Boiler Feed Water Treatment; pH Control. Is yours correct?
WebbBy regulating the neutralizing amine feed rate, the condensate pH can be elevated to within a desired range (e.g., 8.8-9.2 for a mixed copper-iron condensate system). Many amines are used for condensate acid neutralization and pH elevation. WebbBoiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have … phishing definice
