| Abstract: | In order to investigate the characteristics of coal combustion at oxygen-enriched atmosphere higher than 40%,experiments were carried out in a 0.15 MW CFB combustion test system with a height of 6000 mm and a diameter of 140 mm.The results show that the coal could combust stably at O2/N2 atmosphere with the average oxygen concentration of 48.8%～52.3%.Coal combustion efficiency could reach 95.6%with the optimization of experiment parameters.The amount of circulation material is 404 kg/h and the circulation rate is 17.6. |
