Water for the Boiler | Spirax Sarco

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.

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.
