Boiler Feedwater - an overview | ScienceDirect Topi

Boiler 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 been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of
