1. What Are The Causes of Boiler Leakage?

Boiler leakage or boiler water leakage is a complex problem and there may be a number of reasons behind it. By serving large and small boiler application companies, EPCB Boiler has summarized the following detailed analysis of the causes of boiler leakage. We hope it will be helpful to you:

1.1 Water quality Issues

When the water quality used by the steam boiler is poor, impurities and minerals in the water will form scale and attachments inside the boiler. These sediments will adhere to the inner walls of the pipes and industrial boiler walls, affecting the heat transfer efficiency. At the same time, they may cause corrosion and blockage of the pipes, and eventually cause water leakage. EPCB Boiler engineers will recommend the best water treatment equipment based on the customer’s local water quality. to address water quality issues.

1.2 Boiler aging

Material fatigue: After a boiler operates for a long time, its materials will be affected by thermal stress and mechanical stress, gradually causing fatigue. This kind of fatigue may cause cracks or deformation of pipes and connections, which may lead to water leakage. The EPCB Boiler after-sales service team will solve this problem in a timely manner.

Ageing of seals: Seals in boilers, such as valves, flanges, etc., may age, become hard or brittle after long-term use. These aging seals cannot effectively seal and may cause water leakage.

1.3 Improper installation and maintenance

Installation errors: When installing the boiler, if the pipe connections are not tight, the seals are not installed in place or the installation position is incorrect, etc., it may cause water leakage.

Improper maintenance: Regular maintenance and upkeep of the boiler is key to ensuring its normal operation. Improper maintenance, such as failure to clean scale in time, replace damaged parts, etc., may cause the boiler to leak.

1.4 Improper operation

Overload operation: When the boiler is overloaded, its internal pressure will increase, which may cause pipes and connections to bear excessive pressure and rupture.

Frequent starts and stops: Frequent starts and stops of the steam boiler will generate strong thermal and mechanical stress inside the boiler, accelerate material fatigue and aging, thereby increasing the risk of water leakage.

Misoperation: If the operator misoperates or is negligent when operating the boiler, such as improperly adjusting the water level, opening the wrong valve, etc., it may cause water leakage.

1.5 External factors

Natural environment: Extreme weather conditions, such as severe cold, scorching heat, etc., may cause boiler pipes and connections to be damaged due to temperature changes, thereby causing water leakage.

External impact: When the industrial boiler is impacted or squeezed by external objects, its pipes and connections may be damaged, causing water leakage.

In order to prevent and solve boiler water leakage problems, the above factors need to be considered comprehensively. EPCB boiler manufacturers recommend taking corresponding preventive measures and solutions. This includes strengthening water quality management, regular maintenance and upkeep, standardizing operating operations, and strengthening safety supervision. At the same time, for water leakage problems that have occurred, it is necessary to find the cause in time and take effective repair measures to ensure the safe and stable operation of the boiler.


2. What Are The Measures To Prevent Boiler Leakage ?

Boiler Water Leakage Detection

2.1 Strengthen water quality management

2.1.1 Monitor water source quality:

Regularly check the water quality of the boiler inlet water to ensure that the water quality meets the standards. For water sources with poor water quality, appropriate purification measures need to be taken, such as filtration, softening, etc.

2.1.2 Regular blowdown and cleaning:

Blow down the boiler regularly to remove impurities and sediments in the water and prevent the formation of scale and attachments. At the same time, clean the boiler regularly to remove scale and attachments on the inner walls of the pipes and boiler walls.
