5/10/2017 · Continue turning on and off the boiler to maintain the temperature in the range of 100-130F. Check pH every 15 minutes; (should be 1 or 2). If higher, add Scalzo to depress the pH back to 1-2 pH. Continue step 5 until pH remains at 1 or 2 for 120 minutes or more, depending on scale build-up. The system is then as clean as will be with the

EC: Lesson 11. Scale and sludge formation in boilers

11.2 PREVENTION OF SLUDGE FORMATION : (1) By using well softened water, (2) By frequently 'blow-down operation', i.e., drawing off a portion of the concentrated water. Scales are hard deposits, which stick very firmly to the inner surfaces of the boiler. Scales are difficult to remove, even with the help of hammer and chisel.

12/5/2011 · In a boiler, two types of corrosion are prevalent: 1.) Oxygen pitting corrosion, seen on the tubes and in the preboiler section. 2.) Low pH corrosion, seen in the condensate return system. Corrosion of either type can lead to failure of critical parts of the boiler system, deposition of corrosion products in critical heat exchange areas, and

Boiler Scale Inhibitors | ChemTreat, Inc.

Boiler scale is a deposit that forms directly on heat transfer surfaces when constituent solubility limits are exceeded and the resulting compounds precipitate onto the tube surfaces. Such deposits may contain calcium, magnesium, phosphate, iron, and silica. When calcium precipitates in the form of calcium carbonate, it forms a tenacious boiler
