摘要
国内引进的9FA燃气-蒸汽联合循环发电机组中,大多数是"一拖一"单轴机组(燃机、汽轮机、发电机同轴布置),"二拖一"多轴机组(燃机、汽轮机为分轴布置,各自带动发电机发电)在国内只有少数几套。"二拖一"机组在我国作为调峰机组使用,启停频繁,因此对其启动模式、启动过程中存在的一些问题及其对策和优化、以及启动过程的耗时和天然气耗量等进行讨论和阐述,具有一定的借鉴作用。
S209FA gas-steam combined cycle ＂Two-on-One＂ unit is arranged in multi-shaft.Steam turbine is started by IP cylinder.The start mode and progress are different with the single shaft unit.Through the introduction of start mode and start progress and the discussing of problem occurred during startup,the targeted optimized measures are brought up.We statistically analyze the time and gas consuming of the start progress as reference.
