摘　　要：以福建无烟粉煤和粘结剂成型制得型煤,用富氧空气为气化剂,在3 m型煤移动床富氧连续气化炉上进行了工业化气化试验。结果表明,型煤移动床富氧连续气化,可以实现安全稳定可靠气化运行,制出合格半水煤气,气质能满足合成氨、甲醇生产,可代替间歇式移动床气化。气化火用效率为67.2%,气化效果较好,有显著的节能减排效益,良好的推广应用前景。但有效气体成分偏低,CO2含量比较高。可采用高活性的晋城无烟粉煤生产的型煤气化或通过添加剂提高煤灰熔融温度、气化温度等措施,降低煤气中CO2含量。Fujian anthracite and binder are mixed to prepare briquette.Taking oxygenated air as gasification agent,carry out industrialize briquette continuous gasification experiments in moving-bed oxygenated gasifier,whose diameter are three meters.The results show that this continuous gasification could guarantee the safety and stability of system,the properties of semi-watergas could meet the demand of synthetic ammonia and methanol production.That means the new gasification technology can replace moving-bed gasification.The gasification exergy efficiency is 67.2 percent.The results show that the gasification effect is better,also has wide application and dissemination prospect.However,the needed gas is low,while CO2 content is high.Those problems can be resolved by adding additive to mixture,which would raise melting and gasification temperature of coal ash,or taking high activity Jincheng anthracite to prepare briquette.
