Sufficient heat storage and proper flue-gas outlet temperature were prerequisites for selective non-catalytic reduction denitrification in coke oven regenerators. This work performed an energy balance analysis on the established regenerator model to obtain a new thermal storage evaluation index – total thermal storage temperature. Furthermore, ten cases of thermal storage parameters were set to analyze the effects of thermal effusivity and thermal diffusivity on heat storage and transfer. The transient simulation results shown that the channel shape of the lattice brick limited the uniformity of fluid-solid heat transfer and temperature distribution during the 30 minutes commutation period, and the temperature window (1100~1300 K) suitable for selective non-catalytic reduction denitration slowly moved down. The increase of thermal effusivity led to the rise of heat storage and reduction of flue-gas outlet temperature. However, the transform in thermal diffusivity did not contribute substantially to the heat storage performance. Besides, the temperature-time-height equation obtained by fitting was used for predicting the suitable location of selective non-catalytic reduction denitration temperature. The total thermal storage temperature was positively correlated with the flue-gas outlet temperature and negatively correlated with the heat storage capacity. The total thermal storage temperature evaluated the effects of material properties on heat storage and flue gas outlet temperature.
