Steam Generation Level Regulation Product Uses …

A deaerator removes excess oxygen from the water before it flows through the high-pressure feedwater heaters and the boiler economizer. From there, water goes into the steam drum where steam is separated and drawn off to the superheater. The remaining water passes through the downcomer and into the bottom of the boiler tubes.
