Abstract
A chemical solution injection systemof an embodiment includes: a chemical solution reservoirthat stores a chemical solution containing a depositing substance to deposit to a member in contact with cooling water for absorbing heat in a plant; a pipethrough which the chemical solution passes; a first heat exchanger and a second heat exchanger that exchange heat between the cooling water and the chemical solution; a cooling water pipewhich connects the heat exchangers in series and in which the cooling water passes; and a pumpthat conveys the chemical solution. The temperature of the chemical solution in the chemical solution reservoiris lower than that of the cooling water. The pipesequentially connects the chemical solution reservoir, the first heat exchanger, the second heat exchanger and the plant. The cooling water guided from the inside of the plant passes through the second heat exchanger and subsequently passes through the first heat exchanger. The chemical solution passes through the first heat exchanger and subsequently passes through the second heat exchanger.
