Correct Max pressure for a steam boiler? - DoItYourself ...

Nov 21 2010 · ALL residential steam boilers have a Maximum Allowable Working Pressure (MAWP) of 15 psi. Either you read the gauge incorrectly or the gauge is nothing but a paperweight attached to the boiler. Most residential heat systems work well with less than 2 psi and some work well with 1/2 psi...or at least as well as a residential system can.

High Pressure Boiler: What is it? Types & Characteristics

The pressure and steam of a high pressure boiler is produced by burning a fuel such as coal natural gas or petroleum. The heated gases from the burning fuel are circulated by natural convection or forced by a pump. Forced circulation is produced by a centrifugal pump to increase the evaporation rate to 210 k of force per square centimeter.
