Boiler Feed Water and Boiler Water - EWT Water Technology

Requirements for the Boiler Feed Water of Steam Boilers: * According to EN 12953-10, an oxygen concentration of < 0.05 mg/L is allowed in the boiler feed water of shell boilers with an operating pressure ≤ 20 bar, thus differing from the above requirements.

4.3 Boiler water should be maintained at pH 11. Generally, the higher the pH (basic), the less soluble some solids are in the water. The lower the pH (acidic), the more soluble these solids are. 4.3.1 Hard scale is most often formed when dissolved solids are deposited directly on a heat transfer surface as water changes to steam.

Characteristics of boiler feedwater - Lenntech

The purity requirements for any feed-water depend on how much feed water is used as well as what the particular boiler design (pressure, heat transfer rate, etc.) can tolerate. Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, …

Boiler Water Conductivity Measurement Fundamentals

TDS = 5,000x0.7μS/cm. TDS = 3,500 ppm. Alternatively, the battery powered, temperature compensated conductivity meter shown next is suitable for use up to a temperature of 45°C. It is necessary to measure the conductivity of the boiler water inside the boiler or in the blowdown line.
