| 摘 要： | 以空气和水蒸气为气化剂,在循环流化床煤气化热态试验台上进行了神华、龙口和大同煤的气化试验,研究了蒸汽煤比和煤种对气化过程的影响。试验结果表明:随着蒸汽加入量的增加,床温和煤气热值下降,碳转化率基本保持不变,冷煤气效率基本保持不变或略有下降;龙口煤在加煤速率为10.08kg/h时取得了最高的冷煤气效率值53.96%,而神华煤在加煤速率为6.4kg/h时取得了最高的冷煤气效率值43.98%;煤的活性越高,可以取得的煤气化效率越高,煤气化炉的处理能力也越大。

| Abstract: | The gasification experiments of Shenhua,Datong and Longko coal with the agents of air and steam at atmospheric pressure were made on a circulating fluidized bed gasification test rig.The effects of steam/coal ratio and type of coal on gasification process were studied.The results show that with the increase of steam/coal ratio,the temperature of lift and the heating value of product gas decrease,the conversion and efficiency maintain or fall appreciably;in the investigated range,the maxmal gasification efficiency could be obtained 53.96% at the feed rate of 10.08kg/h for Longko coal and 43.98% at the feed rate of 6.4kg/h for Shenhua coal,respectively;the more active coal is,the higher efficiency and capacity will be obtained. |
