Beschreibung
Zusammenfassung:	The utility model discloses an energy-saving gas turbine NOx emission reduction system which comprises a water cooling tower, a multi-stage air supply system and an SCR (Selective Catalytic Reduction)system, by adjusting the mixing proportion of air heated and humidified in the water cooling tower and air outside the tower, the humidity and the temperature of the introduced air are controlled, and the air and the filtered gas are mixed and enter a combustion chamber to reduce the NOx emission concentration; and the energy consumption and material consumption of the SCR system are reduced. 本实用新型公开了一种节能型燃机NOx减排系统，该减排系统包括水冷塔、多级送风系统和SCR系统，通过调节水冷塔中加热加湿的空气与塔外空气混合比例，控制通入空气的湿度和温度，与过滤后的燃气混合进入燃烧室降低NOx排放浓度，并减少SCR系统的能耗与物耗。
