摘要
成本过高和可靠性较低是制约整体煤气化联合循环整体煤气化联合循环商业化的重要因素.从系统方面对不同配置的整体煤气化联合循环进行了可靠性建模与分析,并对单列整体煤气化联合循环系统进行了可靠性设计.结果表明:当前单列整体煤气化联合循环系统的可用度只有70%左右,采用多列耦合或备用气化炉能够大幅度提高整体煤气化联合循环系统可用度;要使单列整体煤气化联合循环可用度不低于90%,要求气化炉可用度高于94%,燃气轮机可用度高于97%,余热锅炉的可用度也需要较大幅度的提高.
commercla High lization configuration the capital cost and low reliability are of two factors which seriously restraint the of integrated gasifi reliability model is cation combined cycle （IGCC）. Based on IGCC systems of different established and then IGCC system is completed. Currently the reliability of redundancy gasifier or several IGCC coupled trains can necessary to improve the availability of gasifier higher th analy singl zed. The reliability design for e train IGCC is only about greatly enhance the an 94%, availability single train 70%, using availability of IGCC. It is of gas turbine higher than 97% to enhance the availability of single train IGCC system to 90%.
