Boiler Chemicals - Oxygen, Scale, and pH Adjustments

Types of Boiler Chemicals for Hot Water Boilers By far the most popular hot water boiler chemical is a sodium nitrite blend. This chemical blend often contains a low percentage of borate, silicate, tolytriazole, and sodium hydroxide. Nitrite is the ideal chemical for a hot water boiler since it creates superior passivation that protects your

If makeup is demineralized water at 4.14 MPa (600 psig) to 6.89 MPa (1000 psig), boiler water alkalinity should be that in table for 6.90-10.34 MPa (1001-1500 psig) range. e Refers to free sodium or potassium hydroxide alkalinity.

Jun 12, 2017 · Many industrial boilers operate in the range of 601 to 900 psig or higher, but as working pressure increases, feedwater quality requirements become progressively more stringent, and the nature of the water treatment program must also vary. Certain industrial boilers are designed to operate in the high pressure range of 1000 to 2000 psig.

Boiler Chemical Cleaning: Doing It Correctly

Industrial Boiler An important consideration regarding the use of chemi- cals in a boiler is its decomposition products. Sulfite, for example, is not recommended for use in boilers operating above 900 psig because corrosive hydrogen sulfide and sulfur dioxide are formed upon decomposition. On the other hand, HEDP and PBTC breakdown into ortho-

May 04, 2016 · For boilers operating up to 300 psig, the accepted alkalinity range is 200 ppm to 700 ppm, with P being 60% to 80% of Total Alkalinity. Balances alkalinities are no guarantee of clean, trouble-free boilers. However, this is one of the important factors, together with others, that must be properly controlled if the boiler is to be kept clean.
