摘　　要：介绍了气流床气化对煤质的要求,论述了煤的水分、反应活性、粒度和灰分对气化的影响。研究表明,煤的内水含量是决定煤浆性能的主要因素,灰渣的黏温曲线比灰熔点对气化炉的操作更具指导意义,选择在操作温度区间灰渣黏度变化平缓的煤种有利于气化炉的安全、平稳运行。The requirement of gasification with gas flow bed on coal quality was introduced,the influence of coal moisture,reactivity,size and ash on gasification was described.The study showed that water in coal was the main factor to determine coal slurry property,the sticking temperature curve of ash slag had more instructive significance than ash fusion point in the operation of gasifier,to select coal which had flat ash slag viscosity variation in the operating temperature area was beneficial to the safe and stable running of gasifier.
