IGCC燃气轮机二次风阀控制优化

Control Optimization of IGCC Gas Turbine Secondary Air Valve

天津IGCC电站是国内第一座IGCC电站,文中介绍了IGCC示范工程概况,详细描述了燃气轮机(简称燃机)二次风阀的动作原理和重要作用。针对二次风阀的现状,分析了反馈改造和控制优化的重要性,提出了改造实施方案,通过改造实际运行表明:改造方案提高了设备可靠性,消除了因设备故障导致机组非计划停机的风险。

The general situation of the first IGCC demonstration project in China is introduced,and the action principle and important role of the secondary air valve of gas turbine(gas turbine for short)are described in detail.According to the current situation of the secondary air valve,the importance of feedback transformation and control optimization is analyzed,and the transformation implementation scheme is put forward.The actual operation of the transformation shows that the transformation scheme improves the reliability of the equipment and eliminates the risk of unscheduled shutdown of the unit caused by equipment failure.
