Hot Water Boiler Chemical Guide - ChemWorld
temperature is held above 190° F there is a potential for feed water pump cavitation. – Temperature gauges fail, so holding the tank at 200ºF. – 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

Boiler Water Quality
Boiler Chemicals are used to ensure proper Boiler Water Quality in boilers. The below table is the Total Dissolved Solids or TDS, Alkalinity, and Hardness versus Boiler Pressure. First, knowing the water source is important, whether it is from ponds, rivers, ground wells, or city water. It is essential in determining the type of boiler water treatment chemicals needed.

Well water can have as high as 1,250 ppm of dissolved solids. 1,000,000 pounds of this water will have 1,250 pounds of solids. A 100 hp boiler vaporizing 3,450 pounds of this as make-up water could leave 4.3 pounds of solids behind. 3.5.4 Suspended solids are insoluble …

The consensus is that feedwater oxygen, iron, and copper content should be very low (e.g., less than 7 ppb oxygen, 20 ppb iron, and 15 ppb copper for a 900 psig boiler) and that pH should be maintained between 8.5 and 9.5 for system corrosion protection.

The Importance of Boiler Water and Steam Chemistry
Jan 07, 1983 · The dilution water should be copper-free and contain O-4 ml of HCl/ NOTE 4 -Normally, 2 ml of neocuproine solution is sufficient in a test. However, 4 ml df the reagent is suggested when the sample contains more than 100 (rg of copper or when it is high in heavy metal ions.
