Power Boiler Feedwater and Steam - Convergence Training

The water supplied to the boiler, which is converted to steam, is called feedwater. This feedwater system removes any impurities in the condensate, which is steam converted back to water, preheats and pressurizes it then returns it to the power boiler steam drum. The power boiler control system maintains the proper flow of feedwater to the boiler.
