Beschreibung
Zusammenfassung:	The invention discloses an NOx emission reduction system and method of an energy-saving gas turbine. The emission reduction system comprises a water-cooling tower, a multistage air supply system and an SCR system. Through regulation of the mixing proportion of heated and humidified air in the water-cooling tower to air outside the tower, the humidity and temperature of introduced air are controlled, and mixed with filtered gas to enter a combustion chamber so that the NOx emission concentration is reduced; and the energy consumption and material consumption of the SCR system are reduced. 本发明公开了一种节能型燃机NO减排系统及减排方法，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NO排放浓度，并减少SCR系统的能耗与物耗。
