Boiler Water Treatment - Why is It Important

Boiler water quality is of prime concern to all boiler operators. The process of water treatment in boilers is not limited to producing high quality DM water. The stringent water chemistry requirements of Supercritical power plants makes water treatment in boilers a very critical aspect of power plant operation. This necessitates the use of a high quality water treatment system.

Boiler feedwater - Wikipedia

2019-10-31 · Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it

Effect of chloride and sulfate ions on crevice corrosion

Crevice corrosion behavior between homogeneous and dissimilar materials of 13Cr and 3.5NiCrMoV steels was investigated in simulated boiler waters containing chloride ions (Cl ) and sulfate ions (SO 4 2), using open circuit potential (OCP) measurements in addition to morphology analysis.Pitting occurred inside the crevice not only on 13Cr steel but also on 3.5NiCrMoV steel in the test
