During oxy-fuel combustion, pulverized coal combustion occurs in the presence of elevated CO₂ level because of flue gas recirculation (FGR). Recent experimental and computational investigations about oxy-coal combustion have suggested that char-CO₂ gasification rates are sufficiently high under oxy-fuel combustion conditions to significantly influence the char combustion process. However, experimental measurements of such rates and its kinetic data under the relevant high temperature conditions (T > 1700 K, 1 atm) are lacking and this makes it difficult to predict the effect of CO₂ gasification reaction on the overall char consumption rate. To address this, we have measured both the char particle temperature size and velocity statistics and the char mass loss when two U.S. coal chars(a bittuminous and a subbituminous) are introduced into a high-temperature optical flow reactor with nearly 100% CO₂. The experimental measurements show a temperature decrease from the gasifying particles (consistent with the strong endothermicity of the char gasification reaction) and show increasing mass loss with increasing residence time and temperature, as expected. The overall gasification rate and rate coefficient are derived from the measured data and compared with the literature data.
