conference Series: Earth and Environmental Science, 2020
Abstract A coal drying system was modelled and the calculation methodology was developed to calculate the system. Then the system performance was obtained and the exergy destruction and loss in the system is 70.5 kW. The reasons of exergy destruction were tried to be explained from the perspective of energy grade.

Cost Analysis and Optimization of Green Hydrogen Production via Concentrating Solar Technologies and PEM Electrolyzer

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
The burgeoning demand for power across the globe and the disastrous effect of climate change that results from power generation through depleting unclean fuel sources have necessitated the use of renewable and clean fuels. Hydrogen is a good alternative but only when produced from low‐carbon energy resources.

"Visualizing the exergy destructed in exergy delivery chain in relation to human thermal comfort with ExFlow"

open access: yesHealthy, Intelligent and Resilient Buildings and Urban Environments, 2018
Exergy analysis is an important tool to fully appreciate the usability of energy at different levels and has been widely applied in the building system analysis domain. It has became more useful as low temperature heating and high temperature cooling began to attract more attention both in Europe and the United States.
