Overview
Boiler water treatment is commonly in industrial boilers and steam raising plants. Ensure that such boiler systems are correctly going on and that they work at optimum efficiency. We must maintain the correct boiler water conditions at all times. It can be accomplished by dosing selected chemicals for boiler water treatment into the feed water. For high-quality steam, boiler water treatment is essential. To regulate steam purity, deposits, and corrosion, it relies on properly controlled water treatment. The Internal Boiler Water Treatment system and external boiler water treatment are two primary boiler feedwater treatment types. The sump in the boiler system is a boiler. Many of the pre-boiler pollutants are eventually received by it. The below three main goals must be fulfilled by the treatment and conditioning of boiler feed water:
- Continual exchange of heat
- Protection from corrosion
- High-quality steam manufacturing
The reduction or elimination of impurities from water outside the boiler is an external treatment. When the level of one or more of the feed water impurities is too high to handle by the boiler system, then we use external treatment. The conditioning of contaminants within the boiler system is an internal treatment. Internal treatment can be used separately or in combination with external treatment.
Different categories of Boiler Chemicals
There are two fundamental classes of boiler chemicals to choose from. One chemical category is for steam boilers, and also the second one is for hot water boilers.
Steam Boiler Chemicals: These comprise Oxygen Scavengers, Amines, Phosphates, Polymers, and Alkalinity builders.
- Oxygen Scavengers: 38 percent, pH < 4, is the most common type. Other solutions are combining with alkalinity contributors and a cobalt catalyst. Usually, these blends are 50 percent dilutions and come in 7 and 10 pH. Using these blends , an alkalinity source, removes.
- Boiler Alkalinity Builders: The most popular boiler alkaline products are Potassium Hydroxide or Sodium Hydroxide.
- Amines: Neutralizing amines are Neutralizing chemicals. Morpholine, Cyclohexylamine, and Diethylaminoethanol. In many dilution ratios, these chemicals can be purchase as a single component or also in a multi-blend.
- Scale Prevention: Phosphate and Polymer Blend.
Hot Water Boilers: A mixture of Sodium Nitrite is the most economical chemical to use.
This is the simplest and most cost-effective way for a boiler system to protect your investment. Besides regular check and ongoing maintenance, we also provide high-quality advanced water treatment chemicals for boilers.
Features of Boiler Chemicals:
- Prepare feedwater before it goes to the boiler.
- Secure and preserve the clean internal boiler surfaces
- Maximize Return Condensate
Some of the most common chemicals that are For boiler water treatment are:
Oxygen scavengers:
These are specifically design to lower the amount of oxygen and oxides dissolved in the water. Oxygen scavengers, such as hydrazine and sodium sulphite, can efficiently eliminate both DO and pure water oxides. You will be able to extract any residual oxygen from the feed water when you add a chemical oxygen scavenger to your boiler water. It protects the boiler from harmful chemical reactions and eliminates corrosion and return lines inside the feed tank. It has been shown that tannin chemicals and sulphite chemicals are potent oxygen scavengers. This oxygen scavenger can work faster if you use sodium sulphite and is especially useful for low-pressure applications. As for tannin, this chemical extracts oxygen from the water while also forming a film resistant to corrosion around the boiler steel.
Alkalinity Builders:
These are explicitly to increase the water’s pH level in which they are present. For steam boilers, pH levels must remain high to avoid corrosion. Moreover, the silica plating in a high-pressure boiler , and maintain the boiler’s proper performance . If your feedwater has a high alkalinity level and water becomes too acidic, then alkalinity builders can be used. To calculate your boiler water’s pH level, all you need to do is measure it with a pH sensor. If the pH levels have fallen too high, alkalinity builders can help you increase the water’s alkalinity. You would be able to protect the feed line and hot well from acid corrosion if you increase your boiler feed water’s alkalinity. The quantity of this chemical you need all depends on how low your feedwater pH level is.
Amines:
Amines are compounds that neutralize and avoid the corroding of the condensate pipe on a boiler. A steam boiler’s condensate water can be extremely corrosive for piping. It will damage your boiler and also force you to fix the problem by making costly repairs. Morpholine, dimethylaminoethanol, and cyclohexylamine are the three forms of neutralizing amines that you can use for boiler water treatment purposes. While these neutralizing amines can be purchased as a single item, most solutions would be blended with all three. They can increase the condensate pH when we add these amines into your boiler water, which significantly reduce corrosion risk. Low pH is to cause high corrosion levels within condensate piping, which can lead to both condensate leaks and steam leaks. You will be providing with better boiler reliability, cleanliness, and safety after adding this chemical to the water in your boiler.
Anti-Scaling Agent:
In order to boost the dispersive properties of any conditioning materials in your boiler water, anti-scaling agents are used. Usually, an anti-scaling agent a mixture of polymers and phosphates. As either natural or synthetic chemicals, these anti-scaling agents are available. To minimize the scale build-up in your boiler, these chemicals serve as softening agents. Scaling can be a big issue for boilers because of how much less effective it makes the boiler to be.
Why is Boiler Water Treatment important?
The treatment of your boiler water is critical as impurities in the water can cause many problems. If you don’t treat the water, it will result in spending a lot of money on machine repairs. Several issues can arise if your boiler water is not treated. Eventually, rising levels of impurities in the water can contribute to scale formation in the boiler. Your boiler will begin to degrade in quality as corrosion sets in, resulting in replacing the boiler sooner than it’s expected. So it’s essential to have a proper boiler water treatment and use appropriate chemicals for its treatment. We at Jateen Trading Co. uses the best practices for the boiler water treatment and high-quality chemicals for their treatment.
