Understanding Boiler Pressure | Boiler

As an industry standard and due to safety concerns and materials used, all cast iron boilers are made with an MAWP of 15 PSI steam, which makes them all defined as low pressure boilers. With every boiler, it's good practice to make sure that the ratings of the manufacturer's MAWP stamp match or exceeds the safety valve ratings.

Boiler Feedwater - an overview | ScienceDirect Topics

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
