Boiler water

Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam.The term may also be applied to raw water intended for use in boilers, treated boiler feedwater, steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.

Proper Boiler Feed Water Temperature Management

Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.

The Effects of Carryover in Steam Boiler Systems

8/14/2018 · The alkalinity in boiler water can react with these contaminants to produce a crude soap that causes foaming and carryover. Selective vaporous carryover occurs due to the solvent properties of steam. At high pressures, steam actually dissolves a portion of the mineral salts in boiler water.

Is My Boiler Pressure Too High?

A boiler moderates your central heating and your water, though it is important to remember that boiler pressure and water pressure are two separate things. Boiler pressure refers to the pressure of hot water running in your sealed central heating system, while water pressure is the pressure of the water coming through your taps.

Oxygen Control For High- and Low-Pressure Boiler Water Systems

300 PSI), whereas Industrial applications tend to have high-pressure systems (over 600 PSI). System pressure determines which water treatment chemicals are appropriate for oxygen scavenging. For example, in a high-pressure system, the feedwater quality needs to be very pure and free of dissolved solids to avoid causing scale.
