The high-pressure feed heater is a heat exchanger of the shell and tube type which further heats the feedwater before entry to the boiler. Further heat may be added to the feedwater without its becoming steam since its pressure has now been raised by the feed pump.

17/5/2016 · Feedwater Heaters: Not to Be Ignored. Victor Rodgers | May 17, 2016. Power plant feedwater heaters (FWHs) make the most of the heat from condensation to preheat water destined for the boiler. In doing so, they reduce the amount of fuel required to bring the water up to temperature. Unlike their haughty turbine or boiler counterparts, however

Most high-pressure industrial boilers with high purity feedwater use a phosphate-based chemical treatment program for corrosion control. The evolution ofphosphate-based boiler chemistriesfollowed improvements in feedwater quality. Prior to the advent of demineralizers, sodium phosphates were used to precipitate calcium to a calcium hydroxyapatite that was a fluid sludge removable by lower drum blowdown. When demineralized water systems came about, the need for hardness precipitation was replaced by a need for phosphate buffering. The buffering action of the phosphate treatment will minimize the potential for acid and caustic based corrosion. Keeping a clean heat transfer surface is key to minimizing under-deposit corrosion cells. Deposit minimization relies on both the feedwater treatment and polymeric dispersants. Besides causing boiler tube overheat failures, deposits play a role in corrosion. Formation of concentration cells under and within deposits can lead to corrosive conditions at the tube metal surface. As such, the maintenance of clean boiler …
