Dec 09, 2019 · Boiler Water Chloride Test Kits Boiler Chloride Test Kits comes in 1 drop = 2, 5, and 10 ppm. Directions: Fill the vial with 25 ml of boiler water. Add 6 drops of Phenolphthalein Indicator. If the water turns red or pink, add Sulfuric Acid Neutralizing Solution, drop by drop, until it clears.View More
A steam boiler plant must operate safely, with maximum combustion and heat of brine (sodium chloride or common salt) through it, which leaves the resin rich in Water-tube boiler plant is much less tolerant of high TDS levels, and even Ask Price View More Chloride limits in boiler waterView More
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubesView More
Because chlorides do not precipitate in the boiler water, the relative chloride concentrations in feedwater and boiler water provide an accurate basis for calculating the rate of blowdown. The chloride test is unsuitable for this calculation when the feedwater chloride is too low for accurate determination.View More

Formation of chloride ions can be done by controlling the amount and time of boiler blow down. Standard value of chloride ion is less than 300 mg Cl/l. 7. Phosphates. Proper check on phosphates reserve of boiler water should be kept because it reacts with calcium and forms calcium phosphates, which is a major scale forming componentView More
pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.View More
The amount of chloride in the boiler water is a function of the type of boiler and the boiler pressure. High pressure utility boilers have essentially zero chlorides. For low pressure industrial boilers say 150 psi units, boiler water chlorides limits are set on the ideas that:View More
boiler water chloride level should be monitored to ensure the blow down rate is correct. If the chloride level is higher than the recommended maximum, more blow down is needed. If it is low, excess blow down is occurring, resulting in wasted chemicals, water, and heat energy. In some cases the chloride level never approaches the recommendedView More

Corrosion is a relevant problem caused by water in boilers. Corrosion can be of widely varying origin and nature due to the action of dissolved oxygen, to corrosion currents set up as a result of heterogeneities on metal surfaces, or to the iron being directly attacked by the water.View More
Jun 14, 2019 · EPRI does have recommendations on chlorides for power boilers such as for boilers operating under all volatile treatment EPRI recommends <0.22 ppm for 1500 psi boilers and <0.05 ppm for 2500 psi boilers. As an expert in water treatment of industrial boilers, I can say that we barely pay attention to anions at all for most boilers.View More
The mechanism of corrosion of waterwall and superheater tubes by chloride or sulfate deposits is also discussed in detail. In general, corrosion by chloride or sulfates salts occurs at much lower temperatures and is mostly experienced at the waterwall tubes.View More
The resulting protective metal oxide acts as a barrier against further corrosion, which passivates the metal and inhibits further oxidation. Corrosion in the boiler is prevented by maintaining a boiler water condition in such a way that the magnetite layer is retained.View More
CAUSTIC EMBRITTLEMENT Over time, the concentration of sodium carbonate in the boiler increases. Combined with water evaporation, the sodium carbonate forms sodium hydroxide. This makes the water alkaline and results in caustic embrittlement particularly in bends and joints.View More
