摘要:
介绍了煤气化工艺优劣的评价方法，指出以效率代替热效率和气化效率评价型煤移动床富氧连续气化更全面、准确.以型煤移动床富氧连续气化，代替间歇移动床煤气化，达到节能减排目的.采用热力学分析方法，对气化系统进行了量衡算，分析了型煤移动床富氧连续气化的效率和损失状况，探讨了提高气化系统利用率的措施.结果表明：气化炉是损失最大的设备，占总损失的79.3%；夹套锅炉效率最低，仅为29.8％；而洗涤冷却塔是热损失最大的设备，带走大量低位能热，占系统总输入热的12％.气化效率为67.8％，高于水煤浆气流床气化效率.型煤移动床富氧连续气化技术效果较好，具有良好发展前景.
Abstract:
Evaluation methods of coal gasification were introuduced. Using exergy efficiency analysis method is more comprehensive and accurate than heat or gasification efficiency in the evealuation of moving bed continuous gasification of briquette with oxygenrich air，which is savingenergy and cleaning production process, instead of intermittent moving bed coal gasification. Exergy thermodynamic analysis method was used to calculate energy balance, analyze the exergy efficiency and loss, and discuss how to raise exergy efficiency for this oxygenenriched continuous gasification of briquette moving bed. The results were shown as follows：1.Gasification furnace with the maximal exergy loss accounted for 79.3% of total exergy. 2.Exergy efficiency of Jacket boiler,29.8%, was the lowest. 3.Scrubbingcooling column was the maximum heat loss which occupied 12% of total heat. 4.Exergy efficiency of gasification process system，which was higher than quenching entrainedflow coal gasification, reasched 67.8%. Oxygenenriched continuous gasification of briquette moving bed is a promising coal gasification technique due to the higher gasification efficiency.
