摘要
为了考察神华煤作为航天炉干煤粉气化原料的适应性,系统分析了航天炉使用和试烧过煤种的煤质特点及气化特性,对航天炉适宜的原料煤特征进行归纳总结,以产自燕家塔、大柳塔和巴图塔的3种神华煤为研究对象,从工业分析和灰熔融特性的角度分别对其与航天炉原料煤的性质进行了对比分析,结果表明:航天炉粉煤加压气化技术对烟煤具有良好的适应性,对于高灰熔点的无烟煤,可以通过添加助剂或掺混煤的方式,实现稳定运行;3种神华煤具有高挥发分、高发热量、低灰低硫的烟煤特性,从工业分析特征来看符合航天炉用煤煤质要求,但从煤的灰熔融特性来看,产自大柳塔和巴图塔的神华灰熔点略低,需进一步通过掺混的方式,提高对航天炉的适应性。
In order to investigate the adaptability of dry pulverized gasification for Shenhua coal in HT-L gasifier,the quality characteristics and gasification characteristics of the coals used in HT-L gasifier are systematically analyzed and summarized.Taking three Shenhua coals from Yanjiata,Daliuta and Batuta as the research objects,the industrial analysis and ash melting characteristics of these coals are compared with the feed coals for HT-L gasifier.The results show that the bituminous coals are favorable used in HT-L Gasifier via the pressurized gasification technology of pulverized coal.The anthracite coal with high ash melting point can be used in HT-L Gasifier via adding fluxing agent or mixing other coal.The three kinds of Shenhua coals have the characteristics of bituminous coal with high volatile matter,high calorific value,low ash and low sulfur.Base on the industrial analysis,these Shenhua coals meet the coal quality requirements of HT-L Gasifier.However,the adaptability of the Shenhua coals from Daliuta and Batuta for HT-L gasifier need to be improved by mixing with other coal,for the reason that the ash melting points of these Shenhua coals are relatively lower.
