The high pressure, high temperature steam leaving the boiler expands in the turbine to produce shaft work. The steam leaving the turbine condenses into water in the condenser, rejecting heat and then water is pumped back to the boiler. Consider 1kg of saturated steam at pressure p. 1 and absolute temperature T 1, as represented by point 1. The

Why Multistage Pumps Are Best For Boiler Feed Applications

On the discharge side, the pressure generated from the pump must be enough to overcome the high pressure inside the boiler. All centrifugal pump curves show a decrease in pressure as flow increases. With single stage pumps, this means that a larger pump is needed to increase the pressure produced at a given flow rate.
