Nov 01 2004 · The permeate concentration is reduced to <15 mg/L of hardness <1 mg/L of silica and ~10 µS of conductivity all well below the designed water quality limits. Using a NF or RO module in this system is a commercially viable option for treatment of boiler feed water at
Apr 18 2014 · This standard applies to steam boilers generating steam at more than 15 psi and hot water boilers generating hot water at temperatures over 250 F or pressures higher than 160 psi. Section IIMaterials: This covers specifications and properties for ferrous and nonferrous materials.
Sep 18 2020 · The water quality standards for the gas-fired boiler: 1) Water oxygen content. Different boilers have certain differences in water quality requirements due to different types and parameters. For example the feeding water oxygen content of 6tph steam boiler should be lower than or equal to 0.05mg/L. Failure to meet this requirement will cause the boiler corrosion and reduce the service life
