The synthesizing and refining methods of polyether amine gas lustration lotion and its performances of antirust and lustration are introduced. The experiment shows that polyether amine gas lustration lotion not only has the outstanding lustration performances for intake values and does not increase the production amount of CCD in firebox, but also restrains the production of sediments in the firebox effectively by mixing the mannich lustration lotion with carrying lotions of polyether polyol, polyether amine, and amide alkanolamine.
