%X The characteristics of sulfur release during HT-coal combustion in the mixed-CO_2 gas with different concentrations of oxygen were studied. The results show that during combustion in low oxygen concentration flow the rate curves of H_2S and SO_2 present two clear peaks, the quantity of released H_2S increases and the whole time of sulfur release is prolonged. On the contrary, during combustion in high oxygen concentration flow the rate curves of H_2S and SO_2 show single peak, the time of sulfur release shortens. Because of improvement of self-capturing sulfur ability of the ash, the quantity of sulfur release is reduced during combustion in the mixed-CO_2 gas with low oxygen concentration. The quantity of sulfur release from coal burned in high oxygen concentration flow is close to that burned in the air flow.
