本文对采用西门子燃气轮机的政州IGCC电厂作了简短概述。着重讨论了BuggenumIGCC电厂在示范运行阶段的运行经验。从1994年4月以来，一台燃烧和燃料系统经过改进的V94．2燃机已累计运行了几千小时，并且为西门子合成气燃烧系统提供了首次现场经验．完全整体化的电厂（10％气化空气抽自压气机出口）和各种不同的运行要求需要燃气轮机具有很高的灵活性。对燃用常规（备用）燃料、中热值和低热值煤气的所有正常和紧急负荷工况都进行了成功的试验． This article gives a brief overview of the state IGCC power plant with Siemens gas turbines. It focuses on the operational experience of the BuggenumIGCC power plant during the demonstration phase. Since April 1994, a V94.2 gas turbine with a modified combustion and fuel system has been operating for thousands of hours and has provided its first field experience in Syngas combustion systems. A fully integrated power plant (10% gasified air drawn from the compressor exit) and a variety of different operating requirements require gas turbines with great flexibility. Successful tests have been conducted on all normal and emergency load cases using conventional (standby) fuel, medium and low calorific gas.
