The present invention provides a compressor washing apparatus and a gas turbine including the same. The compressor washing apparatus comprises: a steam generator installed in front of a compressor of a gas turbine and generating steam; a steam header installed behind the steam generator and storing the steam generated from the steam generator therein; a first injection pipe and a second injection pipe connected to the rear of the steam header and selectively supplying the steam from the steam header to the compressor; a water supply means for supplying water to the first injection pipe and the second injection pipe, respectively; and a first injection nozzle and a second injection nozzle which are installed at an inlet of the compressor, receive the steam or the water from the first injection pipe and the second injection pipe, respectively, and spray the steam or the water to a compressor vane and a compressor blade inside the compressor. Each of the first injection nozzle and the second injection nozzle includes an injection body and a nozzle means rotatably installed on the injection body and spraying the supplied steam or water into the compressor. The present invention allows the compressor to be washed smoothly without problems even in the winter. 본 발명은, 가스터빈의 압축기 전방에 설치되며, 증기를 발생시키는 증기발생기; 상기 증기발생기의 후방에 설치되며, 상기 증기발생기에서 발생된 증기가 내부에 저장되는 증기헤더; 상기 증기헤더의 후방에 연결되며, 상기 증기헤더로부터 상기 압축기로 증기를 선택적으로 공급하는 제1분사배관 및 제2분사배관; 상기 제1분사배관과 제2분사배관으로 각각 물을 공급하는 급수수단; 및 상기 압축기의 입구에 설치되며, 상기 제1분사배관과 제2분사배관으로부터 각각 증기 또는 물을 공급받고, 상기 압축기의 압축기 베인 및 압축기 블레이드로 증기 또는 물을 분사하는 제1분사노즐 및 제2분사노즐을 포함하되, 상기 제1분사노즐과 제2분사노즐은, 각각, 분사본체와, 상기 분사본체에 회전 가능하게 설치되며, 공급받은 증기 또는 물을 상기 압축기의 내부로 분사하는 노즐수단을 포함하는 압축기 세정장치 및 이를 포함하는 가스터빈을 제공한다.
