What is boiler water treatment?

What is boiler water treatment?

Why boiler water treatment is required? Its purpose is to properly react with feed water hardness, condition sludge, scavenge oxygen and prevent boiler water foaming.
The water treatment facilities purify and deaerate make-up water or feed water.

What is boiler water and how is it treated? Boiler water treatment is a type of industrial water treatment focused on the removal or chemical modification of substances potentially damaging to the boiler. Varying types of treatment are used at different locations to avoid scale, corrosion, or foaming.

Do boilers need water treatment? Why is Boiler Water Treatment Required

What is boiler water treatment? – Related Questions

What is boiler water treatment chemicals?

A complete water treatment programme for a steam boiler will usually include a chemical oxygen scavenger, alkalinity builder and polymer sludge conditioner and, depending on the application, may also incorporate a phosphate treatment and a condensate line treatment.

What are the 2 types of boiler feed water treatment?

The treatment of boiler water can be put into two parts.
These are internal treatment and external treatment.
(Sendelbach, p.
131) The internal treatment is for boiler feed water and external treatment is for make-up feed water and the condensate part of the system.

What is the pH value of boiler water?

Boiler water should be maintained at pH 11. Generally, the higher the pH (basic), the less soluble some solids are in the water. The lower the pH (acidic), the more soluble these solids are.

Can you drink boiler water?

Hot water systems like tanks and boilers contain metallic parts that corrode as time goes by, contaminating the water. Hot water also dissolves contaminants in pipes faster than cold water. And no, boiling the water does not make those contaminants (like lead) go away.

What is TDS in boiler water?

When a boiler generates steam impurities in the feed water will concentrate in the boiler water.
The concentration of impurities is often termed TDS – Total Dissolved Solids (ppm) and can be measured using a conductivity or density method.

What type of water goes in a boiler?

The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water).
The make-up water is usually natural water either in its raw state, or treated by some process before use.

What temperature is boiler feed water?

To avoid the “Improperly Heated Feed Water” condition described above, the boiler feedwater should be heated to at least 180 °F when using a feedwater tank and 227 °F when using a deaerator.

What is hardness in boiler water?

Hardness. The hardness of water is caused by calcium and magnesium ions which will vary greatly throughout the country depending on the source of the water. In boilers the hardness of the water can cause the formation of scale and sludge or mud. The hardness must be removed in the makeup water to the return system.

Why is the pH in my boiler water high?

When the boiler water pH drops below about 8.
5, a corrosion called acid attack can occur.
Contamination can also occur from process leaks of acid or acid-forming materials into the return condensate system.
Caustic Attack.
Caustic attack on boilers is a localized attack due to extremely high pH (12.
9 +).

What is phosphate used for in boiler water?

Phosphate compounds are common additives for boiler water treatment. Phosphate compounds react with any remaining hard water compounds to create a soft sludge that is eliminated through blowdown. Phosphates also scavenge (or remove) any remaining oxygen and create a pH buffer to minimize corrosion potential.

What is P alkalinity in boiler water?

P-ALKALINITY:- THIS TEST IS CARRIED TO FIND OUT THE PRESENCE OF ALKALINE IN BOILER WATER.
BOILER WATER SHOULD BE ALKALINE TO SAVE IT FROM CORROSION.
ALKALINITY IS DUE TO HYDROXIDE AND CARBONATES AND HYDROXIDE.
P ALKALINITY IS USED TO FIND OUT ALKALINITY DUE TO CARBONATES.
“P” STANDS FOR PHENOLPHTHALEIN ALKALINITY.

Where is boiler feed water?

Feedwater is water that undergoes purification or preheating and is then supplied to boilers for hot water and steam production, or it can remain still. It is typically found in thermal power plants where it is stored and conditioned in tanks, known as boiler feedwater.

Why ammonia is dosed in boiler?

Ammonia is added to the steam drum, or to the deaerator storage tank, either as ammonia or as amine. It is used to control the pH of the condensate returned to the system from the process. It can do this because it evaporates and is carried out of the boiler with the steam.

What is Boiler Conductivity?

A common problem that’s found in boiler water is the presence of high conductivity, which refers to the ability of the water to conduct an electrical current. Controlling the conductivity of water is an essential component of making sure that a boiler functions properly.

What is pH full form?

In chemistry, pH (/piːˈeɪtʃ/, denoting ‘potential of hydrogen’ or ‘power of hydrogen’) is a scale used to specify the acidity or basicity of an aqueous solution.

What are the main parts of a boiler?

What are the Main Components of a Commercial Boiler
Burner. The burner is the part of the boiler where air mixes with the fuel source and combusts.
Combustion Chamber.
Heat Exchanger.
Controls.
Supply Lines and Return Lines.
Circulator Pump.
Exhaust Stack.
Conclusion.

What is the pH of steam?

The safe pH range for steam boilers is between 8.5pH & 12.7pH, whilst the recommended level is between 10.5pH & 12.0pH. Boiler water with a pH of 10.5 contributes 12.6mg/l towards the boiler TDS, whilst at a pH of 12.0 it increases to 400mg/l and at 12.5pH the value is 1264.9 mg/l a 100 fold increase.
