Title
(KO) 보일러 플랜트의 세정 보관 방법 및 세정 보관 장치
Abstract
(KO)
화학 세정으로부터 통상 운전을 개시할 때까지의 기간에, 저비용 또한 단시간에 보일러의 세정 대상 부위의 방청 처리를 행하고, 보일러를 보관할 수 있는 보일러 플랜트의 세정 보관 방법 및 세정 보관 장치를 제공하는 것을 목적으로 한다. 본 개시의 보일러 플랜트의 보관 방법은, 스케일이 부착된 세정 대상 부위를, 제청제를 포함하는 중성의 세정액에 의해 상온에서 중성 세정하는 공정(S2)과, 세정 대상 부위에, 암모니아계 화합물을 포함하는 pH 9.8 이상의 상온의 암모니아계 화합물 수용액을 순환시키는 공정(S4)과, 세정 대상 부위로부터, 암모니아계 화합물 수용액을 블로우하는 공정(S5)을 구비하고 있다.
