摘要
The thermogravimetric analyzer and flue gas analyzer were utilized to investigate the co-combustion behaviors and gas pollutant emissions of coal slime (CS) and moso bamboo (MB) mixtures in O2/CO2 atmospheres. Principal component analysis was employed to ascertain the contribution rate and identify the primary reactions of CS and MB combustion. Four kinetic methods were applied to calculate the apparent activation energy (E alpha) and the most probabilistic mechanism function. The data exhibited that higher oxygen concentrations could promote combustion, and adding MB to CS further improved combustion performance. Co-combustion of CS and MB effectively inhibited total SO2 and NOx emissions; specifically, the NOx conversion rate was lower than that observed in air, whereas the SO2 conversion rate exceeded that found in air. The contribution rate of two major components to the total variance was 99.35%. A blending ratio of 50% MB is recommended owing to the stronger synergistic promotion and lower E alpha. Furthermore, the most probable mechanism function for CS was g(alpha) = 1 - (1 - alpha)1/4; the mechanism was reaction order. The E alpha prediction model of CS and MB co-combustion under oxy-fuel conditions was established using artificial neural networks.
