摘要: 目前碎煤加压气化技术存在着一定的问题,主要是副产物多、气化废水量大和气化废水难处理等问题,这些问题的存在已经限制了碎煤加压气化技术的应用。为了解决这些问题,在仔细分析了加压固定床的气化原理后,从根本上找出产生问题的原因在于选用了不适合的气化煤种,并提出了碎煤加压气化技术对原料煤质的要求。在通过褐煤、长焰煤、贫瘦煤、无烟煤的煤质分析进行分析后,提出了无烟煤是碎煤加压气化技术最适合的煤种,又结合已经在碎煤加压气化炉上使用的褐煤、长焰煤、贫瘦煤、无烟煤的主要工业运行参数进行了分析对比,进一步确定了无烟煤是碎煤加压气化技术的最适合的气化原料煤。同时实际的工业运行结果也说明:在碎煤加压气化炉上使用无烟煤,可以从根本上降低气化废水的处理量和处理难度。

关键词: 碎煤加压炉, 煤质分析, 气化废水, 无烟煤

Abstract: At present,there are some problems with crushed coal pressurized gasification technology,such as more byproduct,more gasification wastewater and more refractory gasification wastewater and so on,which have restricted the application of crushed coal pressurized gasification technology.In order to solve these problems,after carefully analyzing the principle of pressurized fixed bed gasification,find out that it is not choosing the suitable gasification coaland put forward the requirements of raw coal that is fit for crushed coal pressurized gasification technology.By analyzing the coal analysis of lignite,long flame coal,lean coal,anthracite,propose that the anthracite is the most suitable types of crushed coal pressurized gasification technology.At the same time,combined with the main industrial operation parameters of the lignite,long flame coal,lean coal and anthracite,further verify that the anthracite coal is most suitable for coal gasification technology and the actual industrial operation result shows that using the anthracite can radically reduce the amount of gasification wastewater and the disposed difficulty.

Key words: crushed coal pressurized gasifier, coal analysis, gasification wastewater, anthracite
