What are the Reasons for leakage in boiler tubes?

1. Tube Corrosion

The most common causes of boiler leaks are corrosion and system component failure. While this may theoretically happen anywhere in the boiler, the most common cause of leaks is corrosion in the tubes themselves.

Oxygen pitting can cause tubes to deteriorate over time. This occurs when the boiler water contains too much oxygen, causing corrosion when iron or other elements react with the oxygen molecules. The lower the boiler feedwater temperature, the more oxygen is injected into the boiler, increasing the danger of oxygen pitting within the tubes. You can limit the risk of oxygen pitting by keeping the feedwater at a higher temperature.

It's ideal to employ what's known as an oxygen scavenger to assist avoid tube corrosion and oxygen pitting. Sulphite or bisulphite ions, for example, react with dissolved oxygen to generate sulphate, effectively eliminating excess oxygen from your system.

2. Corrosion of Unified Units

Units can have uniform corrosion throughout the entire system, in addition to corrosion in isolated areas of the boiler. Low pH levels in the boiler are usually the cause of this.

Because of the higher levels of acidity in the water, when pH levels are below 8, your system is more prone to corrosion. Even though a pH of 7 is theoretically neutral, you risk slipping into acidic territory if something goes wrong even slightly.

At Netsol, we prefer boiler systems with pH levels of 10 or above to guarantee that corrosion is maintained to a minimum throughout the unit. It's recommended to use a pH or alkalinity adjuster.

3. Scale of a Boiler

Another problem that can occur in boilers is scale, which can lead to tube leaks. Scale build-up in a boiler can reduce heat transfer, which can lead to tube leaks as pressure rises. Blowdown and pressure release valves may become clogged as a result of this.

Water softeners and scale inhibitors can be used to reduce scale in a boiler.

BOILER DESCALE solutions are designed specifically for boiler systems, with the ability to solubilize pollutants usually present in boiler feedwater for the best chance of keeping boiler heat transfer surfaces clean.

4. Thermodynamic shock

Anyone who has ever tried to wash a hot dish in cold water has experienced thermal shock's fast and potentially fatal effects. When a boiler is filled with cold water, this can happen. The subsequent temperature shock can cause the tubes in a boiler to break or leak, as well as most of its other components. Make sure your boiler feedwater is at the right temperature before adding it to the boiler.

5. Improper Water Treatment in Boilers (Post Installation)

Consider the following scenario: a corporation has recently spent thousands of dollars installing a brand-new boiler and is ready to turn it on. At this important juncture, they must develop a proper water purification scheme to help protect their investment.

Running the boiler with untreated water will result in early tube corrosion and system scaling, potentially causing the boiler to fail well before its specified life cycle. Boiler water treatment is critical to keeping the boiler in good working order and lowering maintenance costs. By ignoring this critical preventive maintenance task, you'll drastically increase downtime and the system's overall cost.
