Summary: The hydrodynamic and thermochemical characteristics in the coal-direct chemical looping combustion (CLC) process were studied using a self-developed computational fluid dynamics - discrete element method (CFD-DEM) approach. The results showed that increasing the coal feeding rate improved the combustion efficiency, while finer oxygen carriers promoted the conversion of gas products. In addition, a dual-side coal feeding arrangement significantly improved the system's uniformity.

Summary: This study investigates a novel system that integrates Chemical Looping Electricity Storage (CLES) system with Pumped Thermal Energy Storage (PTES) system and develops thermodynamic models considering the temperature difference between charge and discharge. The results show that the existence of temperature difference reduces system round-trip efficiency, and the variation in discharge temperature has a more significant impact. The system round-trip efficiency can be improved by adopting a turbomachine with high isentropic efficiency, reducing pressure loss, and optimizing the temperature ratio.

Summary: This paper proposes and studies a piston-type thermally-driven pump with a structure similar to a linear compressor, aiming to eliminate the high-quality energy consumption of existing pumps and replace mechanical pumps. The coupling mechanism of working fluid flow and element dimension is analyzed based on force analysis, and experimental data analysis is used to determine the pump operation stroke. Theoretical simulation is conducted to analyze the correlation mechanism of the piston assembly. The research shows that the thermally-driven pump can greatly reduce power consumption and has potential for industrial applications.
