    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). Consequently, the pressure drop is small (0.11 bar) and would not be significant in …Get Price
