concentrations, steam quality can be impaired. In addition, hardness salts can precipitate from the boiler water to form sludge and eventually scale, which deposits on the internal surfaces of the boiler. The result: a serious loss of boiler efficiency, and possibly boiler failure.

IS 10496 (1983): Feed Water, Boiler Water and Condensate

Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high mass to be blown down. Water-tube boilers tend to operate at higher pressures, usually up to 150 bar g. The higher the pressure, the greater the energy contained in the blowdown water.

Water Treatment Requirements for Low and Medium Pressure

Apr 27, 2015 · For the purposes of this discussion, low pressure shall apply to boilers up to 150 psig. These boilers are typically used in space heating applications where the percentage of return condensate is high. Medium pressure boilers fall in the range of 150 to 650 psig. These are typically power generating plants where process steam is required.

Water treatment and maintenance for your low-pressure boiler Introduction Every year, HSB investigates numerous boiler failures. The primary reasons for these failures are poor or non-existent water treatment and little or no preventive maintenance. Monitoring the boiler at start-up, ensuring good water quality, checking for leaks, and

Boiler Water Quality

Always use a softener to ensure good Boiler Water Quality. Chemicals are designed to polish away small amounts of hardness that by-passes the softener. Silica in boiler feedwater can be a problem in larger steam boiler systems. You must maintain a Total OH alkalinity ratio of 3:1 in high pressure boilers to prevent plating of silica. Alkalinity is a measure of the capacity of water to neutralize strong acids.
