Gas Turbine Inlet Air Cooling 燃气轮机进气冷却 Optimize Efficiency & Maximize Power 优化效率 & 增加发电
Agenda
目录
• GTIAC System Optimization (early phase consideration)
Cold Weather 冷天
Hot Weather 热天
Inlet Air Properties 15°C DB; RH 60% Density: 1.22 kg/m3
Inlet Air Properties 45°C DB; RH 30% Density: 1.098 kg/m3
10%
Mass Flow Reduction
燃机进气冷却GTIAC系统对燃机电厂性能的优化（前期规划设计阶段）
• Gas Turbine Inlet Air Cooling Concept
燃气轮机进气冷却原理
• Major GTIAC Technology options
燃气电厂进气冷却主流技术
• Mechanical GTIAC System
during the design stage.
许多新建的发电厂在设计阶段并没有将GTIAC系统考虑进去。
GTIAC VS 新建装机 发电出力对比
• Increase power output 提升燃机发电出力
• Lower $/kW compare to new turbine 降低燃机初投资成本
业主投资方一般考虑的重点因素包括以下：
单位千瓦造价
Combine cycle
spec of HRSG
电厂技术路线， 如余热锅炉蒸汽 压力等匹配优化

压气机进气温度升高，空气密度降低。
• Lower air density reduces the mass flow entering the GT and therefore reduces the power output of the GT.
空气密度降低会减小进入燃气轮机的空气质量流量，减小其出力与发电量。

Gas Turbine Inlet Air Cooling Concept
燃气轮机进气冷却原理
• Gas Turbines (GT) are constant volume machines.
燃气轮机进气体积恒定。
• As the temperature of the air entering the compressor increases, the density of the air decreases.
2. Heat Transfer process between coils and ambient air removes sensible and latent heat from ambient air 冷却盘管带走空气中的显热及潜热
3. Resulting air is cooled to design inlet temperature to turbine 空气被冷却到设计温度，如15℃ 4. Chilled air is ingested into the compressor of the turbine 冷却后的空气进入压气机
