| 摘 要： | 在构建的热输入2MW的中试规模加压喷动流化床部分气化试验装置上,对徐州烟煤的加压部分气化行为进行了研究.重点考察了气化温度对煤气成分、煤气热值、碳转化率和煤气产率等气化指标的影响.研究结果表明,煤气各组分的浓度,特别是甲烷浓度对气化温度非常敏感,碳转化率和煤气产率随温度的升高而增加,在试验的温度区间内,温度对煤气热值影响不大.部分气化炉所产生的煤气和半焦的热值均满足第二代增压流化床联合循环发电系统的要求.

| Abstract: | Experimental research on partial gasification of Xuzhou bituminous coal was carried out in a 2 MW thermal input pilot-scale pressurized spout-fluid bed gasifier.The study focused on the influence of gasfication temperature on gas compos- tions,gas beating value,carbon conversion and gas yield.The results indicate that the gas compositions,especially for meth- ane,are sensitive to gasification temperature.Carbon conversion and gas yield increase with the rise of temperature,while the gas heating value is independent of the temperature in the range of experimental temperature.The heating values of fuel gas and char residue can meet the second generation pressurized fluidized bed combustion combined cycle(2G PFBC-CC). |
