Description
(始動動作)
従来のCC発電システムにおける始動プロセス時、ガスタービンは、より低負荷(例えば、最小排出適合負荷(MECL)と比べて)に留まる必要があり、その結果、より高濃度のNOx及びCO排出物がもたらされる。これは、例えば、蒸気タービンに流入する蒸気の温度を約700°Fに維持して蒸気タービンにおける熱応力を回避するために行われる。この低負荷は、図4においてポイント「A」で示される。
(通常動作)
通常動作時、ファン56によって供給されてガスタービンシステム12の排気ガス流32に混合される周囲空気は、HRSGシステム130への流れを増大させかつ流れの温度を下げる。このことは、HRSGシステム130の管温度限界(例えば約1600°F)に達することなくダクトバーナシステム142における高いファイアリングを可能にする。これはまた、CC発電システム110のボトミングサイクルからの出力を高めることも可能にする。実施形態において、CC発電システム110の出力は、従来のCC発電システム(すなわちファン56なし)の出力と比べて例えば10%から15%高めることができる。
1)ファン56の回転状態、
2)排気ガス流32を冷却するために混合領域36に供給される周囲空気の量、
3)ダクトバーナシステム142のファイアリングの量(例えば、周囲空気が排気ガス流32に注入された後に排気ガス流の温度を目標レベルまで動かすため)、及び
4)ガスタービンシステム12のオーバーファイアリング又はアンダーファイアリングの量(トッピングサイクルにおいて実現可能な限り多くのエネルギーを提供するため)
