Boiler feed pump KSB

Nowadays, almost all boiler feed pumps must be able to handle both cold starts (high-temperature shock loads) and semi-warm starts without any damage. In these start-up procedures hot feed water abruptly flows into the cold pump, which results in the inner components heating up much faster than the pressure boundary.

Two Aspects of Deciding Between A Ring-Section and A Barrel Pull-Out Pump Are Described Below1. The smaller the mass flow rate and the higher the pressure, the higher the material and manufacturing costs of barrel pull-out pumps. This does.Tapping A Stage of A Boiler Feed Pump1. In the case of ring-section pumps, a partial flow at an intermediate pressure can easily be tapped through a tapping nozzle in one of the stage.Balancing of Radial Forces on The Pump RotorRadial forces arise from the weight of the rotor, mechanical unbalance or hydraulic radial thrust. The radial forces are balanced by two oil-lubric.Warming Up and Keeping WarmTransient or low flow operating conditions cause additional loads on boiler feed pumps.

Boiler Feed Water Pump Working Principle and Operation

Boiler feed water pumps are commonly centrifugal pumps. To ensure a high enough head and pressure, Boiler feed Pumps have been arranged in series (multistage pumps). A feedwater pump is most often driven by an electric motor for energy efficiency. Often two steam turbine-driven (turbo pump) and two electric feedwater pumps are used.
