### Boiler Water Treatment - Home - Association of Water

– When the feed water pump comes on, the boiling point of water is reduced – Deareators use head pressure (1 psi for every 2.3 feet of height above the pump), where a feed water tank is barely 3 feet above the feed water pumps. – Watch the temperature closely to prevent pump loss due to cavitation.

### Calculating Boiler Chemical Requirements – Water

The feed water supplied to the boiler is equal to the sum of the steam leaving the boiler and the blowdown discharged from the boiler. The feed water rate can be estimated using the following equation: Feed Water Rate (gal/day) = Steam Generation Rate (gal/day) ÷ [1 – (1 ÷ Cycles of Concentration)]

### Blowdown in Boiler | Boiler Blowdown Calculation Formula

Blowdown in Boiler Definition. Blowdown in Boiler, Usually, water which is fed to the boiler contains high Total Dissolved Solids (TDS) content as well as other dissolved and undissolved solids in it. On heating water or converting water to steam, these dissolved solids do not evaporate and gets separated from water or steam and settled at the bottom of the shell.
