The aim is to understand the thermal storage characteristics of porous media thermal storage materials under thermal dynamic conditions, and obtain the dynamic thermal storage characteristics parameters of thermal storage materials. In the 120 kW thermal dynamic thermal storage system of porous media, we studied the dynamic thermal storage characteristics of honeycomb porous ceramic thermal storage materials with different pore diameters (2.9, 4, 5.5 mm) and lengths (100–400 mm) under different hot flue gas conditions include thermal storage rate, thermal storage efficiency and storage. The results show that the relationship between the heat storage rate and time is parabolic, and the heat storage efficiency gradually decreases with the heat storage time. At the same time, the regenerative rate and unit regenerative resistance loss increase with the increase of specific surface area or the decrease of pore diameter of regenerator, and the regenerative efficiency increases with the increase of regenerator length. According to the experimental research and analysis, the dynamic heat storage characteristics of porous regenerator can be characterized by heat storage rate, heat storage efficiency and unit heat storage resistance loss.

Ceramic heat exchangers are preferred in most high temperature applications due to its high temperature stability and corrosion resistance. This work investigated the performance of a ceramic heat exchanger, evaluating the heat transfer and pressure drop theoretically by Ɛ-NTU method by using silicon carbide and aluminium nitride as heat exchanger material. The performances of both the heat exchangers are correlated. The heat exchanger of cross flow type considered for this study entails of rectangular ducts for the passage of exhaust gas, a ceramic core, and the air passage through rectangular ducts. The heat exchangers were studied using conventional Ɛ-NTU method with numerous Nusselt analogies to characterize the flow in the rectangular duct. The theoretical analyses reveal that, the performance parameters such as overall heat transfer increased by 4.5-5%, effectiveness by 3% and heat transfer rate by 3% using aluminium nitride as the heat exchanger material relative to silicon carbide.
