摘要
以9FA燃气轮机配套的余热锅炉为例,介绍了F级余热锅炉特点及蒸汽减温配置,主蒸汽温度、二级高压过热器出口温度及再热蒸汽温度的控制策略,过热度保护和最小流量保护的实现方法。机组启动阶段,IGV参与燃气轮机排气温度控制,此时采用IGV角度前馈来稳定启动期间的主蒸汽温度。
Based on heat recovery steam generator which form a complete set for 9FA gas turbine, this paper introduces the characteristic and steam attemperator arrangements of F class heat recovery steam generator, the gas turbine and steam turbine combined cycle steam control strategy of main steam, HP II superheater outlet steam and reheat steam; also introduces implementation method of superheat protection and minimum flow protection. Inlet guide vane participate in temperature control of gas turhinc exhaust during unit start up, to stabilize main steam temperature, utilizing inlet guide vane angle feedforward.
