Using the following mass flow equation for saturated steam the pressure downstream of the surplussing valve (P2) can be calculated: In this example, at low fire, the boiler pressure is given as 12 bar g (13 bar a). It can be calculated from Equation 3.21.2 that the pressure after the fully open surplussing valve is 11.89 bar g (12.89 bar a).

Why We Run Steam Boilers At 2-PSIG Pressure -

Contractors had been using boiler pressure as a competitive edge. They were sizing systems with as much as 60-psi pressure at the radiators. Higher pressure means smaller radiators and pipes, but the problem is, all steam-heating systems have to start at 0-psi pressure, and at the lower pressure, the steam would suck the water out of the boiler.
