摘要：以GE水煤浆气化炉为研究对象,在分析煤质组成中H/C比的基础上,利用C_(16)H1_0、C_(18)H_(30)和SO_2代替原煤,应用Aspen Dynamics建立水煤浆气化反应过程动态模型,动态模拟分析煤中不同H/C比等因素对气化过程的影响。模拟结果表明,在同等干煤负荷下,相比于煤中H/C比含量,煤中灰质含量对气化反应器温度、CO含量、冷煤气效率以及H_2S的影响较大,对H_2影响较小,对CH_4含量的影响基本不变。该研究结果为实际生产控制过程中的选煤、配煤等提供指导。
Through the study on hydrogen carbon ratio （H/C） in the coal quality composition, C16H10, C18H30 and SO2 were proposed to replace coal. A CWS gasification reaction dynamic model of General Electric （GE） coal-water slurry （CWS） gasifier was built to dynamically simulate the effects of coal quality with different H/C ratio on CWS gasification process by using Aspen Dynamics software. The simulation results showed that the slag of coal is with larger influence on the temperature of gasification reactor, CO mole fraction, cold gas efficiency and H2S content than different H/C ratio of the coal under the same condition of coal feed. While it is with smaller influence on HE mole fraction and it almost no effect on CH4 mole fraction. The results of the paper can provide guidance for coal selection and matching during the actual production process.
