Normal operating pressure for Burnham gas boiler

Dec 02, 2014 · I filled the water pressure to about 12/13 psi when the boiler was cold. After turning on the heat, the water pressure increased to about 20 psi and stayed there during the 3 hours of heating. The water temperature increased to about 160-180 degrees. 1. Is 20 psi a normal operating pressure for residential boilers?

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
