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 steam being generated.

In order to prevent foaming and carryover, the build-up of the boiler TDS needs to be controlled by removing concentrated boiler water via blowdown and replacing it with fresh feed water with a lower TDS. The guidance in BS2486 indicates that for most shell boilers that the TDS should be limited to a maximum 3500mg/l.
