Boiler and Feedwater Pump Efficiency Optimization ...

In electrical power plants demineralized feedwater is pumped to the boiler tube header. The feedwater flow is regulated by either controlling the pump speed or by using a process control valve. The normal effect of pure water corrosion-erosion (or cavitation) that causes premature seat failure within the valve is amplified because velocities of 10fps + can be reached. The added cost of frequent valve
