在2 MW热输入加压喷动流化床中试装置上进行了煤气化工艺及设备的可行性研究，并进行了长时间运行试验，研究了操作参数对煤部分气化行为的影响。试验结果表明，该气化炉为2G PFBC-CC下游系统提供合适的燃料气和残焦是可行的。随着气化温度的升高，甲烷的二次裂解导致甲烷浓度降低，而碳转化率增加，氢气浓度随蒸汽流量的增加而增加。主要实验结果与国际上的中试装置进行了比较。© 2005 ASME
Coal gasification process and equipment feasibility research were carried out in a 2 MW thermal input pressurized spout-fluid bed pilot-scale gasifier and a long-time-run test was performed to study the effects of operating parameters on coal partial gasification behaviors. The test results have demonstrated the feasibility of the gasifier to provide suitable fuel gas and residual char for downstream system of 2G PFBC-CC. The concentration of methane decreased at higher gasification temperature due to the secondary cracking of methane while the carbon conversion increased, and the concentration of hydrogen increased with an increase of steam flow rate. The main experimental results were compared with those of pilot-scale facilities in the world.© 2005 ASME
