Why you can't use high-pressure steam boilers on low-pressure

Jun 23, 2014 · This is why you can't run a high-pressure boiler on low-pressure settings. The boiler manufacturer told the contractor about this when the contractor called to ask. The contractor thought he could get around the high-velocity problem by cutting into the boiler and welding a bigger nozzle onto the shell. The boiler manufacturer said this would probably work, but the contractor hadn't mentioned the pipes.
